Before & After - Alliums

These decorative alliums (onions) are new to my garden this year, planted as bulbs last fall. They didn't get as tall as I expected, but perhaps next year. We'll see.

Alliums in various stages of bloom

After the purple flowers fade, these green orbs appear.

The green-headed orbs are beginning to lean as the stalks yellow. I cut one and it's doing well in a vase with other cut flowers. I'm wondering if with enough time the green orbs will develop into bulbs that can be planted. That would be rad given how pricey the large decorative alliums can be.
