February Blooms in my Georgia Garden: Hellebores

Since Georgia has many days of nice warm weather in Winter, I'm adding as many winter blooming plants as I can find to our garden. Hellebores are evergreen perennial plants that bloom after Christmas in a rainbow of colors in shades of magenta, rose, mauve, and cream. Some blooms are even speckled. 

Often called Lenten Rose or Christmas Rose, Hellebores aren’t really roses at all, but are in the buttercup family. Hellebore is a very low-maintenance plant that thrives in dry shade—that’s right, dry shade! 

When not blooming, Hellebores have interesting, shiny, dark green foliage with leaves often serrated or even palmate.

It is a long-lived perennial offering years of beauty in the shade garden.

Hardy in USDA Zones 4-8, hellebores require no special care. 

They spread with time, self-sowing to form clumps up to 2 feet across in just a few years. Amend the soil well with organic matter when planting, and you’ll be rewarded with many years of beauty. 

Hellebores are a great substitute for Hosta, but are even better. Hellebores are evergreen and deer proof - the deer will not eat them! 


No matter what you decide to plant in your garden, get out there and enjoy it. And remember to thank God for the rain we’ve received!

October Blooms in my Georgia Garden: Mistflower

I love Eupatorium coelestinum for its showy bloom clusters in early fall. This plant is usually referred to by one of its common names which include Hardy or Perennial Ageratum and Mistflower. 

Eupatorium is a deciduous perennial native American plant in the same family as Joe Pye Weed. The bright periwinkle blue blooms of Eupatorium coelestinum attract a lot of attention in September and October, when most flowers have stopped blooming. Mistflower contrasts nicely with fall-blooming asters and the common fall mums.

The plentiful 4-inch flower clusters atop tall stems resemble the shorter annual ageratum, but Hardy Ageratum comes back bigger and better every single year.

With large clumps of bright blooms visible from a distance, Mistflower is a good candidate for a roadside garden.

Hardy Perennial Ageratum prefers full sun, fertile soil, and regular water, but this hardy variety can tolerate periods of drought. Like other varieties of Eupatorium, this one can grow in wet soil too.  We have a patch behind the greenhouse that has taken over a shady spot where the sprinkler keeps the soil evenly moist to wet.

This very showy and assertive perennial will reach heights of up to 4 feet tall, but it can be kept mowed to only a few inches. Just to give you a hint of its vigor, Mistflower is in the mint family.

This is a perennial plant that looks best in naturalistic informal gardens. It grows very well in my shade garden, where its blooms seem electrified in September.

Perennial Ageratum emerges late in spring, so be careful not to uproot it when doing your spring weeding. 


Cut back once or twice in summer to promote bushiness and more blooms, and to keep it from coming into full bloom too early.  I always want mine to wait and bloom in October.

September Blooms in my Georgia Garden: Jerusalem Artichoke

The tallest perennial in our garden is the Jerusalem Artichoke. Helianthus tuberosus is a perennial sunflower native to the Eastern United States. This is a great plant for the Fall garden at the back of the border.

Also known as Sunchokes, the Jerusalem Artichoke is a perennial plant that grows from a tuber. The tuber is edible and can be used like a water chestnut in salads or stirfry.

The flower is a lovely sunflower type bloom. The golden yellow blooms attract all kinds of pollinators. The blooms are fragrant and smell like chocolate!

Our patch of Sunchokes is over 10 feet tall this year, thanks to all the rain we received early in the Summer.

Native Americans ate the tubers and traded them to other tribes. Once European settlers moved in an found out about this native tuber that could be used like a root vegetable, they began shipping the tubers back home to Europe. The tubers were truly appreciated by the French who like adding it to soups.

Contrary to what you might think, Jerusalem Artichokes have nothing to do with Jerusalem and they are not artichokes. The tubers might taste something like an artichoke. These tubers became so popular in the early 1600's that they were cultivated as a crop and shipped to other areas. They have sense naturalized and it is now impossible to know the original native range. They can be found growing from Canada and the state of Maine, as far West as North Dakota and Texas and down South into Flo
rida.

