Gardeners' Notes:

I live in North Central Texas and have alkaline clay soil that I minimally amended (just a bit of compost tilled in). My Autumn Rouge azalea's have done well for 3 years almost doubling in size although they aren't thriving here. They are planted on the north side of my house and only recieve a bit of dappled sun in the late evening and full shade the rest of the day. They bloom a little in the spring and well in the fall but they have not bloomed in the summer here. They are well worth growing even if you don't have the perfect site conditions.

There is a reason this was originally described as the developer's favorite. Great color, goes w/ most color schemes (neither purple or orange tint to the deep reddish pink). Nearly non-stop blooming from July till Frost and again in spring (sorry, not in May-June in zone 8). Nice rounded shape (less upright than Autumn Royalty). Takes full sun but faster growth in part shade.
