Worked out from 30 years of climate records for Rainbow. Microclimates vary: frost hollows and hills run later.
A tough, sunny cool-season flower with edible petals. It attracts hoverflies and ladybirds that eat aphids, and keeps flowering through autumn, winter and spring when little else does. A great partner for brassicas and salad greens.
