The genus is is a large one, containing some familiar weeds and many unknown treasures. We offer selected hardy species, with tubers. These are the best species for garden use, and never become weeds.
Most of our species thrive in a leaf-enriched loam out in the garden. Light shade is best, some will take sun. They grow in acid or lime soils and are seldom troubled by pests.
Corydalis can also be grown in pots, but it is important not to over-dry them in the summer, this causes shrivelling. The semi-desert and steppe species from central Asia are more forgiving in this respect than those used to cooler, moister natural habitats. These arid land species, from drier regions are often happier, in our climate, under cold glass or in the bulb frame.
Expensive species are not particularly difficult, but rather, they are slow to propagate. They do not divide or make offsets every year, others rarely set seed.
Order from Autumn list only.
