Hi June, your post was so informative on plants that tolerate dry conditions. Thank you for sharing. I live in South Central Pennsylvania and our climate has changed over the past 3 decades from one with hot wet summers to one with hot summers with an almost invariable dry spell that lasts from 3 weeks to 2 months...we're moving in the direction of an almost Mediterranean climate it seems. I am desperately trying to find perennials that will tolerate these dry spells without supplemental watering. Your list is invaluable! I am especially intrigued by the foxgloves. I happen to love the looks of D. ferruginia, but always assumed these are plants that need a lot of water, damp ground. So that's one I'm definitely ordering seeds for!
Thanks, good gardening, and hope some major rain soon falls your way. Annie
