Alliums bloom in the late spring, so it's best to start growing them in the beginning of spring by spreading them out in the soil and covering them up with an inch of top soil. Learn about misting seeds to grow alliums with help from a sustainable gardener in this free video on growing alliums from seeds.
Hi, this is Yolanda Vanveen and in this segment I'm going to talk about how to grow Alliums from seed. Now these Alliums bloom in the late spring; now it's mid-summer and they've dried and they have lots of seeds on them. Right in the middle of this little heads, there's little black seeds. Now naturally, the seeds just fall as this dies back and then they'll regenerate and turn into their own bulbs. But you can actually collect these seeds and either way and start them the next spring or you can even put them right into containers immediately and then just leave them and they will generate for the next year. Now when you're starting them, you can take them right out of the little seed heads; the little black seeds or you could leave them contained within which it doesn't matter, they'll grow either way. An easy thing to do is just spread them out in your soil, whether it's container or the ground and then you just want to cover it up with about an inch of soil on top; so just barely cover them up and then kind of pat it down. Now the key is misting that soil real well. You don't want it to have a high pressure where the seeds are going to come out; you just want to mist it where it's really really moist and then that way you could have more Alliums and you can enjoy them every year from seed.