If you'd like to have a patch of Sunchokes, keep in mind that they multiply more than rabbits! Each little piece of tuber will make another plant. So once you have Sunchokes, you'll always have them. This is truly a perennial you can plant and forget.

Jerusalem Artichoke tubers are best dug in Fall or Winter, depending on your climate. Clean dry tubers will keep in the refrigerator for up to 2 months. They are good eaten raw in salads or sliced into stirfries or steamed and eaten like a potato. Sunchokes are a nutritious tuber high in protein and iron and surprisingly low in starch. Unfortunately, the tubers cause severe flatulence in some people, so you might not want to eat them before going out.

And of course, leave it to the Germans to figure out a way to make a liquor out of Jerusalem Artichokes! In Germany, the tubers are made into a type of Brandy and other types of alcoholic beverages.

Due to its wide growing range, Jerusalem Artichokes can obviously be grown all over the United States. Plant them in full sun in soil well amended with compost. Once the plants emerge, mulch them well to retain moisture and keep down weeds. Water well during periods of drought to encourage larger tubers for eating.

June Blooms in my Georgia Garden: Hibiscus moscheutos

Annabelle Hydrangea isn't the only Southern native shrub with voluptuous blooms. Just take a look at this native Hibiscus! Hibiscus moscheutos displays blooms up to 12 inches across. The blooms on her remind me of the huge dresses worn by Southern Belles on the movie Gone with the Wind.

Hibiscus moscheutos Lord Baltimore

Also known as Swamp Mallow, Dinner Plate Hibiscus (Due to the huge diameter of the flower), and Rose Mallow, Hibiscus moscheutos is native to marshes in the Southeastern United States. 



Many new varieties of this hibiscus have been developed, resulting in a wide range of bloom colors and interesting foliage.

The huge blooms up to 12 inches across begin opening in late June or early July in our Georgia garden and keep coming until cool weather arrives in the Fall. Although each bloom lasts just one day, a large plant can sport several blooms at one time. Flowers come in many different shades of pink, red, or white. They might be a solid color or have a red eye or some type of variegation in the bloom.

Like Hibiscus coccineus, this plant will grow very fast if it is happy in the spot where it grows. Give it plenty of room, because by mid-summer, it can be 5 feet tall and just as wide. Rose Mallow, like other perennial hibiscus, will die to the ground in Winter and regrow from the base in late Spring.

This fabulous Hibiscus is as easy to grow as Hibiscus coccineus, as long as you have a spot in full sun and can reach it with a hose.  In my garden, this hibiscus has proved to be quite drought tolerant, as long as I give it a drink of water when I notice the leaves drooping from thirst.

Hibiscus moscheutos has a larger hardiness range than coccineus, so it can be grown in gardens further north. According to the USDA Hardiness Zone Map, Hibiscus moscheutos can be grown in zones 5-10.

Groundcovers: An Important Part of a Southern Garden

I love groundcovers. There’s just something about them that makes me want to have every one I see. 

Groundcovers can be an important addition to our Southern gardens. They act as a living mulch, helping to conserve moisture around trees and shrubs.  

Many groundcovers are evergreen, so they add beauty to the garden in every season. There are groundcovers that bloom, and even groundcovers that make berries! 

Groundcovers can be found that thrive in sun, shade, and even the most difficult dry shade. 

Whether your taste for plants leans toward the exotic, like Hellebores and Rohdea, or if you prefer native plants, such as native ferns, consider adding them beneath the shrubs in your garden. 

There are many native groundcovers that are evergreen, and some even produce berries, like Mitchella (Partridgeberry). Groundcovers like creeping phlox can help control erosion. 

Ajuga Bronze Beauty
Good groundcovers for sun include the sedums, ice plant, and rudbeckia (Black eyed Susan.)  Certain rose varieties also make excellent groundcovers. 

