Acer glabrum Rock maple Deciduous tree (1 Page of 5) The Acer glabrum plant species is found in Western N. America - Alaska to California, west to New Mexico. It is a member of the Aceraceae family. Common gardeners may know the plant as Rock maple. Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Acer glabrum Common Name: Rock maple Family: Aceraceae Author: Torr. Known Hazards: None known Mature Height: 9 Mature Width: Habitat: Edges of mountain streams, on rocks and in coniferous woods, 1500 - 2000 metres[82, 184].
Propagation Notes: 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. The seed has a hard coat and can be slow to germinate, often taking 2 years. 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[80, 113]. 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. It is very difficult to find suitable wood for cuttings.
