I tried some Allium ostrowskianum this year. I had forgotten about them. The leaves looked just like the daffodils, and then was I surprised when they bloomed! They bloomed at a great "between" time when nothing much else was happening. I thought they were adorable. They were a hot pink color that was very distinctive.

The seed heads have dried. If I want increase, should I leave them on, or cut them? Do they set viable seed that I can scatter?