Ajuga is a great groundcover for crowding out weeds in shade or partial shade. It is not invasive.

English Ivy Overtakes the Garden
Beware of groundcovers that can take over the garden, seeming to eat other plants alive, crowding out everything else. Instead of invasive English Ivy or the popular Japanese pachysandra, try our native pachysandra, Allegheny Spurge. Or if it’s a vine you’re after, plant Crossvine, Carolina Jasmine, or Red Trumpet Honeysuckle—all native vines that will not overtake your garden.  

Texas Star Swamp Mallow: Native Hibiscus

Hibiscus coccineus, Texas Star, Swamp Mallow
Shady Gardens Nursery
One of the showiest summer bloomers in our garden this time of year is the Texas Star Hibiscus. A native plant of the Southeastern United States, Hibiscus coccineus is also known as Swamp Hibiscus, probably due to its love for moist soil.


Hibiscus coccineus is very easy to grow. It grows well near a pond or stream, and really enjoys a soggy spot. We have no pond, stream, or soggy spot in our garden--our Hibiscus is located in ordinary garden soil (that means dry hard clay in Georgia language). Admittedly, I do water it on occasion, but it grows bushier each year--we've had it several years now.


You can grow Hibiscus coccineus if you live anywhere in the south and as far north as USDA Zone 6!



Even before blooms begin in summer, Texas Star is a spectacular presence in the garden. Palmate leaves resemble Japanese Maple foliage and even have a reddish tinge.

Blooms are showy red star-shaped flowers appearing throughout summer and into Fall. The flowers can be up to 6 inches across!

Hibiscus coccineus dies down to the ground in winter but re-emerges in spring. By mid-summer this hibiscus will be 6-8 feet tall and look more like a shrub than an herbaceous perennial.

Texas Star Hibiscus does need full sun to bloom well, and you'll need to water it weekly when rainfall is absent. Also a regular application of compost or composted manure will keep it growing well for you.

Perennial Plant of the Year: Amsonia Hubrichtii, Blue Star

The Perennial Plant Association has already chosen the 2010 Perennial Plant of the year. Amsonia hubrichtii, often known as Blue Star, is native to the state of Arkansas, but grows well in most parts of the country.

Amsonia Hubrictii is at its best in Fall
Amsonia hubrichtii has very fine-textured foliage which makes it ideal for pairing with ornamental grasses.  

Clusters of blue flowers in May are lovely, but to me this plant comes alive in fall. I'm crazy about the bright golden color that develops with the onset of cooler weather. 

The fact that this plant grows well in both full sun or part shade makes it an easy choice for just about every garden. Like most native plants, Amsonia is drought tolerant once established. 

Probably another reason this perennial is so favored is its lack of problems with insects or disease. I have not noticed the deer munching on it either.

As you can see in the above photo, when massed in groups of 5 or more, Amsonia hubrichtii makes quite a show.

Hibiscus: Choose Native for an Easy, Beautiful, Low Maintenance Garden

Every summer many, many people purchase the Tropical Hibiscus to place on their patio, porch, or around their pool. While it is true that the Tropical Hibiscus is beautiful and really does lend a tropical look to the garden, it will die to the ground with the first frost unless you live in the sub-tropical states. And if you've ever tried overwintering one indoors, you know how difficult that can be!

Instead, consider our American Native Hibiscus varieties. There are several, and in my opinion they are much more beautiful than the Tropical Hibiscus. Our native hibiscus is an herbaceous perennial plant that grows to shrub size each summer.

Hibiscus coccineus has bright red star-shaped blooms all summer on tall stems. This native hibiscus is known by many common names, among which are Texas Star Hibiscus, Swamp Hibiscus, and Swamp Mallow. The Swamp Hibiscus loves consistently moist soil but grows well in my garden with only a weekly watering. Hibiscus coccineus is beautiful even when not in bloom, having reddish-tinged green leaves shaped like maple leaves. Some visitors have claimed it looks like marijuana, but I can't say for sure, since I've never seen a marijuana plant. Perhaps they're telling on themselves! What do you think?

'Very spectacular' is the best description for Hibiscus moscheutos or Swamp Mallow. Blooms are the size of a dinnerplate! See for yourself:
Hibiscus moscheutos growing alongside Rudbeckia Goldsturm

Hybridizers have developed many types and colors, but all are beautiful and any one would be a show piece in your garden.

The native hibiscus is so easy to grow that it would be a shame not to have one in your garden. Hibiscus coccineus is hardy as cold as USDA Zone 6 and Hibiscus moscheutos is happy in even colder temperatures found in USDA Zone 4! Wow! They are deciduous plants but will return in May each year with no special care.

Baptisia Australis False Blue Indigo: 2010 Perennial Plant of the Year

Baptisia Australis, otherwise known as False Blue Indigo, has been named Perennial Plant of the Year for 2010. This award is much deserved. Baptisia is one of the easiest plants of all to grow, and it's a native!

The blue-gray foliage of Baptisia Australis is lovely all season, but this plant has many wonderful features. Leaves are trifoliate, reminding me of clover. The plant is upright, for the most part, and doesn't require staking unless it's getting too much shade. Since Baptisia australis grows up to four feet tall, plant it behind shorter perennials.

Blue violet pea-like blooms stand well above the foliage, providing a tall backdrop for lower growing plants. The bloom stems can be up to 12 inches tall, so Baptisia is an excellent cut flower. Blooms last up to a month on the plant, but are also long-lasting in a vase where they can be enjoyed up close. 

Once blooms are spent, do not deadhead this plant or you'll miss the next show. By late summer, blooms have given way to showy black pods resembling peas. The black pods hanging on strong stems are lovely and make attractive additions to floral arrangements and wreaths for late summer. In addition, these pods are full of viable seeds which you can use to make more of these lovely plants for your garden and for your friends.

This plant grows best with full sun and well-drained soil. Once established, Baptisia is very drought tolerant.

This Perennial Plant of the Year can be grown just about anywhere with its broad range of growing zones, since it's hardy anywhere in USDA Zones 3-9.

Four Oclock: Fragrant Blooms for the Evening Garden


If you like fragrant plants, the old-fashioned Four Oclock will be one of your favorites. Small pink blooms scent the garden with their sweet perfume every evening during summer. Mirabilis jalapa is a shrub-like multibranched perennial plant that emerges each spring from a large carrot-shaped tuber. The common name Four Oclock comes from its fascinating habit of opening its blooms around 4 oclock in the afternoon. That alone is enough to intrigue me, since I have a natural interest in plants with unusual traits. Although it's called Four Oclock, in our garden Mirabilis actually opens her blooms around 5:30 pm, perfuming the air right about the time it begins to cool off enough to sit in the shade on the patio.
Four Oclock is very easy to grow. Easy to please, four oclock can be grown in sun or shade. Our plants get morning sun and afternoon shade, but four oclock grows equally well in full shade with a reasonable amount of water. She's not a water hog, but good soil with regular water will keep the plant looking healthy and green with plenty of those fragrant blooms. Just so you'll know, plants in our shade garden get very little water, yet still bloom and multiply with profusion. Plants in the sun that receive occasional water perform just about as well as those in dry shade. The few Four Oclocks we have in dry sun are just surviving.
I can't really describe the fragrance--it's just a sweet, pleasant scent that invites me to relax outdoors. You might not notice the scent until your plant gets large with many blooms. And if you're never outdoors in the evening, well...you'll just miss out entirely.
Another important feature of the fragrant Four Oclock is that hummingbirds just adore it! The hot pink blooms are tubular and full of nectar for both butterflies and hummingbirds. You'll further enjoy sitting on the patio observing the tiny creatures flitting about around the plants.
Four Oclock dies to the ground with the onset of winter in colder zones, but re-emerges again in late spring. Hardy in USDA Zones 7-11, mirabilis can be grown anywhere in the southern half of the United States.
I must tell you also that Four Oclock is definitely a reseeder. Toward the end of summer you'll notice small black cannonballs on the plants and the ground beneath. Those are very viable seeds. If you've had no luck growing Four Oclock from seed, that's because these very hard seeds need a cold treatment to break them. It's best to plant them in fall, but most gardeners don't think about it then and seeds often are not available in the big box stores at that time of year. You'll have nearly instant gratification if you go ahead and purchase a tuber instead. Heavy black carrot-shaped tubers will send up a stem very quickly after planting in warm summer soil. Four Oclock tubers are available for summer shipping from Shady Gardens Nursery.

