Hi -- now that the garden is asleep -- I'm thinking ahead and realize I need some deep purple flowers to offset all the pink I have ... the only deep purples I have now are tall bearded irises and veronica speedwell sunny border blue (which is a great plant) and liatris which is not that dark ... I intend to try some lupines from seed again this year (but haven't had much luck with them) ... I'm also going to wintersow some blue false indigo ... any other ideas? Self-seeding annuals would be good too ... this is a part-shade bed that has a lot of the same color pink in it end of May/beginning of June ... what are your favorite dark purples?
