Acer palmatum N-O

Nuresagi (medium)
A vigorous, upright cultivar eventually making a spreading plant with deep purple-red leaves that hold their colour well into the summer. In spring, these have an opalescent sheen and in summer are lightly mottled with deep green. An additional feature is the fine white striation of the bark. In Japan, a completely different cultivar with green leaves carries this name.

O Kagami (medium)
Bright purple-red foliage in the spring darkens to a shiny black-red. The colour fades somewhat in late summer and changes to red and scarlet in the autumn.

Octopus (dissectum)
A vigorous cultivar with long, downward-arching shoots giving rise to its name. Leaves are a bronzy pink-red in spring darkening to plum-red and changing to copper-red in summer with contrasting green-tinged mid veins. Autumn colour is bright crimson red.

Ogi nagashi (small)
Long, slender-lobed leaves with jagged edges are a muted green in spring but later develop reddish-brown tips. Autumn colour is red and scarlet on a compact, twiggy plant that develops a lacy appearance over time.

Okina (small)
Narrow, deeply-divided and serrated leaves are bright pink in spring and gradually change to green with a red border. Wiry stems produce a dense, rounded, low growing shrub.

Okukuji nishiki (medium)
An upright twiggy shrub heavily variegated with cream on a powdery green background. New growth is tinged pink whilst some leaves will be completely cream with a pale green midrib. Red and rose-pink in autumn.

Okushimo (large)
A narrow, upright plant with a strong architectural shape. The green leaves are unusual in that the narrow lobes roll up to form a tube and give the impression of tiny three-dimensional stars held aloft by red stalks. Autumn colour is outstanding fluorescent yellow and gold.

Orange Dream (medium)
Spring colours of bright orange with prominent yellow midribs. Leaves later change to lemon-yellow with orange margins. Pale yellow in summer changing to bright yellow gold in autumn.

Orangeola (dissectum)
A small-leaved form with bright orange-red foliage in spring changing to reddish green with an orange flush in summer. A two-tone effect is produced with the orange leaves of the second flush which eventually change to dark red and fluorescent orange in autumn.

Oregon Sunset (small)
Long, narrow-lobed leaves are gracefully curved downwards and overlap each other on short stubby shoots. New growth is a soft light red changing to plum-red that darkens as autumn approaches, finally changing to a fluorescent sunset red.

Oshu shidare (medium)
The red counterpart of Omureyama with bright purple-red long-lobed leaves in spring and crimson in autumn. Pendulous branches grow out and cascade down producing a plant as wide as it is tall, giving the impression of a small, red weeping willow.
