This cold hardy perennial is a very nice ground cover for shade because of its super long blooming time and dense habit, which blocks weeds under big trees.

Self seeding jolly plant that readily weaves its way among established plants. If you don't like where it lands, easy enough to pull out. Good companion for tall iris, where it will fill in below the iris blooms.

Use yellow corydalis in a shady rock garden or as an edging plant in a shady perennial border. The foliage is attractive through most of the growing season, and the flowers are pretty in small arrangements.

Bloom season is short, but I love the fine texture and bright green of the foliage. In my garden, it has nearly disappeared some years and self-sowed rampantly in other years. Shallow-rooted plants are easy to pull, and they transplant well for sharing also. If you're digging or pulling extra plants, even the ones that snap off at the base with little or no root will generally survive if you tuck them into a little pot of moist mix for a couple of weeks before planting out.

I've grown these for several years. Unusual yellow flowers. They are self sowing here though not profusely. They seem to prefer to sprout between the rocks edging my garden path, rather than in the nice soil where I thought I sprinkled the seed. They bloom in spring, then get a bit ratty while the seed pods develop and dry. Then in the late summer to fall I notice lots of fresh greenery. I am not sure if the old ones came back, or these are all the new ones. Either way, they are very fresh and green in the garden right now while everything else is frost-killed or brown. One note- the foliage has a pungent strange smell. You don't notice it walking by the plants, but you will if you collect seeds or weed it.

This is a very pleasant little garden plant that will happily self sow here and there if happy, yet the seedlings are easy to identify and remove if they are not wanted. Cheerful yellow blooms begin in early spring and continue in periodic waves throughout the summer. Very easy and perfect for a cottage garden.
