Mine go from March to July. What might be choice August bloomers in zone
8, if I may enquire?

R. diaprepes (and it's hybrid), Polar Bear can bloom that late, but for the
most part it is to the native species azaleas you look for really late blooming
- prunifolium, viscosum, maybe an auriculatum or two.
The humble R. ponticum can extend past the end of July in some places, but
usually peaks in June.

Interesting. My viscosums are blooming now and tradtionally always have at this
time of year. What's up with that? Wouldn't mind if they bloomed as late as August
- there is always a lull in blooming shrubs at that time of year, compared to
spring.
