The packet wastes no time on this: Ruby Moon is an ornamental, and its seeds are poisonous. That one fact decides where it goes — an arch or pergola away from the vegetable bed, pods left on the vine for looks rather than picked for the kitchen, and no casual snacking while you are saving seed. Do that and it is one of the best-looking climbers here, because the show does not stop when the flowers do.
Violet flowers give way to glossy, deep-purple pods that hang on well into the season, and the vines climb 10 to 15 feet with real vigor. It is a perennial in zones 9 and 10 and an annual everywhere else, so most of us are buying a fresh packet each spring. What we cannot vouch for is the sprouting: hyacinth beans wear a hard coat, results here are uneven, and the sensible approach is to nick, soak, and sow more beans than the arch needs.
One small thing we noticed and ended up liking: the packet is resealable and blocks light, which matters if you only sow half the beans this year. Leftover hyacinth bean seed keeps better in that pouch than in an open envelope in a shed.
Bottom line: We grow it for the arch, not the plate: violet flowers and glossy purple pods on a vigorous vine, with seeds that are poisonous if eaten.
