I have a challenge. I have a difficult spot to fill and I need plant suggestions that meet very specific requirements. * small perennial plants or bulbs * zone 4 winter tolerance * heat tolerant * drought tolerant * able to be cut to the ground in winter * summer blooming * come in both pink and purple varieties * idiot proof/easy to grow It's been challenging trying to identify plants that will meet all of these requirements. Thank you! Amy
