I have a single sunflower stem growing in a pot (12inch circumf, 8 inches deep) on a (largely sunny) deck area in the garden. it's now (late July) over 6 feet tall, but not really showing any sign yet of flowering? Does anyone know when flowers would normally appear? might it be to cramped in the pot for the roots and so that's preventing flowering? Thanks for any advice.
