Tian Men Dong seeds (Asparagus cochinchinensis)

LATIN NAME: Asparagus cochinchinensis

COMMON NAME: Tian Men Dong

Plant Profile

Known to gardeners as Tian Men Dong, Asparagus cochinchinensis is a noteworthy species. Through the flowering season it keeps visiting bees well supplied. Taken as a whole, it is a plant that repays a little attention many times over.

Science & Biotechnology

The species features in the wider study of the Asparagus group, and its traits make it a useful subject for work on germination biology, cultivation and ornamental selection. This combination of deep classical use and ongoing research interest makes it one of more actively studied tuberous roots in the traditional Chinese herbal pharmacy. From a research perspective, species of this kind are valuable material for work on propagation and on the selection of uniform lines.

Uses & Benefits

Beyond its ornamental appeal, Tian Men Dong has the practical versatility that makes a plant worth growing from seed year after year. Tian men dong tuber remains a significant ingredient in traditional Chinese herbal formulas today, and as with any medicinal herb, appropriate use is best discussed with a qualified herbalist or healthcare provider. As a climbing ornamental, its fine, feathery foliage also gives it some appeal for a wildlife or specialty medicinal plant trellis. It takes hold quickly and asks for no special treatment from then on.

Asparagus is a tonic food in both Western and Chinese traditions: the tender spears supply folate and the prebiotic fiber inulin, while the root, Tian Men Dong, is a classical Chinese yin-nourishing herb. Its steroidal saponins are a continuing research subject.

Growing from Seed

Tian Men Dong grows readily from seed. Fresh seed benefits from a period of cold, moist stratification, after which it should be sown into a loose, well-drained mix. Bright, filtered light suits young climbing seedling well, and a support should be provided as it grows, since this species will scramble through nearby vegetation or trellising once established. Scatter the seed evenly over a loose seed compost, cover to no more than its own depth, and keep the pot moist and bright. Prick the seedlings out once they are large enough to handle, grow them on in bright light, and plant out when conditions allow.

Our Take

Tian Men Dong has real presence in the garden without demanding much in return. Young plants want steady water; older plants take conditions as they come.
