Can be a dangerous and powerful depressant of the central nervous system and heart [301]. Avoid during pregnancy.

Cultivation details

Prefers a moist soil[1, 90, 200] but tolerates dry conditions during its summer dormancy[200]. Plants tolerate dry conditions and drought so long as there is plenty of humus in the soil[190]. Prefers a well-drained humus-rich soil[200]. Dislikes very acid soils[13]. Prefers a shady position, growing well on woodland edges[24, 90], but plants can also be naturalized in thin turf[200]. Plants seem to be immune to the predations of rabbits[233]. A greedy plant, inhibiting the growth of nearby plants, especially legumes[54]. The plant has a running rootstock and can spread rapidly when well-sited[4]. A very ornamental plant[1], there are several named varieties[190].

Propagation

Seed - best sown in a cold frame as soon as it is ripe in the summer[1]. Surface sow or only just cover the seed and keep the soil moist. Sow stored seed as soon as possible in late winter or early spring. The seed usually germinates in 1 - 6 months at 15°c[133]. When large enough to handle, prick the seedlings out into individual pots and grow them on in light shade in the greenhouse for at least their first year. When the plants are large enough, plant them out in the spring. Division in late summer after the plant dies down.

Despite the claim in ref.4 (Grieve 1930s/reprinted 1984) wood anemone does not spread rapidly even when ideally sited. In many areas of Britains it is considered an Ancient Woodland Indicator species- characteristic of which is its low rate of dispersal and spped of spread. Spread being typically quoted at 6 feet per century (Flora Britanica 0amongst many others).
