Propagation

Seed - requires a period of cold stratification and is best sown as soon as it is ripe in a cold frame[3]. The seed has a short viability and should not be allowed to dry out. It can be stored for a few months if kept cool and moist (putting it in a plastic bag that is placed in the salad compartment of a fridge works well). Stored seed should be soaked in warm water for 24 - 48 hours prior to sowing[3]. Germination usually takes place within 1 - 3 months at 15°c[3]. As soon as they are large enough to handle, prick out the seedlings into individual pots and plant them out in mid summer if possible, otherwise grow them on in a cold frame for their first winter and plant them out in late spring. Give the young plants some protection from cold for their first few winters outdoors.
Cultivation

Prefers a good deep medium to stiff loam[1]. Requires a sheltered position in semi-shade and a lime-free soil[3]. Although cold hardy at least in the milder areas of Britain, this species really requires a warm continental climate if it is to prosper and it does not do well in the maritime climate of this country[5]. The seed takes two growing seasons from fertilization to maturity[6]. The catkins have an unpleasant hawthorn-like smell to attract midges for their pollination.
