April Blooms in My Georgia Garden: Week 2

Piedmont Azalea

Piedmont Azalea, Rhododendron cansescens, is a native azalea found in the Piedmont region of Alabama and Georgia. This plant has many common names. Piedmont means "foot of the mountain" which is where this native azalea is usually found. Hoary or Wooly Azalea is another common name, coming from the hairs in the tubes of the flowers. Sweet Mountain Azalea has to be because of the sweet fragrance of the blooms on this azalea that enjoys growing in the mountains. This shrub is often called Wild or Bush Honeysuckle, because the blooms look and smell like those of the honeysuckle vine. There are a few other common names which I cannot understand. But this is one plant that belongs in your garden.

Florida Flame Azalea

Blooms on the Florida Flame Azalea, Rhododendron austrinum, can be just as varied as those of the Piedmont Azalea. Flowers on the Florida Flame Azalea, as the common name suggests, are the colors of a flame and can be anywhere from pure yellow to pure orange, or anywhere in between. This one has flowers that are reddish orange and yellow. Florida Flame Azalea lights up the garden when in bloom. Although the native azaleas naturally occur in the shade of a woodland, Florida Flame azalea will bloom much more profusely when grown in full sun. By the way, although as its name implies, Florida Flame is native to the state of Florida, but you might not ever see it growing wild there. This deciduous Azalea is rare and endangered, so purchase it from a native plant nursery.

Lonicera sempervirens John Clayton

Our John Clayton Honeysuckle, a named cultivar of the native wild honeysuckle, Lonicera sempervirens, is showing out early too--ahead of the species known as Coral or Red Trumpet Honeysuckle.  The native honeysuckle is just as easy to grow as Japanese Honeysuckle, but it is not invasive, and this vine will not plant itself all over your whole neighborhood.

Viburnum Korean Spice

Viburnum carlesii Korean Spice blooms are beautiful--round flower clusters in the snowball arrangement consist of pink buds that open into white flowers with a yellow center. I wish computers had a "scratch and sniff" feature, because the Korean Spice Viburnum has a wonderful fragrance.  Like most viburnums, Korean Spice will grow very large over time, up to about 6 feet tall and just as wide. It is lovely at the back of the flowerbed or in a mixed shrub border. In Fall, the foliage turns a brilliant red and bright red berries develop. Here in Georgia, give this shrub partial sun, and it will grow very well for you.

Plant Azaleas in Fall instead of Spring!

Rhododenderon Canescens, Piedmont Azalea

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 pine 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.
