Castanopsis orthacantha

Propagation: Seed - requires a period of cold stratification and is best sown as soon as it is ripe in a cold frame[1]. 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[1]. Germination usually takes place within 1 - 3 months at 15°c[1]. 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[2]. Requires a sheltered position in semi-shade and a lime-free soil[1].

Although cold hardy in much of Britain, tolerating temperatures down to about -10°c, 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[3].

The seed takes two growing seasons from fertilization to maturity[4]. The catkins have an unpleasant hawthorn-like smell to attract midges for their pollination[5].

Range: E. Asia - S.W. China.

Habitat: Mixed and broad-leaved evergreen forests; 1500-3200 metres in W Guizhou, SW Sichuan, Yunnan[4].

Edibility: Seed - raw or cooked[6]. The seed, which is up to 15mm in diameter, takes about 18 months to ripen[4].

Pollinators: Wind, midges

Soil: Can grow in medium and heavy soils.

In Leaf: Evergreen

Seed Ripens: Mid Fall-Late Fall

Flower Type: Monoecious
