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.

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.
