Aesculus pavia: Red Buckeye Bloom in October!

Speaking of climate change, this crazy weather causes unusual phenomenon in the garden!

Take a look at the photo of our Red Buckeye Tree blooming today--October 16, 2009.

The Red Buckeye normally blooms in March here. This particular tree has a few other bloom buds getting ready to open within the next few days. I hope that doesn't mean it won't bloom in March, when I will be searching for signs of spring.

Native Azaleas: Plant Now for Spring Blooms & Fragrance

Native Azaleas are definitely a spectacular show in spring, but don't wait till Spring to plant them! Shrubs planted in Fall have a much better chance to get established and become healthy plants by next summer. 

The American Native Azaleas, species Rhododendrons, are deciduous, meaning they lose their leaves for the winter. This defoliation begins quite early in fall, depending on the climate conditions and the variety. Usually the earlier the bloom time in spring, the earlier leaf loss occurs in Fall.  

Fall is the best time to transplant shrubs because they are then dormant. Fall planted shrubs have all winter to become established before time to bloom and grow next year. This is especially important when your plants are received by mail, as is most often true with rare plants like native azaleas.

When planting native azaleas, soil preparation is key. All azaleas prefer well-drained soil. Amend the soil for drainage, especially if your soil is clay.  Prior to planting your native azalea, work in some compost or composted manure and shredded bark to the planting hole. To help insure good drainage, mound up the soil so your azalea is planted high. Be sure that the root collar is slightly higher than soil level so water will drain away when those heavy downpours occur.
 

When planning your native azalea garden, consider the site. Native azaleas naturally occur in the filtered light beneath large trees near stream banks, but will grow in full sun when water is adequate.  They perhaps will bloom more profusely in full sun, but need more water with more sun. 

Make sure you can get water to the plant if drought occurs. Native azaleas are quite drought tolerant once established, however, water weekly the first year or two, as the plant grows in to its new environment.  Also, the blooms buds are formed during late summer on the early blooming varieties, and if your area is prone to a late summer-early fall drought, pay attention to those weekly waterings, so you won’t miss out on your fragrant spring blooms! 

Finally, obtain some good organic mulch. Azaleas have a shallow root system. Apply a thick layer of any organic mulch such as shredded bark, leaves, or straw to conserve moisture and keep the roots cool. Never cultivate around your native azaleas, since this can damage those shallow roots. 

Once planted, your native azaleas will need water at least once weekly to insure good root development and beautiful blooms for years to come.

Fall Planting: Shubs that Will Flourish!

Fall is the best time to plant shrubs and trees. Our weather usually begins cooling off in September, making gardening easier on both the plant and the gardener! Although daytime temperatures are still hot, our nights are cooler. 

October is a great time to plant Azaleas, Blueberries, and Hydrangeas. This time of year just brings better weather for shrubs to establish themselves without having to fight for their lives! So if you dream of beautiful blooms covering your yard on shrubs like azaleas, hydrangeas, snowball bushes, etc, do yourself and your plants a favor and plant them now, instead of waiting until spring. If your dream includes eating tasty blueberries from your own garden, plant those now too! 

Since we are now receiving regular rainfall here in Georgia, you can take advantage of that and be ready to plant when another shower is headed your way.

Shrubs planted in fall will have a head start over spring planted ones, and will have a greater chance of survival during our heat wave next summer. Even though the top growth of the plant will be dormant and might not even have any leaves, the roots will continue to grow through the winter. So get out there and enjoy the beautiful weather we’re having!

Rhododendron colemanii: Red Hills Azalea Discovered Growing Wild in Alabama

Recently I learned of a newly discovered deciduous azalea native to Georgia and Alabama called the Red Hills Azalea. Rhododendron colemanii 'Red Hills' is a wild azalea that grows in the Red Hills region of South Alabama and eastward barely into Georgia along the Chattahoochee River. This newly discovered species is one of the tallest, most richly colored, and most fragrant of all the native azaleas. The late blooming flowers (usually May) can be any color from pure white to deep pink or even yellow or orange.

Red Hills azalea seems to prefer cooler bottomlands near creeks and streams. I'd suggest siting this plant in the shade of tall hardwoods and providing regular water.

Hibiscus Moscheutos: Hard to Believe it's a Native Plant!

We really do have some fabulous plants native to the Southeastern United States. Shown in the above photo is Hibiscus moscheutos 'Lord Baltimore' growing in our garden. Flowers are 8-10 inches across and look great with Black Eyed Susan, another native.

Hibiscus moscheutos is so spectacular that it's very hard for me to believe it's native to our area and not some tropical island. When I see it in full bloom, I wonder why some gardeners continue to add foreign plants to their gardens.

If red is not for you, these large-blooming hibiscus come in other colors as well. Lady Baltimore has pink blooms with a red eye. Her blooms might be even larger than Lord Baltimore.

Kopper King has smaller blooms, although still large, and reddish foliage which makes it appealing even when not in bloom.

Hibiscus enjoys moist, rich soil. You can grow it on the bank of a pond or stream, but these hibiscus grow equally well in a regular garden border. We water ours about once weekly.

Hibiscus moscheutos is available during the summer months from Shady Gardens Nursery.

Hibiscus coccineus: Texas Star

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.

Swamp Azalea: Rhododendron Viscosum

If you like fragrant plants, you'll want Rhododendron Viscosum in your garden! Most often referred to as Swamp Azalea, Rhododendron Viscosum is a native azalea found in the Eastern United States. Pure white blooms in early summer have a pleasing spicy scent reminiscent of cloves.

Swamp Azalea, as the name implies, is one of the few azaleas that can tolerate periodically wet soil. This plant can grow in regular garden soil, but it does not want to miss out on water. If you can water regularly when rainfall is absent, Swamp Azalea will be easy for you to grow in your garden. Grows very tall near streams.

Rhododendron Viscosum can be grown almost anywhere in the United States since it grows well in USDA Hardiness Zones 4-9.

Swamp Azalea can be grown in full sun if regular water is available. Otherwise, filtered sun/shade is best.

Marydel Azalea

Marydel Azalea is definitely one of my new favorites! Large bouquets of pink flowers fragrance my garden in April and May. We Georgians can't take the credit for this one--it was found growing naturally on private property which covered an area between Maryland and Delaware--thus the name 'Marydel.'

It is not certain whether Marydel is a naturally occurring cross between Rhododendron Atlanticum and Periclymenoides or just a pink-flowering form of R. Atlanticum, but Marydel is definitely a spectacular plant in any garden.

One might think that it would need cooler temperatures, since it grows naturally in the northeast, but Marydel has proven herself to be quite tolerant of our Georgia climate.

In addition to huge, beautiful, fragrant blooms in spring, Marydel's foliage seems to stand up well to our heat and humidity. Foliage attains a burgundy hue with the onset of our cold temperatures in late fall.

Try Marydel in your garden and you will not be disappointed!
