Summary

A perennial herb with hermaphrodite flowers pollinated by bees. Grows in light sandy to medium loamy, well-drained soils across a range of pH levels from mildly acidic to mildly alkaline. Tolerates semi-shaded woodland conditions and prefers consistently moist soil.

Description

A herb. It grows each year from seed. It grows 20-50 cm tall. It has a thin taproot. The leaves at the base have long stalks. Leaves are pale underneath. The leaves are D shaped and 5-9 cm long. They are once or twice divided.

Edible Uses

One report notes the plant is edible but provides no further details; this likely refers to the root.

Medicinal Uses

None known.

Known Hazards

Although no specific mention has been seen for this species, there is a report that Corydalis species are potentially toxic in moderate doses.

Distribution

It grows in temperate and subtropical plant. It grows on the sides of channels and stony places between 400-1,200 m above sea level. It grows in Sichuan and Yunnan.

Where It Grows

Asia, China,

Cultivation

We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it could succeed outdoors in many parts of this country. The following notes are based on the general needs of the genus. Prefers a moist, well-drained rather light soil, thriving in semi-shade. Grows well in a woodland garden or peat bed. Plants seem to be immune to the predations of rabbits.

Propagation

Seed is best sown as soon as it is ripe, as it rapidly loses viability if allowed to dry out. Surface sow and keep moist; germination usually occurs in 1–3 months at 15°C, though one report indicates germination in spring. Two months of warm stratification followed by cold stratification improves germination of stored seed. Sow thinly so seedlings can remain undisturbed in the pot for their first year, and apply liquid feed at intervals during the growing season. Seedlings produce only one leaf in their first year and are very prone to damping off. Once dormant, divide seedlings into individual pots and grow on in a partially shaded area of a greenhouse for at least another year before planting out into permanent positions while dormant. Division can also be done after flowering.
