@William, I found your pic of Allium 'Ostara' and retrieved this thread. Is 'Ostara' a cultivar of Allium hollandicum or A. giganteum or a different species?. It reminds me a lot of A. 'Purple Sensation'. I'm trying to get the large Alliums established here. First I need to know more about what's being bred these days. Any suggestion of sources? TYiA.
