Pale Corydalis FLOWERS Seed. Corydalis Sempervirens Caribbeangadenseeed.llc

An attractive biennial native for rocky, shallow-soil sites and cooler climates. Easy to start from seed, it has light to dark pink tubular flowers with yellow tips and greenish-blue leaves. Being a biennial, it will have basal rosettes at ground-level the first year and flowering plants the 2nd year. It could fill in any bare spot in a sun or semi-shade garden quite quickly. Also know as Rock Harlequin, Tall or Pink Corydalis, and Capnoides sempevirens, it is a member of the Fumitory family, like the similar-looking Dutchman’s Breeches. It is listed as endangered or threatened in several states. 

Growing your own plants from seed is the most economical way to add natives to your home. Before you get started, one of the most important things to know about the seeds of wild plants is that many have built-in dormancy mechanisms that prevent the seed from germinating. In nature, this prevents a population of plants from germinating all at once, before killing frosts, or in times of drought. To propagate native plants, a gardener must break this dormancy before seed will grow.

Seed dormancy can be broken artificially by prolonged refrigeration of damp seed in the process of cold/moist STRATIFICATION. A less complicated approach is to let nature handle the stratifying through a dormant seeding, sowing seeds on the surface of a weed-free site in late fall or winter. Tucked safely beneath the snow, seeds will be conditioned by weathering to make germination possible in subsequent growing seasons.
