Which is best to grow if planting only a few plants?
Regarding Sunflowers, what is the difference between pollen and pollen less varieties?
Pollen less sunflowers are the ones you would grow for the flowers only.
" Pollen free types are excellent for cut flowers, they are uniform and vigorous in growth even under low temperature and short day conditions. Dense planting will provide quality cut flowers. Pollen free varieties can be sown September to March under glass and April to August outdoors. Min night temp 8°C day max temp 25°C require little or no fertilizer and water sparingly."
If you want the seeds, you'll need to grow the regular pollen-producing kind.
Reply:the only way one could be pollen-less is if it's a genetic freak (which is not necessarily a bad thing) and has what's called a double-flower. That is, instead of the smooth centre portion with ray florets (the petals) all around it, it would probably be one big mass of those petals.
Anyway, the pollen-less variety would not produce any seeds, and might be good is someone's allergies are irritated by pollen.
