Common Name: Three-Leaf Corydalis
Corydalis ternata is a perennial plant that can grow up to 0.15 metres tall.
It has medicinal uses.
Although no specific mention has been seen for this species, there is a report that Corydalis species are potentially toxic in moderate doses[
E. Asia - China, Korea.
Fields and low mountain slopes[
We have very little information on this species and do not know if it will be hardy in Britain. 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[
The tuber is anodyne and also stimulates energy and blood circulation[
]. A decoction is used in the treatment of stomach ache and abdominal pain, hernia-caused pain, poor circulation of blood and energy, body aches, headache, dysmenorrhoea, post-partum pain due to clots and traumatic injury pain[
Seed - best sown as soon as it is ripe, the seed rapidly loses viability if it is allowed to become dry[
]. Surface sow and keep moist, it usually germinates in 1 - 3 months at 15°c[
]. Germinates in spring according to another report[
]. Two months warm, then a cold stratification improves the germination of stored seed[
]. Sow the seed thinly so that the seedlings can be allowed to grow undisturbed in the pot for their first year. Apply liquid feed at intervals during their growing season to ensure they are well fed. The seedlings only produce one leaf in their first year of growth[
] and are very prone to damping off[
]. Divide the seedlings into individual pots once they have become dormant and grow them on in a partially shaded area of a greenhouse for at least another year. Plant them out into their permanent positions when they are dormant.
