Stefan, they don't like clay soil too much, can you mix in some grit for your next try?
and a nice sunny patch, then let them get on with it.
Ronnie, a lot af alliums seed themselves to a point where you wish they'd stop
Some take longer than others to flower from seed and the giant flowered cultivars tend never to be as big in future generations
