Answer: There are many, many perennials that thrive in zone 7. I can't think of many that wouldn't thrive there as a matter of fact. Is there a particular perennial you are interested in or do you have a special requirement such as drought tolerance? Because there are so many that will work in zone 7, it would be easier if we could narrow the field a bit. Feel free to post another question via the website. All of the "basics" will work: Achillea (Fernleaf yarrow), Armeria (Sea thrift), Baptisia, Chrysanthemum coccineum (Painted Daisy), Chrysanthemum superbum (Shasta Daisy), Coreopsis, Digitalis purpurea (Foxglove), Echinacea purpurea (Purple Coneflower) and Rudbeckia (Black Eyed Susans). For the shade, consider Alchemilla (Lady's Mantle), Aquilegia (Columbine), Astilbe, Campanula (Bell Flower), Dicentra (Bleeding Heart), Filipendula (Meadowsweet), Tiarella (Foam Flower) and Heuchera (Coralbells).
