I just discovered them this year, and LOVE them!!! I bought a blue/white only mix at a nursery, but have seeds saved from the blue/white/pink mix that I planted this year. Will definitely use next year. Too bad they are a short-lived annual...but the seedpods are attractive for a long time.
Course, maybe I should have done something to them to make them last longer? Dunno. At any rate, yes, loved them tremendously!

I've haven't planted any new Nigella for a few years now; it just keeps reseeding for me. It is too bad that they're so short lived; they're so pretty. If worse comes to worse, you could always dig up your plant when frost time comes nearer, with as much soil as possible, and bring it indoors, to get some seed. I did this with a salvia last year...

Yes, this is a good plant. Self sows well. Needs no care. If you had one and it dropped seeds, most likely it will be back in the general area...they do move around some.
I had majority of blooms in May. But one plant sprouted in August and flowered thereafter.
On the West coast, in the Fall, just fling your wildflower seeds out where you want Spring flowers. The rains generally will do the rest of the work for you.

thanks everyone I hope it lives throw the winter or there are some seeds left to grow in the spring, I have thought about bring it in but I think it needs full sun and doubt it will have time to bloom before frost or have enough light to bloom if I brought it in.

The seedlings are very winter hardy. They survive the Chicago winter. You won't have any problem overwintering them outside in Oregon.

I haven't had to plant them in 5 years...they re-seed like mad for me. Most of the re-seeders come up in late fall and winter over right along with the larkspur re-seeders :D
Here's just a few pic....
The first two were from June 16th and the 3rd July 2nd...

Nigella hispanica - They self-seed here in zone 2b too.

Sharon

I know that you are in the Pacific Northwest, which is quite different from where I live, but it might help you to know that we sow the seeds here in the fall, they come up and sit there all winter and then bloom in the spring. Maybe you will get lucky and your volunteers will make it through for you. If not, the seed is easy to find.

Well I am in the Inland Northwest and they self-sow in my garden right about now through next month and winter over as little plants.
Juanita, I love those white/pink ones too and Sharon I've GOT to try that species!!!

Vera

These are so cool. They reseed nicely in my zone 5 garden ... and just sort of pop up here and there. One of those flowers I don't mind "volunteering" wherever it wants.
