Uses & Benefits
Sha Yuan Zi brings genuine presence to the garden and earns its keep across the growing season. Sha yuan zi seed remains a component of traditional Chinese herbal formulas today, and as with any medicinal herb, appropriate use is best discussed with a qualified herbalist or healthcare provider. Its low, sprawling growth habit and flattened seed pods also give it some interest for gardeners collecting unusual traditional Chinese medicinal plants. Routine care after establishment is refreshingly light.
Sha Yuan Zi, the seed of this astragalus, is a classical Chinese tonic for the kidneys and eyes, distinct from the famous Huang Qi root of its cousin.
Growing from Seed
Sha Yuan Zi is one of those generous plants that come along well from seed. Nick or lightly sand hard seed coat and soak it in warm water overnight before sowing into a loose, well-drained, sandy mix, reflecting this species’ preference for well-drained sandy soils in the wild. Full sun suits it well, and this low, spreading legume typically establishes without much difficulty once conditions are reasonably favourable. Sow the seed evenly over the surface and cover lightly, using a loose, well-drained seed compost, and keep it just moist in full sun until the seedlings are well up. When the young plants are big enough to handle, space them into pots or a nursery row and let them size up before their final move.
Our Take
Sha Yuan Zi, Flatstem Milkvetch has real presence in the garden without demanding much in return. Careful watering early on is rewarded by toughness at maturity.
