Asparagus cochinchinensis (common name: chinese asparagus)

Propagation: Seed - pre-soak for 12 hours in warm water and then sow in spring or as soon as the seed is ripe in early autumn in a greenhouse. It usually germinates in 3 - 6 weeks at 25°c[1]. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in a sunny position in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer[K].

Division in early spring as the plant comes into growth.

Cultivation: Easily grown in any good garden soil[2]. Prefers a rich light well-drained sandy loam in a sunny position[3].

Plants are almost hardy in Britain according to one report[4], whilst others say that the plants tolerate temperatures down to between -10 and -15°c[2][3].

Dioecious. Male and female plants must be grown if seed is required.

Range: E. Asia - China, Japan, Korea.

Habitat: Near seashores all over Japan[5]. Thinly forested slopes, roadsides and waste fields from near sea level to 1700 metres in China[6].

Edibility: Tubers - cooked[4][7][8]. The tubers are up to 5cm long and 2m wide[6]. They are washed to remove the bitterness, the fibrous core is removed and the root is then boiled[9][10]. It tastes like asparagus[11]. Another report says that the tubers are eaten after preserving in sugar[12].

The fruit is said to be edible[12]. The fruit is about 6 - 8mm in diameter[2]. Another report says that the berries are harmful if eaten[3].

Medicinal: This species has been used in traditional Chinese medicine for over 2,000 years[3]. The dried root is antibacterial, anti-inflammatory, antipyretic, antiseptic, antitussive, diuretic, expectorant, nervine, sialagogue, stomachic, nervous stimulant and tonic[13][14][15][3][16]. It is taken internally in the treatment of fevers, debility, sore throats, coughs etc[3]. It is often decocted with other herbs and used in the treatment of a wide range of ailments including diabetes mellitus[15]. Prolonged usage is recommended for the treatment of impotence[15]. The root is harvested when the plant is dormant and is dried for later use[3].

The plant has a folk history for the treatment of cancer, modern research has detected antitumour activity and it is now being studied for the treatment of lung cancer[15].
