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.

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!

Alabama Azalea

Lovely white blooms in April have a spicy lemon scent. The Alabama Azalea is native to East Alabama. A native plant rarely found in the wild, Alabama Azalea is is usually found growing in poor, rocky soil. The Rhododendron Alabamense is a hardy, drought tolerant native azalea that will grow well anywhere in the Southeastern United States.

Blooms are white with a yellow blotch. Too bad computers don't have 'scratch & sniff', because the blooms smell so good--kind of lemony and spicy!

Alabama Azalea is hardy in USDA Zones 7-9.

Florida Azalea: Rhododendron Austrinum

One of the brightest and showiest of all native plants in the spring garden is definitely the Florida Azalea.

Blooms appear in early spring and can be anywhere from bright yellow to a dark reddish orange. Rhododendron austrinum is deciduous so plant it among your evergreen azaleas and it will really stand out!

Blooms are very sweetly frarant, so you might want to plant one near your garden bench to enjoy as you relax.

As the name implies, Florida Azalea is native to Florida, but grows well anywhere in the Southern US and in zones as cold as USDA Zone 6.

Rhododendron Austrinum in on the endangered species list, so do not dig it up for planting in your garden if you find a specimen in the woods. Florida Azalea is propagated and sold by native plant nurseries, so you can purchase container grown plants for your garden.

Florida Azalea will eventually grow into a large tree-like shrub up to 10 feet tall. When found in the wild, it naturally occurs in woods beneath large deciduous trees, but flowers much more profusely when grown in full sun. Drought tolerant once established, but needs regular water to become established. Bloom buds on this spring blooming shrub are formed in late summer, right when we have our yearly drought, so water regularly during August and September to ensure good flowering in spring.

Let me know if you have trouble finding this plant in your area, because we have plenty! You can purchase them in our online store Shady Gardens Nursery.

Pruning Native Azaleas

As a native plant nursery owner, I'm often asked when should the Native Azaleas be pruned? Well, definitely not now, that's for sure! Many new gardeners mistakenly think all plants should be pruned in winter, but that's not so with most plants that bloom in early spring.

Azaleas and rhododendrons rarely need pruning anyway. I prune away only damaged or dead wood on azaleas. That should be done anytime damaged or dead wood is observed, to prevent disease.

Most of the native Azaleas bloom in spring, and they bloom on old wood. That means that the flower buds for this spring have already formed. Pruning now will remove those flower buds. If you need to control the size of your native azaleas or just want to shape up your plant's form, wait until after the blooms fade and prune then.

You Can Plant in Winter!

February is a great time for planting here in Georgia! Shrubs and trees planted before the arrival of hot weather have a much better chance of surviving the drought. I’m afraid it’s time we all adjust our gardens for the return of the drought each year.

Recently our garden was certified as a Wildlife Habitat by the National Wildlife Federation. We are very proud of that, because preserving our environment for wildlife and our children is very important to my family and me.

Not only is preserving wildlife and native plant species important from an environmental standpoint, but native plants are easier to grow, since they are able to thrive in our climate!

In addition to being easy to grow, many of our Native American Species offer other advantages over the imported counterpart.

Consider American Euonymus with the unusual red fruits instead of the more common Euonymus that is invasive. The fruit resembles a hard strawberry until the capsule bursts open to reveal bright orange seeds—food for the birds! (See the photo above.)

American Native Azaleas perfume the garden with a lovely fragrance, while Asian Azaleas have no fragrance at all! And what could be more beautiful than a native azalea in full bloom?

Nothing smells sweeter than the banana-pineapple scented blooms of the native Sweetshrub, Calycanthus floridus.

The bright red blooms of our American native honeysuckle vine, Lonicera sempervirens, will attract whole families of hummingbirds, yet won’t take over and pop up all over the community as does the very aggressive Japanese honeysuckle.

So as you add new plants to your garden during this great planting time, seek out some of these rare native specimens, and don't be afraid to plant them now, to give them a headstart before summer! And check back soon for suggestions on how you can improve your garden to help protect your local wildlife.
