What Is The Fastest Maturing/blooming Sunflower Species That Grows At Least 3-4 Feet?

Question

I’m trying to find a sunflower species or cultivar that grows and blooms much faster than other varieties. I live in zone 5 (iowa).

Answer 1

Generally, there is not much difference among growth rates, but if you want a slightly faster bloom, then you will want to choose one of the dwarf varieties.

Here is an article that will give some examples of different types of sunfowers:
