Allium cyaneum

We've gotten this excellent small species over the years with various names attached such as 'Sky Blue' and 'Cobalt' and there is not a bit of difference between them. As a species, this is perfectly capable of standing on its own merits without the needless marketing ploy of a seductive name although there are differences in shades of blue but we have not had them. Small heads of dark violet blue flowers on 6" stems in June and July are held above dense clumps of fine grassy foliage. Easy and hardy clumper to zone 4 from China.
