Isatis japonica
Propagation: Seed - sow spring or autumn in situ[1].
If the seed is in short supply then it might be better to sow it in a cold frame in the spring. Prick out the seedlings into individual pots when they are large enough to handle, and plant out in early summer.
Cultivation: We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it could succeed outdoors in many parts of this country. The following notes are based on the general needs of the genus.
Prefers a well-drained fertile soil in a sunny position[2][1]. Succeeds in ordinary garden soil[3].
Range: E. Asia - China, Siberia.
Habitat: Rocks, dry slopes, rock streams and sandy shores of rivers and seas[4].
Usage: A green dye is obtained from the leaves[5][6].
Pollinators: Insects
Habit: Biennial
Soil: Can grow in light, medium, and heavy soils.
Drainage: Prefers well drained soil.
Flower Type: Hermaphrodite
