giant allium seed pods

On 06, Jul 2010 | No Comments | In propagation | By All Year Garden

How unearthly does that look! The “Giant Allium” does not only produce the well known beautiful purple globes, but after the flowers fade, it turns into this unbelievable spaceship seed. Don’t get overexcited though, the allium is done blooming mid June, and the seedpods don’t last long enough to provide winter interest. Another downer is that the flowers are either sterile or new plants are not coming true from seed.

That being said, though, it is a must in the perennial garden. The giant alliums come out faithfully year after year and if the conditions are good (at least part-sun and plenty of water), they will spread. You can dig them out and divide them in the fall to get more of these beautiful plats in your garden. They are completely care free, once you planted them and gave them a little bit of food, they will not need anything else. They are not disease prone and will not crowd your other plants. After the seeds are ripened, the plant dies back and will come back next spring.

This perennial grows up to 2 feet in height and about a foot wide and will provide food for the birds, bees and butterflies. Alliums are not scented, but the huge flower balls up to 8 inches in diameter are spectacular. Another plus is that squirrels don’t seem to have an appetite for the bulbs, so if you plant them in the fall, you’ll see them the following spring.

If you decide to try your luck and propagate the plant from seed, just let the seeds dry on the plant and store them in a brown paper bag in a place where they will not be susceptible to mold.

Come spring, plant in peat moss under a plastic or glass cover to contain the moisture. Good luck. If nothing else, you’ll satisfy your curiosity with respect to what can come out of those seeds. If you really, really want more of these beautiful plants, divide the bulbs.
