I would like to grow
I would like to grow sunflowers in smallish pots with school children to sell at their school summer fair on 14 June. When should we plant them (outdoors, London, UK) so that we have plants ready to sell by then? What type should we buy? Probably not giant ones - we don't want them to be enormous when we sell them, just big enough that people will pay a pound or two for them!
