heat tolerant perennials
I'm looking for a list of the most heat-tolerant perennials for this area. Last summer, as you know, was a scorcher and I want to be sure that any perennials I buy will be able to take the excessive heat (and possible drought). For instance, one source lists verbena as being heat loving, but another source stated that the only thing that stopped Homestead Purple from blooming was a week of heat in the upper 90s. Around here, a week or more of the upper 90s is almost a certainty. So, now I hesitate to buy Homestead Purple. What to do?
