Collecting seed from Allium
I have about a dozen different allium, and while collecting the seed from drumstick and others is easy, I still can't figure out how to collect the seed from Globemaster or other tall "ball" type alliums. It's probably very easy and I'll laugh at myself when someone tells me. Do I cut the "ball" shaped bloom after it's finished it's cycle or do I leave it on the stem ? Thanks for any help.
