Main Bloom Time: Early spring, Late spring, Mid spring.Form: Rounded, Upright or erect, Vase.
Physical Characteristics
Acer palmatum is a deciduous Tree growing to 8 m (26ft) by 6 m (19ft) at a slow rate.
See above for USDA hardiness. It is hardy to UK zone 5 and is not frost tender. It is in flower from May to June. The species is monoecious (individual flowers are either male or female, but both sexes can be found on the same plant).
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils, prefers well-drained soil and can grow in heavy clay soil. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils and can grow in very acid soils.
It can grow in semi-shade (light woodland) or no shade. It prefers moist soil.

Edible Uses
Edible Parts: Leaves Sap
Edible Uses:
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[105, 177, 183]. 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. Leaves - cooked[105, 177, 179]. We have eaten nicer leaves[K].

Cultivation details
Landscape Uses:Border, Pest tolerant, Rock garden, Standard, Specimen, Woodland garden. Of easy cultivation, it succeeds in most soils preferring a good moist well-drained soil on the acid side and partial shade[11, 182]. Grows well in heavy clay soils. Chlorosis can sometimes develop as a result of iron deficiency when the plants are grown in alkaline soils, but in general maples are not fussy as to soil pH. Requires some shelter in the cooler areas of Britain and protection from cold drying winds[1]. Plants are hardy to about -25°c[184], but spring growth is subject to damage by late frosts[11]. A very ornamental tree[1], it is a polymorphic species[1] and there are many named varieties[11, 182]. Grows well with rhododendrons. Most maples are bad companion plants, inhibiting the growth of nearby plants[18, 20]. Special Features:Attractive foliage, Not North American native, Inconspicuous flowers or blooms.

Plant Propagation
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[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. Only strong-growing cultivars succeed from cuttings, plants of the dissected or variegated cultivars will rarely grow into good plants.
