Is it too late to plant Allium's?

norma johnson

I planted 50 last October and had a wonderful display, my favourite being the Purple Sensation which was enormous.I saved the drying heads after flowering and they look really attractive in a vase. I ordered more this year (300 in fact) and have just received them so cant wait to plant them.Love Gardeners World mag and all its special offers for subscribers
