More Details

The best all round garden and flower arranging allium. 'Purple Sensation' starts to flower after the tulips in mid-May.

I'll pick flowers and then beautiful green bead-like seed heads until the end of July and I use them to decorate the tree at Christmas – simply cut them, then dry and spray silver.

No early summer garden is complete without a good drift of these.

Reviewed 27th May 2015 by Gudrun Berry

I couldn't resist the pictures in the catalogue, but was rather sceptical how this plants would fair at our wind-swept hilltop site with heavy clay soil. I shouldn't have worried - of the 15 bulbs planted, 12 came up and provided us with a long lasting, outstanding spectacle. They stood tall despite very stormy weather and provided interest even before they were in full bloom. As they are planted along a path it is impossible to go passed there without stopping and admiring them, noting every change and taking many photos of each stage of development at every possible angle!
