Veronicastrum sibiricum (common name: blackroot)
Propagation: Seed - sow autumn in a cold frame[1]. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer.
If you have sufficient quantity the seed can be sown outdoors in situ in the autumn or the spring.
Division in autumn or spring[1]. Larger divisions can be planted out direct into their permanent positions. We have found that it is best to pot up smaller divisions and grow them on in light shade in a greenhouse or cold frame until they are growing away well. Plant them out in the summer or the following spring.
Cultivation: Easily grown in a moderately fertile moisture retentive well drained soil[1]. Prefers cool summers[1]. Prefers a sunny position[2].
Range: E. Asia - China, Japan, Korea, Siberia.
Habitat: Grassy areas in mountains and lowlands[3]. Trailsides, grassy slopes and thickets at elevatins below 2500 metres in northern China[4].
Medicinal: The root is antimicrobial and hepatic[3]. It is used in Korea in the treatment of the common cold and as a liver tonic[3].
Soil: Can grow in light, medium, and heavy soils.
Flower Type: Hermaphrodite
