Botanical Name: Acer palmatum var. dissectum AY-sir pal-MAY-tum variety dy-SEKT-um Common Name: Japanese maple, Threadleaf Japanese maple Synonyms: A. 'Dissectum' Genus: Acer
This round, mound-forming, deciduous Japanese maple has many qualities that make it an excellent garden plant, including a sculptural form, deeply cut foliage, arching shoots, and golden autumn color. The reddish purple flowers are tiny but attractive up close. They are followed by winged fruit. Threadleaf Japanese maple makes a beautiful specimen in small gardens and can be grown in large containers or used for bonsai.
Noteworthy characteristics: Finely cut foliage; golden autumn color; cascading habit.
Care: Needs fertile, moist but well-drained soil in sun or part shade. Only prune when dormant (late fall to mid-winter).
Propagation: Graft in late winter; bud in late summer. Sow seed in containers outdoors as soon as ripe or in situ. May be top-grafted to make bonsai.
Problems: Maples are prone to aphids, scale insects, and caterpillars. Verticillium wilt, tar spot, and other leaf spots and root rots are common. Late frosts may damage foliage in early spring.

(Tiger eyes sumac, Staghorn sumac, Velvet sumac)

Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Lemon-lime foliage, fuzzy stems, and intense fall color make this sumac cultivar a standout. It grows into an upright, rounded form about 6 feet tall and as wide. New growth emerges chartreuse. Fall brings leaves of yellow, scarlet, and orange. Flowers are yellowish green and followed, on female plants, by hairy, dark red fruit. This plant spreads by suckers and can be invasive. The species is native to North America.

Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This cross of the European smoke bush (C. coggygria) and the American smoke tree (C. obovatus) is a gem in the garden thanks to its multiseason interest. Its iridescent spring foliage is green overlaid with red; then its large pink clouds of blooms in summer are followed by brilliant autumn foliage that ranges from red to orange. 'Grace' combines well with just about anything; asters, ornamental grasses, and Japanese maples are good places to start.

This golden-leaved version of the southern paper mulberry can be treated as a cutback shrub to control size and for best production of brilliant golden yellow, large, lobed leaves. Or it can be allowed to grow into a small- to medium-sized tree. It's a most desirable garden plant and looks fabulous with deep blue salvias.

Vitex agnus-castus var. latifolia Vitex agnus-castus var. latifolia
(Chaste tree)
(2 user reviews)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Chaste tree is a southern favorite beginning to gain favor across the country. Whether left to grow as a large, multistemmed shrub or cut back annually for a more compact look, this selection is a winner. Fine, lacy leaves are glossy and green. Bright blue flower panicles begin to form in early summer and continue through the heat of the season and into fall. This is a reasonably cold-hardy, deer-resistant woody plant, and while V. agnus-castus is typically considered a Zone 7 plant, the variety latifolia can be grown in Zone 6 and even in southern areas of Zone 5.

Albizia julibrissin Albizia julibrissin
(Mimosa, Silk tree)
(2 user reviews)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

A large shrub or small tree, Albizia julibrissin is native to Iran to Japan. It is a fast-growing plant whose seedlings can become invasive. It can be seen growing in the wild in the southeastern U.S. and California in waste places, fields, and along roads.

However, its bipinnate, ferny leaves and fluffy pink flowerheads that cover the tree in summer make it a garden-worthy plant, as do the fragrance emitted by the flowers, which attract bees. Seed pods that resemble flat beans follow the flowers and persist into winter. Still, care should be used so that seeds from garden plants can't escape into the wild.
