anyone have a source for ornamental alliums?

I have a neighbor down the street who planted some alliums. Bright purple ones. I am going to have to ask her if they are heirlooms or not. She ordered them on-line.

They are beautiful and I would love to get some to plant for next year. Another bonus I've noticed is that the honey bees spend a lot of time working the flowers.

Do they grow from bulbs like garlic, or seeds? Any sources to check into would be appreciated.

Thanks. maryinpnw
