my sister grows them they had a yellow
flower that was very pretty and fixed me some kind of spicey dish with chicken& deer meat and had zuccinni& eggplant& artachoke with a tomato sauce that was spicey it was very good.i imagine was easy to grow she lives in TN but is real slow about answering e mail.I'd have better luck asking one of the kids..LOL
she did have it in a raised bed though.not much sun but is in sunniest part of yard is tucked around dianthus& zinnia,rosemary,thyme.said tasted better than store bought.that was in may.so can't tell ya a thing about
growing them
