Cultivation Details
Succeeds in a sunny position in any well drained soil of low or medium fertility[1]. Most species in this genus thrive in hot, dry soils[1]. Established plants are drought tolerant[2]. There are a number of named varieties, selected for their ornamental value[1]. The flowers are often used for dried flower displays[1]. If all the flowers are removed early in the season, the plant will often produce a second flush of bloom later in the summer[1].
Propagation
Seed - sow early spring in a cold frame[3]. The seed usually germinates in 3 - 9 weeks at 25°c[4]. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer. The seed can also be sown in an outdoor seedbed in mid spring and is then planted out into its permanent position in late summer or the autumn[3]. Division in autumn[3]. Root cuttings in the winter[1]. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-21. <temperate.theferns.info/plant/Echinops+ritro>
