Description and Growing Information
Flowering Period
June
Cultivation
Chinese Wingnut grows quickly in full sun and moist soil, and is ideally located beside a stream or pond. The trees are tolerant of clay, wind, drought, and compacted soil once the trees have become well established. Any necessary pruning should be done in the summer to prevent the bleeding which occurs in spring or winter.
Shape
Pendulous branching
Growth

Habitat
Southeast China
Bark/Stem Description
The bark on the trunk is similar to P. fraxinifolia, but is smoother.
Leaf Description
The foliage is dense, though it can be thinned by pruning. The alternate deciduous leaves are pinnately compound, bearing odd numbers of elliptic-oblong pinnately-veined leaflets with serrate margins.
Fruit Description
The fruits develop in the summer on 2.5 dm long catkins, hanging from the distinctly differently textured green foliage. The fruiting catkins are frequently considered desirable from a landscaping perspective.
Propagation
Propagates readily from seed that has received approximately three months of cold moist stratification. Germination is epigeal and typically requires a little more than ten days. The first true (pinnately compound) leaves appear after the seedling reaches a height of ~6 cm. The young seedlings do well under half-shade and a temperature of ~18ºC (64ºF). P. stenoptera can also be propagated by cuttings.
