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.

Clethra: Pink or White Fragrant Bloom in Late Summer Attracts Beneficial Insects!

Clethra is one of my favorite native plants, but more importantly, it's a favorite plant of butterflies and other pollinators! Clethra alnifolia, better known as Summersweet or Sweet Pepper Bush, is another wonderful native plant that blooms in late summer. Obviously the common name 'Summersweet' comes from the very sweet-smelling blooms that appear right in the heat of the summer. The other common name 'Sweet Pepper Bush' comes from the attractive seed capsules that closely resemble Peppercorns.

The fragrant blooms which are 6-inch long spikes last for more than a month and attract many pollinators.

There's a Clethra for every garden, since this shrub is available in both large-growing and dwarf varieties. But when I say 'available' I realize that Clethra is truly difficult to find in nurseries. Why, I do not know.

My favorite is 'Ruby Spice' since I'm a fan of pink flowers, but the white-blooming 'Hummingbird' is much sought after, probably due to the beauty of the shrubs planted en mass around Hummingbird Lake at the famous Callaway Gardens in Pine Mountain, Georgia.

If your garden prefers a dwarf shrub, seek out 'Sixteen Candles'--a more compact plant that seems to have more bloom spikes than possible! The name was given to this plant by Michael Dirr because the upright bloom spikes really do resemble candles on a birthday cake. This plant is truly spectacular!

Whichever you find, you can count yourself lucky to have this plant in your garden. It requires only consistent moisture to keep it happy. (I'm sorry, I do know that consistent moisture is hard to provide in Georgia these days, but if you have a wet spot, a pond edge, a soaker hose, or even, as in our case, stopped up field lines because your wife didn't know any better than to plant a Weeping Willow in the wrong spot, this shrub is definitely worth the trouble!)

Of course, my favorite online source for native plants is Shady Gardens Nursery.

Fragrant Winter Honeysuckle Gets Me Outside in January!

Lonicera fragrantissima is an American Native Honeysuckle Shrub that blooms in winter, hence the common name, Winter Honeysuckle.

The blooms are small but very fragrant, and they simply cover the shrub in January and February, making walks in the garden eagerly anticipated on those warm winter days we often have here in Georgia. My shrubs are already covered with flowerbuds although we had very little rain here this year. Drought-tolerant and easy to grow, this native shrub should be in any garden if you have the space for it.

Winter Honeysuckle will develop into a large shrub and is hardy in USDA Zones 5-9. Red berries form in summer, but they're so well-hidden behind the leaves that they usually go unnoticed by all but the birds who seem to know where to look.
