Acer palmatum, commonly called Japanese maple, is a deciduous shrub or small tree that typically grows to 10-25' (infrequently to 40') tall. It is native to Japan, Korea and China. General plant form is rounded to broad-rounded, often with low branching. Each palmate green leaf (2-5" long) has 5 or 7 but less frequently 9 pointed toothed lobes. Small reddish-purple flowers in umbels bloom in mid spring (April). The flowers are rather attractive close up, but are not particularly showy from a distance. Flowers are followed by samaras (to 3/4" long) in pairs. Samaras ripen in September-October. Fall color includes shades of yellow, red-purple and bronze. Cultivars (often grafted) are quite variable.
'Shaina' has a bushy, tufted habit and will grow 4-5' tall in 8 years. Discovered as a witches' broom mutation on another Japanese maple cultivar ('Bloodgood'). Non-dissected leaves are clumped into masses giving a tufted appearance. Leaves are dark maroon during the summer, changing to a brilliant red in the fall.
No serious disease or insect problems. Subject to stem canker. Foliage tends to leaf out early in the spring and is subject to damage from late frosts.
Ornamental, understory dwarf tree grown primarily for its red foliage and interesting shape. Good specimen or accent around the home or yard or periphery of the border or rock garden. Group in the shrub border.
