| Habit: A Fast Growing Deciduous Tree |
| Habitat: Grows in woodlands in Japan but in China it is mainly found in open situations in rich moist soils at 1600 - 2800m[109]. |
| Height: 30.0 Width: 15.0 |
Cultivation Details:
Prefers a moist woodland soil in a position free from spring frosts[1, 200]. Tolerates some lime but it is probably best in an acidic soil[200]. Dislikes dry soils[200]. Succeeds in full sun or semi-shade[188].
A very hardy plant, tolerating temperatures down to at least -20°c, but it prefers a continental climate and can be excited into premature growth in the mild maritime climate of Britain when the young growth is then very susceptible to frost damage[11, 188, 200]. There is usually no lasting harm from this damage[188].
Rarely more than a bush in much of Britain according to one report[1] whilst another says that there are trees 18 metres tall in W. Britain[11].
A fast growing tree, it tends to grow with a number of stems[200].
Plants produce richer autumn colours when grown on acid soils, the fallen leaves smell like burnt toffee[188].
Plants in this genus are notably resistant to honey fungus[200].

Propagation Notes:
Seed - best sown as soon as it is ripe in a cold frame[200]. Sow stored seed in a greenhouse in late winter[78]. Grow on in the greenhouse for at least the first winter and plant out in early summer[200].
Layering in autumn. Takes 12 months. High percentage[78].
Basal cuttings, 15cm long, taken from May to July[200].
