WOW
I planted a single Suncredible sunflower in a 22" planter. It was very small with only a single bud when I received it, but by the end of the season it had not only filled the planter, but was spilling out about 18"-24" all the way around. A wind storm broke it in half and I thought it would die, but it didn't seem to even faze the plant. I would definitely recommend this as a landscape plant. It has been down in the 30s several times and still has blooms all over and has not been deadheaded 1 time.
