May Blooms in my Georgia Garden: Mock Orange

Philadelphus coronarius
Sweet Mock Orange or English Dogwood

Blooms are spectacular this year on my Philadelphus coronarius, most often referred to as Sweet Mock Orange or English Dogwood. Our established shrub is completely covered with the fragrant dogwood-like white blooms.

Philadelphus coronarius is a deciduous shrub that grows quickly into a large shrub, so give it plenty of room. 

Because of our very mild winter, Mock Orange bloomed a little earlier than usual this year. Usually blooming in late May, the Mock Orange reached its peak bloom the first week of May here in our Georgia garden.

The white flowers with 4 petals smell like orange blossoms, hence the common name Mock Orange and resemble blooms on the Dogwood Tree. Leaves are tender and dark green. On the Sweet Mock Orange, even the bark is lovely, which is exfoliating and orange-tinged. 

This large growing shrub will eventually be up to 12 feet tall and just as wide with a rounded habit, so it's perfect at the edge of the property. 

Philadelphus coronarius can be grown in full sun to light shade, but ours is in pretty much full shade here in Georgia. It might get a little peak of morning sun, but I don't think so. 

Although rich fertile soil is best, our soil is hard clay, and our large shrub gets no supplemental water. This year we received more than enough rain during the Winter and Spring, which might be why our plant showed out so well this time.

Mock Orange is a popular old-fashioned shrub in the Southeastern states, and although it might look delicate, it can be grown in most of the United States, since it is hardy in USDA Zones 4-7.

If you want a hedge of Mock Orange, for Summer privacy perhaps, space them about 5 feet apart for good screening. The shrubs will quickly grow to fill the space. 

If pruning is needed, do so immediately after blooming by removing old canes at the base and cut back remaining branches to create a rounded shape. If your space allows it, don't prune your Mock Orange at all. 

Late Summer Blooms for the Georgia Garden

By the end of summer, many plants have grown tired of providing blooms for our garden. Sometimes it can be a challenge to find plants that will fill in this difficult time with flowers. A diligent gardener can find quite a few plants that bloom in late summer. 

You’re probably familiar with Black-eyed Susan and Butterfly Bushes, providing the garden with blossoms this time of year no matter how hot it gets, attracting butterflies by the hundreds. You’ve seen Japanese Honeysuckle on the side of the road, or perhaps you’re even plagued with its invasive qualities in your own garden. 

But have you seen our native Red Trumpet Honeysuckle? Lonicera sempervirens is a non-invasive evergreen vine that blooms almost year round, attracting hummingbirds, butterflies, and many other beneficial insects. Grow it as a groundcover, let it climb an arbor or trellis, or train it to cover a fence. You’ll be rewarded with blooms from spring to fall, and I’ve even seen blooms on mine in December! It will grow in sun or shade, but flowers more profusely in full sun. 

For the shade, try Lobelia cardinalis, our native red Cardinal Flower, loved by hummingbirds. This perennial prefers moist soil, but can be grown in regular garden soil with supplemental water. 

If you have a woodland garden, try the beautiful Plumleaf Azalea, an American native azalea made famous by Callaway Gardens. Rhododendron prunifolium is a rare deciduous azalea with bright red blooms in late July and August. Plumleaf Azalea prefers a cool shady spot with regular water. 

Perennial hibiscus continues to offer up showy blooms in several colors right up until the onset of cold weather. 

And for a little later on in the season, consider adding Swamp Sunflower, a good companion for perennial hibiscus, since they both share a love for sun and water. Helianthus blooms in September with large, bright yellow flowers on tall stems up to 10 feet tall! 

I hope you’ll try some of my suggestions in your late summer garden as you strive to make your garden more beautiful year round.

July Blooms in my Georgia Garden: Surprise Lily, Lycoris Squamigera

A late-blooming flower you'll probably see only in the South is the old-fashioned favorite, Lycoris.

Lycoris squamigera in July

Lycoris squamigera, is usually referred to as Surprise Lily, but a funny common name for this plant is Naked Ladies. Surprise Lilies blossom in the middle of summer, usually sometime after the 4th of July. The bulb lies dormant a good portion of the year, and then suddenly surprises us by sending up a naked flower stalk up to 2 feet tall, topped with very fragrant pink trumpet-like flowers that look somewhat like a cluster of amaryllis. It is in the amaryllis family. Leaves do not emerge until the flower stalk has faded. The trait of having a flower stalk with no foliage at the bottom is the reason for the amusing common name "Naked Ladies." Leaves are strappy medium green leaves like you'd expect from a lily, but by early Fall they turn yellow and disappear again.

