Spiny acanthus is a clump-forming, evergreen to semi-evergreen perennial native to southern Europe. It is a bold, old-fashioned perennial that offers tall spikes of interesting flowers of maroon and ivory as well as interesting rosettes of deeply lobed, coarsely edged, dark green leaves that look good through the season.

From late spring to midsummer it becomes topped with spikes of bicolored white and maroon-purple flowers subtended by dark green bracts. The flowers are very attractive to bees....

(Dieck's Maple)

A possible hybrid or selection of Norway maple, this fast-growing, medium-sized to large, deciduous tree is also sometimes listed as its own species.

(Maple, Norwegian Sunset™ Maple)

Norwegian Sunset maple is a rapidly growing, uniformly branched deciduous tree discovered as a chance seedling in a bed of Shantung maples (Acer truncatum) in Oregon. Its upright oval habit resembles that of its other suspected parent, Norway maple (Acer platanoides). This straight-trunked hybrid has glossy dark green five- to seven-lobed leaves that turn orange-red to red in fall. Small yellow flowers in spring give rise to winged green fertile fruit.

(Trident Maple)

Trident maple is an architecturally handsome small oval to rounded deciduous tree with lustrous, dark green, three-lobed leaves with blue-green undersides. They turn red, yellow, or orange in fall. New growth may be purplish or bronze. The flaking, multicolored bark of this East Asian native is also ornamental. Insignificant yellow flowers in early spring give rise to winged pale-green fruits.

Trident maple does best in moist, well-drained soils in full sun or partial shade. It is remarkably...

(Field Maple, Hedge Maple)

Tolerant of shearing, pollarding and hard pruning, hedge maple is a densely branched deciduous tree with excellent heat and drought tolerance. Historically, this slow-growing tree has been used to create large hedgerows along the roadways in its native Europe.

In early spring, small clusters of bright yellow-green flowers appear and develop into pretty dangling groups of samaras, or winged seeds to turn from light green to tan with a slight pink blush. The gently lobed, dark green leaves often...

(Dwarf Hedge Maple)

Hedge maple is a small and adaptable deciduous tree from Europe, western Asia, and northern Africa. The cultivar 'Nanum' forms a globular shrub of about a third the typical height, and its three-lobed leaves are smaller and paler. The leaves often have red-tinted margins in spring. The foliage turns an attractive golden yellow in autumn, before changing finally to brown. It sometimes persists on the stem into winter. The bright yellow-green flowers are sparsely if at all produced and result in few...

(Snakebark Maple)

One of a number of maples renowned for their handsome striped green bark, this small deciduous tree is native to Japan. Dense and spreading, it bears glossy, dark green, shallowly three-lobed leaves on red stems. The leaves turn dazzling shades of red and orange in fall. The trunk and older branches are purple-brown with green and white striations. New twigs are purple-red. Clusters of small chartreuse flowers in spring give rise to bunches of dangling winged red-brown fruits that are often borne...

(Cappadocian Maple)

A close relative of Norway maple that in many ways surpasses it as an ornamental plant, this small to medium-sized deciduous tree is found from eastern Asia to the Caucasus. In spring, clusters of small yellowish green flowers decorate the twigs, opening just before the showy purple-red new leaves emerge. The five-lobed leaves mature to glossy dark green. Broken leaf stems emit a milky latex. In autumn, the leaves turn rich golden-yellow. This tree has a gray, rough-barked trunk, and often produces...
