Common evening primrose - Oenothera biennis.This sweetly scented wildflower is a host for Sphinx Moth caterpillars. Adult Moths of many species will flock to the flowers-which can be a creamy lemon yellow,a soft pink,or white.I may be mistaken-but I could swear I've seen cultivars available in a pale lavender,too!For the Moon Garden,White,Pale Pink or White would probably show best.