Italian Arum for the Winter Shade Garden


An unusual perennial I enjoy seeing in the winter garden is Italian Arum. Just as the Hostas disappear for the winter, the beautiful deep green leaves of Arum Italicum emerge. The variegated leaves are arrow-shaped and very unusual, sometimes growing quite large—up to 12 inches long on mature plants. Italian Arum is a tuberous perennial, which is probably why it is so hardy and tolerant of the drought so common in Georgia. The leaves are variegated green and white and last until May. Mature plants produce an Arum-type spathe in spring followed by bright red berries that remain on the stalk even after the leaves have disappeared. Italian Arum forms a nice clump of leaves about a foot tall, and is a great companion plant for any perennial that dies down for the winter. It grows well with hosta, ferns, and hellebores. As the hosta leaves emerge, Italian Arum will go to sleep for the summer, storing energy for an even better show the next fall. An added bonus is that deer will not touch Arum Italicum! For information on how to purchase this plant, click here. I hope you’ll enjoy the warm spells we have in between the cold snaps by getting outside, and remember to pray for the regular rain showers to continue!

Rohdea: Beautiful Year Round in Dry Shade!

Rohdea Japonica, also known as Japanese Sacred Lily, is a low-growing evergreen plant that is a great substitute for Hosta. Rohdea actually thrives in dry shade gardens, and is not bothered by deer. A native of the Orient, Rohdea should be more widely planted here. Its low-maintenance and tolerance for poor, dry soil make it an easy plant to grow, even for busy gardeners. The 1 foot long deep green leaves form an upright vase-shaped clump that will cover a 2 foot area in several years. In late fall the insignificant flower stalks will develop into a 6-inch stalk of bright red berries at the base of the plant--just in time for Christmas! The berries are eaten by birds and squirrels which help to disperse the seed for more plants in the garden. Usually difficult to find in the United States, Rohdea is highly prized in Japan, with some fancy-leaved varieties often selling for thousands of dollars. If you can find it, Rohdea is definitely worth planting in the garden. Rohdea Japonica needs shade and will even grow in very deep shade with little water. This drought tolerant plant is perfect for a xeriscape garden in shade. Hardiness: USDA Zones 6-10.

Hellebores: Winter Blooms in Dry Shade Gardens


Since we have many days of nice warm weather here during the winter, I like to find plants that will bloom in winter. Hellebores are evergreen perennial plants that bloom after Christmas in a rainbow of colors in shades of magenta, rose, mauve, and cream. Some blooms are even speckled. Often called Lenten Rose or Christmas Rose, Hellebores aren’t really roses at all, but are in the buttercup family. Hellebore is a very low-maintenance plant that thrives in dry shade—that’s right, dry shade! When not blooming, Hellebores have interesting, shiny, dark green foliage with leaves often serrated or even palmate. It is a long-lived perennial offering years of beauty in the shade garden. Hardy in USDA Zones 4-8, hellebores require no special care. They spread with time, forming clumps up to 2 feet across in just a few years. Amend the soil well with organic matter when planting, and you’ll be rewarded with many years of beauty. Hellebores are a great substitute for Hosta, but are even better. Hellebores are evergreen and the deer will not eat them! No matter what you decide to plant in your garden, get out there and enjoy it. And remember to thank God for the rain we’ve received!

