On Vancouver Island... it is too late. Last year mine headed ok, but went mouldy before seeding because it was too late... that is, frost was not the problem, rain was. I'll see how things go this year.
Well, I don't know where you are. Here in SE Michigan, you can plant them now for flowers certainly. Seed might be iffy, but I personally gave up on that years ago, as the birds and squirrels strip them before a seed ever has a chance to ripen. Sown now, they'll be pretty in Sept. and into early Oct. Sunflowers tolerate some frost in the fall garden, but not a hard freeze.
