(Bishop's Goutweed, Snow-on-the-Mountain, Variegated Bishop's Goutweed)
Snow-on-the-Mountain is a rapidly spreading groundcover that is native to Europe and western Asia and has rampantly naturalized in North America. 'Variegatum' has three to nine widely divided, white and light green aromatic leaves that travel by way of fibrous roots and rhizomes. In mid spring to summer it produces umbels of tiny white flowers that turn to seed that will eagerly broadcast itself and freely germinate. (Removing seed heads when possible curtails unwanted volunteers from germinating)....

Grown for their architectural and often colorful foliage, aeoniums are evergreen succulent perennials or shrubs found mainly on the Canary Islands. They bear fleshy, spoon-shaped leaves in rosettes at the tips of one to several stems, with new growth appearing in late fall and early winter. Typically bright green to blue-green, the leaves are variegated, purple, or golden on some selections, and may have red-tinted margins. Many aeoniums are low mat-forming plants with short rosette stems; others...
(Aeonium, Kiwi Aeonium, Variegated Aeonium)
Its colorful foliage makes this low evergreen succulent a real stand-out in mild climate gardens. It may be a hybrid of Aeonium haworthii developed in Australia. Kiwi aeonium produces dense mounded rosettes of fleshy light green leaves that are chartreuse upon emerging in fall. The somewhat hairy, spade-shaped leaves have crimson margins and may develop pinkish variegation in cool weather. The rosettes are borne on short stems which root on contact with soil, resulting in a spreading mound...
An architecturally interesting succulent for garden color and texture, tree aeonium is a heat- and drought- tolerant native of Morocco. Its branched stems are upright, each bearing a tight rosette of spoon-shaped, bright green leaves. Some plants' leaves are mottled or blushed lightly with burgundy or purplish tones. In the spring, each mature rosette produces an upright stalk that towers above the foliage. At the top of the stalk is a dense mass of bright yellow flowers, each small and with many...

(Tree Aeonium, Zwartkop Aeonium)
A wonderful plant for color and textural interest, Zwartkop tree aeonium is a heat- and drought-tolerant succulent that originates from Morocco. The words "zwartkop" or "schwarzkopf" mean "black rose or head," referring to the dark leaf clusters. Its branched stems are upright, each bearing a tight rosette of spoon-shaped near-black leaves. A leaf is rich in very dark red pigments, making it look black from a distance. In the spring, each mature rosette develops an upright stalk that reaches above...

Easy to grow, this shrubby evergreen from the Canary Islands is prized for its handsome succulent foliage. It bears rosettes of fleshy light green spade-shaped leaves at the tips of branching knee-high stems, with new growth appearing in late fall and early winter. The leaves often have red-tinted margins. Where stems contact soil they will root, developing ever larger mounds with time. In spring, each rosette puts forth a large, single flower stalk topped with creamy yellow blossoms. The rosette...

Beautiful and fragrant white flowers, decorative nuts, and glossy leaves make the California buckeye one of the more interesting and pretty buckeyes for the garden. Native to the canyon hills and ranges of central California, this dry-season deciduous large shrub also boasts smooth silver-gray bark that arguably makes the plant look more stunning when no leaves are present.
The warmth of spring finds the new, light green foliage emerging, with hand-like (palmate) leaves with five to seven leaflets...
Yellow buckeye boasts pretty yellow and pink flowers, attractive fruit and nuts, and glossy, hand-like foliage that turns yellow and orange in fall. This tall deciduous tree is native to deep, rich, moist soils of the east central United States. Its bark is relatively smooth, with platy splotches of tan among drifts of light gray.
The leaves are palmate (hand-shaped) with five to seven lobes of glossy, dark green, long oval leaflets. On the tip branches in late spring are found clusters of rosy,...
Lobed, hand-like leaves and reddish-brown nuts distinguish the Ohio buckeye tree. This broad and round-canopied deciduous tree is native to low, moist soils of the east central United States. Its bark is gray and corky and wart-like when young, and fissured with age. It is among the first of the trees to leaf-out in early spring
The leaves are palmate (hand-shaped) with five to seven elongated lobes of bright green that deepens to dark green. On the tip branches in late spring are found clusters...
(Common Horsechestnut, Horsechestnut)
Horsechestnut is a tall, rounded, deciduous tree native to southeastern Europe. In spring, it bears showy conical clusters of large white flowers with yellow or pink markings. It later produces spiny fruits that contain inedible brown horse chestnuts. The large palmate (hand-like) leaves cast dense shade.
This sun-loving tree does well in moist, well drained soil, and tolerates salt and pollution. It makes an excellent shade tree, but beware of its falling nuts!.
