Hyacinth Bean ' Ruby Moon '

Lablab purpureus


Provides color all season.

Purple stems, lilac-rose blossoms, and shiny 2–3" magenta pods. While all parts of the plant are edible, we recommend boiling the mature seeds twice before eating. Used in Asian, Thai, and Indian cuisine. Blooms and pods are useful as cut flowers; pods may be dried. Also known as bonavist-bean, and lablab-bean. Tender perennial in Zones 9–10. Best grown as an annual elsewhere.

How to grow:

Successive Sowings:

Every 7 to 14 days up to 80 days before your average first fall frost date.


NOTE: In very hot summer areas, skip sowing as high heat approaches; temperatures consistently above 90°F will prevent beans from forming.
