Uses

Material uses

A yellow dye is obtained from the unthickened bark[4][7]. The bark is a cork substitute. It is used to make buoys, floats etc[7]. The bark of this tree is not corky[1][3]. Wood - heavy, hard, strong, close grained. Used for furniture, the interior finish of buildings, utensils etc[4][7]. An oil obtained from the seed has insecticidal properties similar to pyrethrum[5]. (This use is for the closely related P. amurense. It might also apply to this tree[K].)

Propagation

Seed - best sown in the autumn in a cold frame[3]. Stored seed requires 2 months cold stratification, sow in late winter in a cold frame[8][2]. Germination is usually good. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the cold frame for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, 7 - 10cm with a heel, July/August in a frame. Pot up in autumn and over winter in a cold frame. Fair to good percentage[8]. Root cuttings - obtain in December and store in leafmold in a warm place for 3 weeks. Cut into 4cm lengths and plant horizontally in pots. Grow on in a warm greenhouse. Good percentage[8].

Cultivation

This section contains historical Plants For A Future notes marked noncommercial.

Prefers a moisture retentive well-drained deep rich loam in full sun[1][3]. Grows best in areas with long hot summers[3]. Plants are gross feeders and require a rich soil if they are to perform well[1]. Dormant plants are very hardy, but the young growth is liable to damage from late spring frosts[1][3]. This species is closely related to P. amurense, differing in its non-corky bark[1]. Dioecious. Male and female plants must be grown if seed is required.
