Corydalis Plants For Shade Gardens
Corydalis plants are plants for the discerning shade gardener. Lacy, elegant foliage and bright blossoms make these perennial plants to go out of your way to find. Corydalis plants are close relatives of bleeding hearts, and you can see the resemblance in shape between corydalis flowers and small types of bleeding hearts. The genus name “Corydalis” derives from the Greek word ‘korydalis,’ which means crested lark, referring to the similarity between the flowers and spurs to a lark’s head. Corydalis is difficult to grow from seed packets, so most gardeners will purchase transplants from a nursery. It should go in the ground in fall or early spring in a bed of loose soil enriched with compost. Good drainage is essential.
Weekly irrigation and removing spent flower stalks are the main tasks with corydalis plants. In midsummer, the plants can be cut back to stimulate a second flush of flowers. In climates where it grows as an evergreen perennial, it’s a good idea to cut it back about 50 percent in late fall to encourage full, compact growth the following season. Maintaining a layer of mulch is a great idea to keep the roots cool, conserve moisture, and discourage weeds.
