Aquilegia ‘Munstead White' You could use any aquilegia they come in all kinds of colours and variations. They all self seed, not too much but quite a lot. Might be a nice one to grow with Edie as it germinates well and wouldn't disappoint. If you want it to keep looking the same year on year, only grow one type, they are promiscuous and will interbreed readily which usually means you end up with dull colours in the end. Mine are all dull now.
