I am growing Summer Drummer allium for the first time and my husband cut the stalk back thinking they were spent tulips. Will they shoot up another stalk or are they done for the season? Thank you for any advice you can give.
No, they will not likely send up another flower shoot.
Allow them to die back naturally so they can still feed the bulb.
I understand the loss, yesterday my son mowed over a Hosta and broke off an entire Sedum while 'helping' me!
I try to think of the loss as an opportunity--to go back to the garden center!
