Pterocarya stenoptera
Propagation: Seed - best sown as soon as it is ripe in a cold frame[1][2]. Pre-soak stored seed for 24 hours in warm water[1] then cold stratify for 2 - 3 months[3][2]. Prick out the seedlings into individual pots as soon as they are large enough to handle and grow them on in the greenhouse for their first winter. Plant them out in late spring or early summer of the following year[4].
Cuttings of half-ripe wood, July/August in a frame[2].
Cuttings of mature shoots, November in a frame. Only use vigorous shoots[2].
Layering.
Division of suckers in the dormant season[5].
Cultivation: Prefers a sunny position in a rich strong loam with abundant moisture at the roots[6][7].
Succeeds in areas that do not experience prolonged winter temperatures below about -12°c[7], but young plants and the young shoots of older trees can be cut back by winter frosts[6].
Plants are tolerant of compacted soils[7].
The leaves are resinous to the touch and emit a resinous aroma[8].
The root system of this tree is too invasive for small gardens[7].
Plants in this genus are notably resistant to honey fungus[7].
Range: E. Asia - China.
Habitat: Mixed deciduous forests on mountain slopes or riverbanks, often forming pure stands in small patches in the openings of deciduous oak forests, from sea level to 1500 metres[9].
Medicinal: Anthelmintic, astringent, febrifuge, stomachic[10][11].
The leaves are used in the treatment of abscesses, eczema and scabies[12].
The stem bark is anthelmintic and carminative[12].
Usage: The leaves have insecticidal properties[12].
Pollinators: Wind
Soil: Can grow in medium and heavy soils.
Seed Ripens: Mid Fall-Early Winter
