Indigofera pseudotinctoria Matsum is a hardy deciduous shrub from the pea family. It blooms with dense clusters of soft pink flowers in summer, attracting pollinating insects. As a nitrogen-fixing legume shrub, it can improve poor soil naturally. Its seeds have a hard seed coat, which inhibits water absorption. Hot water soaking treatment helps break seed dormancy and raise germination rate.
It grows well in warm temperate and subtropical zones. Widely distributed across central, eastern and southern China. It fits USDA hardiness zones 6 to 9. It tolerates cold winters, drought, rocky slopes and slightly acidic barren soil.
Ecological Value: Nitrogen-fixing roots boost soil fertility. Dense root network holds soil firmly to reduce landslide risk and control water erosion. It is a classic pioneer shrub for abandoned mines and degraded hillside restoration. Landscape Value: Graceful pink flower spikes add ornamental value. Suitable for roadside green belts and natural garden planting. Practical Value: The whole plant can be used to extract natural blue indigo pigment. It serves as good forage for livestock and provides nectar for bees and butterflies.
Store unused seeds in sealed, cool, dry and ventilated space. Keep away from high temperature and humid air. Damp conditions trigger mildew and reduce seed vitality. Seeds maintain good activity for up to 12 months under proper preservation.
Pack seeds with moisture-proof breathable packaging materials. Avoid heavy squeezing and crushing during transportation. Prevent rain soaking and high-temperature exposure. Keep the package dry and intact to guarantee seed activity after arrival.
Selected plump high-quality seeds with high purity and stable germination rate. Cold and drought resistant, excellent for mountain slope stabilization and soil remediation projects. Fast establishment and low maintenance after rooting.
