Pterocarya rhoifolia (common name: japanese wingnut)
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].
The leaves are aromatic when bruised[8].
Plants in this genus are notably resistant to honey fungus[7].
Range: E. Asia - China, Japan.
Habitat: Valleys and mountains all over Japan[9]. Wet areas along riverbanks and mountain streams in eastern Shandong, China[10].
Edibility: Seed[11]. No more details are given but the seed is very small and would be very fiddly to use.
Usage: Wood - light, soft, not easily cracked. Used for clogs, chopsticks etc.
Pollinators: Wind
Soil: Can grow in medium and heavy soils.
Seed Ripens: Mid Fall-Early Winter
Flower Type: Monoecious
