I posted this some time ago, but the offer is still on, so I thought I'd repost. Alliums are gorgeous - perennials, i.e. plant once and they'll come up year after year (and increase in number). A lovely selection of different kinds as listed below:
These hugely popular flowers were a must-have at Chelsea this year and come in all shapes and sizes, from pretty Allium caeruleum (10 bulbs) and bushy, pompom sphaerocephalon (50 bulbs), to starburst aflatunensis (5 bulbs) and the unusual oreophilum (35 bulbs).
EDIT - the original link wasn't working properly (was charging a higher price) and so I've edited it. You'll now have to select the relevant offer when you go in to the site.
