I've been getting a bit obsessed with annual sunflowers lately. Luckily I have a lot of land to plant all of the seeds that I've ordered. Hilarious! I've noticed that many of them are listed as pollenless, which is great for cut flowers. I just can't figure out how a company is able to provide massive amounts of seeds for a named variety of pollenless flower, if that flower can only be pollinated by a sunflower that produces pollen. The seeds from the pollenless flower would then be hybrid seeds, and wouldn't necessarily look like the plant that the seeds were growing on, if they are anything like many other flowers. I would think that it should be very reasonable to expect that the seeds would not come true. Is that correct? I suppose that all of the seeds are provided from clones, in order for the seeds to be supplied for sale. Or, maybe I'm wrong about that? Last year was my first year growing sunflowers, so I know practically nothing about them, other than I love them.

I've ordered a few pollenless varieties, only because they are pretty. I am not one to keep cut flowers in the house, but I do love collecting seeds! It will be interesting to see what comes from the seeds, if I get any, and if I'm able to grow them out next year. Have any of your grown seeds from pollenless sunflowers, and did you get anything totally different than the parent plant?

Hey Natalie. Heavens, it's a month since you posted this question and nobody replied? I am no help because I'm growing sunflowers from seed for the first time and I was just looking for a thread about sunflowers. It sounds like you're going to have to do your own research on this, or maybe ask the seed source people?

But I have a question - I planted a packet of decorative sunflowers under my birdfeeder because not much else will grow there - possibly all the sunflower shells are making the soil inhospitable? Anyway, my reasoning was that at least sunflowers will grow there so I went for it. They are growing like crazy, nearly 3ft. tall now but not branching yet. Since I'm growing them for flowers, I'd rather have more, smaller flowers than one big one on each plant. So is it ok to pinch out the growing tip to make them branch?

I was wondering if it's pollenless, how do they sell seeds to produce the same color? A hybrid using other sunflower pollen should produce something different, yet these seeds are the same color. Is there perhaps a pollen version only breeders have that is the same variety just with pollen?
