I planted gigantor sunflowers in my garden on May 30. They claim 110 days to maturity and that is pretty much right on as they are just now bursting at 116 days as the days cool and frost threatens. So it is my fault–I always think they will move more quickly for me.
I am bummed I won’t get to enjoy them too long. But I will enjoy them. Next year, I’ll start the seeds indoors in March.
