(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...
(Aeonium, Saucer Plant)
Imagine a plant that looks like it was squashed to the ground as if stepped on by an elephant. That's saucer plant. This strange low-growing tender perennial forms a flat, rounded rosette of succulent foliage. It is native to the coastal cliffs of Tenerife in the Canary Islands and is well-adapted to salt spray and high winds. Each rosette survives as a biennial or short-lived perennial, reproducing by seed or small pups that sprout from the base of the mother plant.
Spoon-shaped, bright green...
JC Raulston Arboretum at NC State University
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...

(East African Yellowwood, Fern Pine)
The graceful form of fern pine is accented by the linear, bluish green leaves that project from the branches much like the leaves of a lily. This tall, tender evergreen tree is native to higher elevations of subtropical eastern Africa. Unlike other conifers such as junipers, that have scale-like needles, fern pine leaves are smooth, flat and narrow, arranged spirally around gently pendent branches. Plants are dioecious, being either male or female. Male plants produce small, tan, finger-like cones...
(African Lily, Agapanthus)
Agapanthus is a small genus of some six species of tender or frost-hardy herbaceous perennials from temperate and subtropical southern Africa. They are grown for their summer display of showy violet-blue, purple or white flower clusters on tall stems.
These evergreen or deciduous perennials have attractive green strap-like foliage that grows from thick, fleshy rhizomes (underground stems). The rhizomes spread to form dense clumps. The dome-shaped, umbel-like clusters of flowers stand...
