Cortusa is a small genus in the primrose family, Primulaceae, that bears a resemblance to primroses. Most species are spring flowering alpines native to mountains in S- and E-Europe, including the Alps and Carpathians, but a few species are native to China.
Propagation:
Division in spring.
Seed sown in spring.
Seed just covered and kept at 20°C (68°F) until germination. Germination can be slow and take several months. After germination it should be kept at a lower temperature with plenty of light so the plants won't become lanky.
Hardy and easy to grow. Tolerates a fair amount of shade.
