Along my driveway and right next to my
Piedmont native azalea sits
my Florida flame native azalea. And although orange and pink don't go together well from a design aspect, I love the fact that
these two azaleas sit side by side. Their blooming is pretty close together and in some years they are at peak simultaneously, but
I don't care. Since both are highly fragrant and the aroma is similar, I get a double dose.
In early April as their leaves appear, the Florida flame native azaleas will begin to bloom with large trusses of orange to
yellow 1-1.5 inch highly fragrant flowers with long stamens. This azalea's native range is along the gulf coast of Mississippi,
Alabama, Georgia and into northern Florida, so you will not see these growing wild in north Georgia as you would the
Piedmont native azalea, although it's just as hardy.
There can be some significant color differences within this species as shown below by the two mature specimen plants I've seen
around town:
Like the Piedmont native azalea, the Florida flame native azalea is easy to grow and is another good choice to begin to
learn the cultivation of native azaleas of which there are approximately 15 different east coast species.
Grow Florida flame native azaleas in morning sun or partial shade all day. They do need some sun in order to bloom but definitely
need protection from the hot afternoon sun. The soil should be rich in organic matter (not clay), loose and well-drained.
All native azaleas bloom on "old wood" developing their flower buds the summer prior to blooming.
The Florida flame native azalea is one of the most heat tolerant of the native azalea species.
Good companion plants include: hellebores, ferns, etc.
If you want to learn more about all of our native azaleas, check out this
excellent site by Donald Hyatt. It's the best
single site on native azaleas I've ever seen.
