Crimson Pirate is always on my underrated list. It also is always cheap, because it multiplies so well and is an older one I guess. I have just recently read that Crimson Pirate spreads by runners in some gardens (that would be a negative) but if it does in my garden I have not noticed it and the runners would have had to have been short. I have had many small clumps of Crimson Pirate (very photogenic by the way) and I have never had a problem with it being invasive, the new fans have always been close to the clump.
It has been around a long time, but it doesn't even have a rust rating in the database, It gets no respect! It is rust resistant in my garden, it is a bud builder in my garden, it reblooms, it blooms from early to late. It sends up lots of scapes also and is fertile both ways. It does earn a couple of prominent spots in my garden.
