Hi Charithea - I envy you your success with Nigella/love-in-a-mist. I grow them under much the same conditions as the California poppies (inhospitable clay, not much water), but the Nigella look stunted. They germinate happily, but come to a halt (and flower) at about 20cm. I shouldn't complain, I always saw them as fillers while the shrubs got going.
