Growing and Propagation

The plant grows to 10 inches high, doing best in part sun and in well drained but moist soil. The greenish flowers have a dark purple center but are small and relatively insignificant, and the tuberous roots are thick, growing to 3/4 inch in diameter. It can be propagated by seed, but is easier grown by stem-cuttings or root division.

Harvesting and Preparation

The root is dug and harvested in summer and fall. The small rootlets are removed, the main root is washed and then steamed until the center core of the root is no longer white. It is sliced and dried in the sun. Bai Bu is sometimes processed with honey (Zhi Bai Bu) by stir frying with 12.5 kg of honey to 100 kg of sliced root until it is no longer sticky to the fingers.

For medicinal use, good quality Bai Bu consists of large, thick roots. They should be grayish white in color and be soft and fleshy, without small rootlets.
