Plant information

Corydalis sempervirens, known by several common names, one being rock harlequin, is a low-growing biennial that is perfect for rock gardens (see, it's named well!) and border plantings. This plant produces clusters of unique, yellow and pink tubular flowers on upright stems. It thrives in sun to part sun in drier soils. Native to woodlands and rocky slopes in eastern North America, Corydalis sempervirens adds a pop of color to any shady garden setting.

stratification code
C(30)

A	Seed should germinate when sown in a warm location.
B	Hot water treatment: Bring water to a boil, remove from heat, pour over seeds, and soak for 24 hours.. Generally this is for seed with a thick seedcoat.
C	(# of days of cold moist stratification) Seeds germinate after a period of cold, moist stratification. Mix seeds with a handful of damp vermiculite or clean sand (moist—but not wet). Place mixture in a sealed plastic bag and store in a refrigerator, NOT the freezer.
D	Sow on the surface of the soil. Generally these seeds are very small.
E	These seeds need a 60-90 day warm, moist period followed by a 60-90 day cold, moist period.
F	These seeds need a 60-90 day cold, moist period followed by a 60-90 day warm, moist period followed by a 2nd cold, 60-90 day moist period.
G	Highest germination rate in cool soil.
H	Seeds need scarification: One way this can be achieved is to rub the seed between two sheets of sand paper. If code "C" is also called for, scarify first.
I	Legume Inoculant (more info next year).
J	Legume seeds (more info next year).
K	Parasitic species which needs a host plant.
L	Plant fresh seed or keep seed moist.
M	Best results when seed sown outdoors in the fall for a natural winter.
