(Dwarf Wooly Yarrow, King Edward Yarrow)

Silvery-leaved, low-growing and drought tolerant, this is the perfect small yarrow for rock gardens and sunny border edges. A cross between the species Achillea clavennae and Achillea tomentosa, 'King Edward' forms a mat of narrow, gray-green, minutely toothed leaves. Loose, flattened clusters of buttery, pale primrose flowers bloom on short stems from late spring to midsummer. These are attractive to butterflies and have a soft, pretty appearance. Regular deadheading may extend...

(Giant Needlegrass, Giant Ricegrass, Giant Stipa)

Upright, graceful leaf blades of giant needlegrass create billowy tufts across the landscape. A cool-season perennial grass that often is short lived, it's native to the rocky and gravelly soils -- especially chaparral habitats -- from the Cascade Mountains of central California southward into Mexico's Baja peninsula. The root system is fibrous.

This bunching grass forms a V-shaped clump with airy, medium green leaves. Leaf blades are thin and held upright and occur in the moisture and cool...

(Chinese Gooseberry, Fuzzy Kiwi, Kiwi)

Kiwi are vigorous, deciduous, woody vines that are native to China. By fall, they develop brown, fuzzy, edible, egg-shaped fruits. These taste like tangy green grapes and have a green, juicy interior with a ring of small edible black seeds. Fruits are preceded by fragrant ivory to yellow flowers, and long, medium green, heart-shaped leaves cover plants throughout the growing season. Kiwi are dioecious, which means that each gender is found on separate plants, so gardeners need two plants, a male...

(Fuzzy Kiwi, Vincent Kiwi)

This is a large-fruited selection of a vigorous, deciduous, woody vine native to China. By fall, ‘Vincent’ develops brown, fuzzy, edible, egg-shaped fruits. These taste like tangy green grapes and have a green, juicy interior with a ring of small edible black seeds. The fruits are preceded by fragrant ivory to yellow flowers in spring. The leaves are heart-shaped and cover the twining stems through the growing season. The parent species is dioecious, which means that each gender is found on separate...

(Bishop's Goutweed)

Bishop's Goutweed is a fast-spreading Eurasian groundcover that has become naturalized across the whole of North America. It spreads via rhizomes (rooting underground stems) and has green compound leaves with three to nine leaflets. The equally weedy garden variety, 'Variegatum', is the most common form in cultivation and has leaves mottled with ivory.

In mid-spring to summer, goutweed produces umbels of tiny white flowers that are insect-pollinated and produce lots of brown seeds that spread...

(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)....

(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!.

(Baumann's Horsechestnut, Common Horsechestnut)

Long prized for its showy conical clusters of large white flowers with pink or yellow blotches, horse chestnut is a tall, deciduous, spring-blooming tree native to southeastern Europe. The cultivar 'Baumannii' produces exceptionally long-lasting, double, creamy-white flowers that age to blush-pink. It bears little or no fruit. 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. Baumann's horse chestnut...

(Japanese Horsechestnut)

Considered to have the largest and showiest of all horsechestnuts, Japanese horsechestnut's white blossoms in midsummer yield brown fruits with red-brown seeds; its fall leaf color is a brilliant yellow. A tall, spreading deciduous tree from Japan, this species is popular in China and is often confused with Aesculus chinensis. The dark sandy brown bark is relatively smooth.

The leaves of this horsechestnut get as large as a basketball. Each hand--like leaf is comprised of five to seven...

(African Lily, Blue Danube Lily-of-the-Nile, Lily-of-the-Nile)

The vigorous lily-of-the-Nile, 'Blue Danube', bears large rounded clusters of light violet-blue flowers on very tall stems. Often listed as a variant of the South African Agapanthus africanus, it is actually a hybrid. Where hardy, it is best grown in the landscape but in colder climates it may be maintained as a container specimen if provided a large spacious pot. Flowering is most profuse from late-spring through summer.

The long strap-like leaves of this tender perennial are medium...
