Marilyn I have from HCG Agastache 'Ava' and rupestris. Both are 5 years old and have survived through two moves. Love them. I also have Cana but it is from Bluestone Perennials. It is still my favorite.
I have Silene Regia from Praire Nursery. That is 4 years old. It has always struggled for me. But is alive and also has gone through two moves. Beautiful blooms!
