Lathyrus davidii
Propagation: Pre-soak the seed for 24 hours in warm water and then sow in early spring in a cold frame[1]. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer.
If you have sufficient seed, then it can also be sown in situ in mid spring[1].
Division in spring. It may not transplant well so care should be taken[1].
Cultivation: An easily grown plant, succeeding in any moderately good garden soil but preferring a position in full sun[1].
This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[1].
Range: E. Asia - Japan, Manchuria.
Habitat: Woods and thickets all over Japan[2].
Edibility: Seed - cooked[3][4]. Some caution is advised, see the notes above on toxicity.
Young plant, including the inflorescence - cooked and used as a potherb or added to soups etc[3][4][5].
Pollinators: Insects
Soil: Can grow in light, medium, and heavy soils.
Seed Ripens: Late Summer-Early Fall
Flower Type: Hermaphrodite
