Gardeners' Notes:

Positive vossner On Mar 29, 2015, vossner from Richmond, TX (Zone 9a) wrote:

Planted in a low part of my garden, in full sun but protected by the canopy of a large oak tree. Has been a no care plant. I used packaged azalea & rhodie soil and kept it potted for 2 years. Then transplanted inground, amended the soil with the same mix, and it never skipped a bit. Great, easy plant. I've since added some other species azaleas, since they seem to do well with little effort. My FL Flame plant seems to be the all yellow form.

Positive coriaceous On Dec 27, 2014, coriaceous from ROSLINDALE, MA wrote:

With sweetly fragrant, showy flowers appearing on leafless stems, this is the first of the native deciduous azaleas to bloom in the spring. It is also one of the least cold hardy---some clones may not be hardy in Z6a (but some are).

The flowers come in a range of colors from yellow (most commonly) through orange to red. There are many cultivars and hybrids.

This can grow 8-10' tall in the south. Where winter hardy, this is said to be one of the easiest azaleas to grow.

Performs best on sandy, acid, well-drained soils.

I planted this 3 years ago in shade with only very late day sun and it has not bloomed yet....
I will move to a spot with more sun and check back...

I recently purchased R. austrimum 'Firecracker' with buds. It blooms before most of the leaves appear.

This azalea is native and is not nearly as fussy as my other azaleas have been. Has doubled in size in 6 months.
