I lov e the way radishes and Brassicas look when they flower.
And I grew an heirloom
yellow-podded snow pea from India with cool purple flowers ... but the pods were not sweet! At least not for me the only year I'll ever grow them. They had a mild flavor that was not "intensely green" like most snow peas. The vendor called the flavor nutty, but I would say starchy. Off my list for next year! Pretty, though. Big lemon-yellow pods and big, fancy purple flowers like a sweet pea. And 7 foot-tall vines.
