Herb: Hornbeam Maple
Latin name: Acer carpinifolium
Family: Aceraceae (Maple Family)
Edible parts of Hornbeam Maple:The sap contains a certain amount of sugar and can either be used as a drink, or can be concentrated into a syrup by boiling off the water. The syrup is used as a sweetener on many foods. The concentration of sugar is considerably lower than in the sugar maples (A. saccharum). The tree trunk is tapped in the early spring, the sap flowing better on warm sunny days following a frost. The best sap production comes from cold-winter areas with continental climates.
Description of the plant:
Habitat of the herb:Valleys and ravines in mountains all over Japan. Common in temperate deciduous forests, usually in moist sites along streams at elevations of 200 - 1300 metres.
Other uses of Hornbeam Maple:The leaves are packed around apples, rootcrops etc to help preserve them.
Propagation of the herb:Seed - best sown as soon as it is ripe in a cold frame, it usually germinates in the following spring. Pre-soak stored seed for 24 hours and then stratify for 2 - 4 months at 1 - 8°C. It can be slow to germinate. The seed can be harvested "green" (when it has fully developed but before it has dried and produced any germination inhibitors) and sown immediately. It should germinate in late winter. If the seed is harvested too soon it will produce very weak plants or no plants at all. When large enough to handle, prick the seedlings out into individual pots and grow them on until they are 20cm or more tall before planting them out in their permanent positions. Layering, which takes about 12 months, is successful with most species in this genus. Cuttings of young shoots in June or July. The cuttings should have 2 - 3 pairs of leaves, plus one pair of buds at the base. Remove a very thin slice of bark at the base of the cutting, rooting is improved if a rooting hormone is used. The rooted cuttings must show new growth during the summer before being potted up otherwise they are unlikely to survive the winter. Grafting is impossible for this species because no compatible rootstock has been discovered.
