Acer acuminatum aka Tapering Leaf Maple

Acer acuminatum is a deciduous tree in the Sapindaceae family. Its native range spans the western and west-central Himalaya and southern Tibet. Records include parts of northern India and Nepal. It grows in a temperate climate, despite its southern Asian range. In the wild, it occupies open ravines on shaded slopes. These sites lie at 7,900–10,800 feet [2,400–3,300 metres] above sea level. It is not native to Britain or Ireland.

Plants For A Future lists a height of about 20 feet [6 metres]. The tree sheds its leaves each year. Flowers appear from April to May. Each tree bears either male or female flowers, not both. Grow both sexes if you need seed. A lone plant cannot fertilise itself. The supplied species account gives no details of bark, leaf shape, or fruit. It also warns that this tree can be confused with Acer papilio.

This tree is described as easy to grow in cultivation. It prefers moist soil that drains well and a sunny site. It also accepts some shade, including light woodland shade. Sandy soil, loam, and heavy clay can all suit it. The listed soil range includes mildly acid, neutral, and mildly alkaline conditions. Plants For A Future gives USDA zones 5–9. A sunny woodland edge or a site with dappled shade suits its stated needs.

The leaves have a use as a substitute for tea. Plants For A Future gives its food value one out of five. The same source lists no known hazards, rather than proof of safety. It records no medicinal uses. Leaves can also surround stored apples and root crops to help preserve them. The wood is dense and fairly hard, but sees little use. The source does not flag the species as a weed.

Seed offers one way to raise new plants. Sow ripe seed in a cold frame without delay. It usually sprouts the next spring. Stored seed needs a 24-hour soak before a cold treatment. Keep it at 1–8°C for two to four months. Germination can take time. Pot up seedlings once they are large enough to handle. Grow them to at least 0.7 feet [0.2 metres] before planting in their final site.
