Dainty clusters of dark tipped, yellow or orange trumpet flowers, above a mound of blue-green ferny foliage; an interesting focal point in the spring garden, bearing over a long period until early summer; goes dormant immediately after flowering
Siberian Corydalis has masses of beautiful clusters of fragrant yellow trumpet-shaped flowers with orange overtones and deep purple tips rising above the foliage from mid spring to early summer, which are most effective when planted in groupings. The flowers are excellent for cutting. Its ferny compound leaves remain bluish-green in color throughout the season.
Siberian Corydalis is a dense herbaceous perennial with an upright spreading habit of growth. Its relatively fine texture sets it apart from other garden plants with less refined foliage.
This is a relatively low maintenance plant, and should only be pruned after flowering to avoid removing any of the current season's flowers. It is a good choice for attracting bees and butterflies to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. Gardeners should be aware of the following characteristic(s) that may warrant special consideration;
Siberian Corydalis is recommended for the following landscape applications;
- Rock/Alpine Gardens
- Border Edging
- General Garden Use
- Naturalizing And Woodland Gardens
- Container Planting
Planting & Growing
Siberian Corydalis will grow to be about 16 inches tall at maturity, with a spread of 12 inches. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 5 years. As an herbaceous perennial, this plant will usually die back to the crown each winter, and will regrow from the base each spring. Be careful not to disturb the crown in late winter when it may not be readily seen! As this plant tends to go dormant in summer, it is best interplanted with late-season bloomers to hide the dying foliage.
This plant does best in full sun to partial shade. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is not particular as to soil type or pH. It is quite intolerant of urban pollution, therefore inner city or urban streetside plantings are best avoided, and will benefit from being planted in a relatively sheltered location. Consider applying a thick mulch around the root zone in both summer and winter to conserve soil moisture and protect it in exposed locations or colder microclimates. This species is not originally from North America..
Siberian Corydalis is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. It is often used as a 'filler' in the 'spiller-thriller-filler' container combination, providing a mass of flowers against which the larger thriller plants stand out. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden. Be aware that in our climate, most plants cannot be expected to survive the winter if left in containers outdoors, and this plant is no exception. Contact our experts for more information on how to protect it over the winter months.
