Cultivation Details
Cephalotaxus alpina is fairly cold tolerant when dormant, tolerating temperatures that can fall below -15°c. The young growth in spring however, even on mature plants, is frost-tender and so it is best to grow the plants in a position sheltered from the early morning sun[PFAF]. Prefers a moist well-drained sandy soil but succeeds in most soils though it dislikes dry gravelly or chalky soils[1, 2]. Prefers a position in semi-shade but tolerates full shade[3, 4] and it also succeeds but does not usually thrive in full sun[2]. It grows very well in the mild wet coastal region of W. Scotland where it succeeds even in full sun[2]. Requires a humid sheltered site[2], strongly disliking very exposed positions[1]. A very slow growing tree[5]. Plants are dioecious, but female plants sometimes produce fruits and infertile seeds in the absence of any male plants[3]. However, at least one male plant for every five females should be grown if you are growing the plants for fruit and seed. Plants have also been known to change sex[4]. Male cones are produced in the axils of the previous year's leaves, whilst female cones are borne at the base of branchlets[2].
Propagation
Seed - best sown as soon as it is ripe in a cold frame[6], it should then germinate in the following spring[PFAF]. A hard seedcoat can delay germination, especially in if the seed is not sown as soon as it is ripe[4, PFAF]. Stored seed should be cold-stratified and sown in a cold frame in the spring[2]. Germination can take 18 months or more. Prick out the seedlings as soon as they are large enough to handle and grow them on for at least their first winter under cover. Plant out in late spring after the last expected frosts. Greenwood cuttings of terminal shoots, mid summer to early autumn in a humid cold frame[1, 2]. Difficult[6].
