I planted this mid-summer last year in a fairly dry area of my garden in a temporary location. I knew I wanted this variety and had to buy it before its intended bed was ready because it was the last Autumn Empress left at my local garden center. I tried to keep it watered in the temp location, but like every other busy summer gardener, I didn't take care of it as well I as I should have. It was wilted more often than it was turgid. I was pretty sure it would be DOA this spring, thanks to the additional stress from the brutal winter we had this year. No matter, though. I transplanted it a few weeks ago and it looks terrific. I wouldn't recommend treating your Autumn Empress as badly as I did last summer, but if you do, the little buggers seem to be rather tolerant of drought and abuse.

I have most of the Encores. This one has finer texture, but taller size. Definitely more upright than spreading. A bit slower to get established and 'take off'. Nice pink bloom, medium green foliage.
[ A. Carnival has similar flower and texture, but smaller, more spreading. A. Princess definitely more orange/pink and darker foliage w/ bronze fall color.]

I have not grown this plant myself, so I must give it a neutral rating. 'Autumn Empress', has an upright, thick growth habit (4 feet tall and 3 feet wide) with large deep, green leaves. It produces semi-double, deep pink 2.25 inch to 2.75 inch in diameter blooms. It starts to bloom a little later in the spring than do most azaleas. These new patented azaleas bloom approximately every three months (early spring, late spring, early summer, late summer, mid to late fall) until the first hard freeze. Some sources state that they bloom all year long.

It requires full sun with afternoon shade or light shade and well drained, slightly acidic rich soil. Shrubs planted after mid-July should not be fertilized until after the last frost. The developers of this azalea state that it is drought tolerant, but I have to see this to believe it. It is supposed to have a fast growth rate.

This plant sounds so good, I am going to buy one and test it out.
