About plant names...

Japanese maples are in fact Japanese in origin, occurring naturally in Korea and China as well. The low, mounded shape of the tree, along with its attractive color varieties and leaf varieties, have made it enormously popular throughout the world. Numerous cultivars are available.

Identification: These small trees do not exceed 25' (7.6 m) in height or width. Because they grow slowly, they often appear as rounded shrubs. Foliage may be purple or green. Leaves have 5-9 lobes, and are 1½-2½" (4-7 cm) around, with doubly serrated margins. Flowers are small, red or purple. Seeds are samaras ⅜-½" (1-1.5 cm) in size.

Acer palmatum (Japanese maple)

From left to right A. palmatum wild type, A. palmatum ‘Amoenum,’ and A. palmatum ‘Matsumurae’ (‘Dissectum’ is similar to ‘Matsumurae’). By Abrahami.
