It did OK in partial shade at my last house. Can't remember when it started flowering - doesn't it say on the seed packet?

I would say like most annuals yes. Mine are in full sun as that was instructions on the packet. I have noticed when they self seed themselves around my garden its always in a full sun position.

If you are growing in low-elevation southern California, the seeds should have been planted in full sun last fall, and they should be blooming now. I'm not sure of the timing in colder climates.

Thanks for the reply.
I live in Northern California(SF Bay Area-SanJose).
The plant is nursery bought one, and the plant tag says FULL SUN.
Since my patio does not get FULL SUN, I am just wondering will partial Sun (2pm-5pm as of now) work for this or not.

sorry for the sideways photo!
have updated the Q with picture link.

I would try for at least 6 hours of direct sun. They tend toward powdery mildew, otherwise.

Thanks, Tugbrethil !
Will try to find a place where it gets at least 6 hrs of direct sun.
Does it grow any big? This one is in 4" pot now.

It depends on the variety. The mature height should be listed on the tag. Otherwise, if it says dwarf, expect 12-18 inches, if not, expect 24-36, maybe more!

I would add that the sideways photo shows a plant that looks very different to the Nigella I've grown. Are you sure that that is what you've got there? Would anyone else like to comment or try to ID it? They look a bit like carrot leaves to me, Nigella leaves are much thinner in my experience.

Since you added the photo I would say the same as Beattie it does not look like my Nigella. So I would plant it in a patio pot and see what happens.

Phew! I'm so relieved someone agrees with me. It was a bit of an "Emperor's New Clothes" situation.

I thought that too, but there are a couple of Nigella species and then varieties within it.

I do have it self seeded into some shadier areas but they tend to be more straggly and fowers are smaller.

Thanks for the reply!

Hope this turns out to be the real Nigella Damascena. [unless tagged wrongly]

Yes, will repot it to a bigger one.

I think it might be Nigella sativa, its foliage is more robust that N damascena.

looks more like Nigella sativa [black cumin] as it has a more robust leaf. also common name of 'love in a mist' with similar leaf and flower form.
