Allium atropurpureum 'Purple Sensation'

These worked really well against the pale green fence, a real focal point when sitting on the bench by the shed though became less striking the next year when the Lychnis grew up so fast.

I think there are about 5 plants here encircling the Eleagnus quicksilver. Also Allium sphaerocephalon in between them for later blooms. The Evening primrose grows behind and teh purple and yellow looked great together in 2010. As they pass over the Verbena Bonariensis comes up with a Thalictrum to soften the lines.