Probably because it grows from a bulb, Lycoris squamigera is very easy to grow. Growing equally well in sun or shade, Lycoris is very versatile and is at home in any southern garden. However, you can grow this one even if you live in a colder climate, since it is hardy in USDA Zones 5-9. Squamigera is the most cold hardy of all Lycoris.

Surprise Lily is not picky about soil. Whether you have clay or sand or even the very rare "good soil," Lyoris squamigera will thrive and multiply. It doesn't even matter if your soil is acid or alkaline.

Lycoris squamigera will appreciate regular water during the growing season, but it's just not necessary. And once it goes dormant and the foliage has disappeared, it needs no water at all.

Hot Georgia Summer Takes a Toll on my Garden

For the last several weeks, temperatures have reached 98 or above each afternoon, and with, most of the time, not a cloud in the sky! This climate can sure take a toll on garden plants--even those famous for loving hot, dry sun. In the last week I've noticed that even the butterfly bushes and lantana have wilted in the afternoon heat. That observation prompted me to get my ice water and take a walk through the garden looking for the tough guys. I thought I'd share with you my findings.

Plants not wilted in my garden today:

• Arizona Cypress
• Bamboo (where did that come from?!)
• Cactus (if that ever wilts, I'll quit gardening!)
• Eucalyptus
• Holly
• Hosta
• Loropetalum
• Mahonia
• Redbud
• Rosemary
• Spirea
• Yucca (lol, you know that will never wilt!)

The plants mentioned above are in parts of the garden not irrigated. The only water they receive is what falls from heaven. As a native plant pusher, I was appalled to see that most of the non-wilted varieties are from foreign lands! It pains me to say that, but I will ponder on it, figuring that perhaps I need to do some research. This part of the country has been prone to heat and drought way longer than I've been gardening. Native plants have learned to deal with this weather much better than I have. So I'll be stepping out in the heat to tour some local gardens I know to be native plant sanctuaries. I'll have my notepad in hand, and I'll let you know what I find.

Clethra Attracts Hummingbirds and Butterflies to the Garden in Summer

If you're lucky enough to have a moist spot in your garden, consider Clethra alnifolia. Clethra is also known as Summer Sweet or Sweet Pepper Bush.

Blooming in the middle of the hot summer is enough reason to name it Summer Sweet, but I think that common name derives from either the sweet fragrance or the sweetness of the nectar. Butterflies, hummingbirds, and other pollinators love it as much as you will, and they'll appreciate you for planting it in your garden.

Once the blooms fade, dark black seeds are visible on the tips of the stems, hence the other common name Sweet Pepper Bush.

There's a Clethra suitable for just about every garden, since a variety of types are available.

• Ruby Spice has rosey pink blooms on a large growing shrub up to 10 feet tall.
• Hummingbird has white blooms on a more compact plant around 3 feet tall. This is the one seen growing around Hummingbird Lake at Callaway Gardens.
• Sixteen Candles 6 inch long white flowers on a tidy shrub about 4 feet tall.

All Clethra varieties are very fragrant, reminding me of fresh honey.


Clethra is easy to grow, but does need regular water. Perfect around a pond or stream, but you can grow it right in your garden as long as you can water it weekly.


Clethra grows well anywhere in USDA Zones 4-9.


An added bonus is that Clethra displays lovely yellow foliage in fall!

Getting the Garden Ready for a Hot Georgia Summer

Gaillardia at Shady Gardens Nursery

Getting the garden ready for a hot Georgia summer can be easier than you think! 

 

Plant selection is most important—choose plants you know will thrive in your area. Planting trees, shrubs, and perennials native to your climate zone means less work for you, because native plants are accustomed to the difficult conditions our Georgia summers offer. They are better able to withstand our drought, and some native plants even prefer our muggy, humid temperatures! 

 

Always amend the soil with compost or composted manure. Plants are better able to tolerate harsh conditions when they have good soil to live in. 

 

Don’t overlook the importance of mulch.  Apply a thick layer of organic mulch such as straw, bark chips, or shredded leaves to conserve moisture, keep the plant roots cool, and prevent weed growth. Gravel mulch is not suitable for our climate, except in a cactus garden, because it heats up too much in the summer. 

 

Finally, if your budget allows, install a soaker hose or drip irrigation watering system. This will get the water down to the roots where it’s needed with less water waste.