Plants for a Dry Shade Garden: Native and Not!

If you have dry shade in your garden, you know what a challenge it is to find plants that will grow in those conditions. What plants grow well in dry shade? This is a list of some of the plants we’ve found to grow well with little or no supplemental water. As I said, this is just a list, but if you'll check back often, we'll add plant profiles as time permits.

Shrubs:
Strawberry Euonymus
American Beautyberry
Native Azaleas – Alabama and Florida (Piedmont is moderately drought tolerant as well)
*The straight species ones have done much better for us—the named hybrid varieties haven’t survived the drought in our garden
Oakleaf Hydrangea
Red Buckeye
Sweetshrub
PawPaw
Winter Honeysuckle (Lonicera fragrantissima)
Arrowwood Viburnum


Perennials & Groundcovers:
Asters (Shade-loving varieties, like wood aster)
Ageratum (the hardy perennial one)
Columbine (Aquilegia)
Dwarf crested Iris
Hardy Geraniums
Native Wild Ginger
Solomon’s Seal
Pachysandra Procumbens (Allegheny Spurge)
Pussytoes is a very cute little native plant with fuzzy silver leaves like lamb’s ear.
Rudbeckia (Blackeyed Susan) does surprisingly well in dry shade if the shade is not too dense. We have several patches planted in shade, and they seem to bloom just as well as the ones in full sun. They bloom just a little later in the season when in shade, which works out just fine for me.
Purple Coneflower does equally well in shade.


Ferns:
There really are some ferns that grow just fine in dry shade.
My favorite is Christmas Fern, because it’s a native plant, and it looks a lot like the popular hanging basket fern, Boston Fern.
It looks great all summer, in spite of no rain or supplemental water at all. Plus it’s evergreen.
Autumn Fern isn’t native, but it’s my 2nd favorite, because it too is very drought tolerant and evergreen.
Dixie Wood Fern is a very large fern that is moderately drought tolerant, although it prefers moist soil.
Eastern Wood Fern is an evergreen native fern that grows well in dry woods. It might move into 1st place in our garden, if it continues to do well.


Vines:
Carolina Jasmine/Jessamine naturally occurs most often in dry shady woods. We were lucky to have this one already growing in our woods, and it grows well and blooms in spite of no supplemental water.
Red Trumpet Honeysuckle (Lonicera sempervirens) also usually occurs in the woods but blooms better in the sun. It tolerates dry shade very well, but blooms less in the shade.
Virginia Creeper is a deciduous native vine with beautiful red fall color that is often mistaken for poison ivy.
I won’t mention the non-native vines for dry shade, but there are some. Many of the popular ones are quite invasive. If you need more information on these, let me know.


Since native plants are my favorite, I tend to concentrate most on them, but I’d be telling a story if I said we don’t grow anything else. We do try to avoid invasive plants, but many non-natives provide a lot of easy-care beauty in our shade garden. You really can’t beat these for a dry shade garden:
Acuba
Ajuga
Aspidistra (Cast Iron Plant)
Daphne odora
Gardenia (once established)
Hellebores (Lenten Rose)
Holly
Hosta
Mahonia (Leatherleaf)
Pieris
Mondo grass, also a non-native plant, is a great performer.
Pittosporum

Rohdea (Japanese Sacred Lily) – makes a great
substitute for Hosta, since it’s evergreen and deer- resistant.

Pittosporum
Viburnum (there are many types, both native and non-native)
Yew
*In addition to being evergreen and deer-resistant, both the Aspidistra and Rohdea grow well in even very deep shade.

June Blooms in my Georgia Garden: Oakleaf Hydrangea

This time of year our garden is always bursting with blooms, but this year has been a little different. Due to a very mild winter, everythin...
