They look great to me - except are they in a deep enuf container to grow as much as they'd like underground? I wanna grab that box and do some planting out!

If you want tidier Allium planting beds you can snip & eat some of the upper green...but when it gets really warm and leaves begin to die back, all energy in the leaves needs to to the bulbs. Let em flop - & die back.

I planted them out a few months ago; they haven't done much, but they aren't floppy!
