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.

Care Tips Remember these are very perennial so plant them somewhere permanent. Removing the tatty foliage doesn't appear to affect the bulbs. Add grit on heavy soils. Potted Alliums can be kept in the pots and allowed to flower for their first season. Either sink the pots directly into the border or place into a larger container. Once they have finished flowering, feed with comfrey tonic and leave them to die back naturally in the pots, this will help bulk up the bulbs for next year. When the bulbs have completely died back, lift them and plant out into their permanent garden position. Alternatively you can plant out the pot grown Alliums from February to May before they flower. A root system will have established, so take care when transplanting into position and be sure the planting depth matches that of the pot.
Flowering May - June
Vase Life Add a drop of bleach to the water to minimise the oniony smell or change the water regularly. They will look good for up to 2 weeks without rearranging.

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!
