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.

A better-behaved cousin to the less-than-polite trumpet vine, cross vine is a colorful solution for a fence or arbor with afternoon shade. Although this east Texas native is slow to establish, ‘Tangerine Beauty’ sports brighter, showier flowers than other cultivars and will reward your patience with loads of orange blooms in both spring and fall.

Larger in all respects than common sweet pepperbush (Clethra alnifolia), this sizable shrub or small understory tree grows 8 to 12 feet tall and wide. In early summer, long, slender racemes composed of small ivory flowers appear, then give way to peppercorn-shaped seed capsules that swoop out from the branch tips in fall. About the same time, lance-shaped leaves become a glowing golden yellow before falling to reveal the reddish brown bark. The bark peels in small, irregular patches in the fashion of sycamores (Plantus occidentalis) to expose a dusty gray under-bark. Cinnamon clethra is a good choice for a woodland garden, where the tiered branches and elegant stems look captivating against new fallen snow.

Cosmos are branching annuals with ferny foliage and pink, crimson, or white flowers that work well in the back of a border. Although introduced in 1799, cosmos did not beome popular for the garden or as the subject of breeding efforts until the early 1900s. The rest is now history. The variety 'Sensation' won the All-American Selection Award of Merit in 1936 for its clear colors of pink and white, on early-blooming, 3- to 4-foot-tall plants. 'Purity' is the glistening white form of cosmos in the 'Sensation' series. 'Sea Shells' has quilled florets. The Sonata Series cultivars are dwarf plants only growing to about a foot or two tall.

'Husker Red' is one of the few penstemons that does well in wet winters and hot, humid summers. Ruby-toned leaves appear in spring, followed in late spring and early summer by 3-foot-high stems adorned by panicles of white blooms.  The flowers attract bees, hummingbirds, and butterflies, but the plants are not magnets for deer or rabbits. In autumn and winter, songbirds feast on the seed. For a stunning display, plant 'Husker Red' in groups. -Chris Kelley, Regional Picks: Midwest, Fine Gardening issue #120

Valued for its flowers, foliage, and fruit, Black Beauty™ elderberry is a deciduous shrub that requires regular watering during its first few yearsbut will become more drought tolerant as it becomes established. Areas with moist soil are ideal. Black Beauty™ will grow 8 feet tall if left unpruned, but fairly severe pruning in the first year will keep the plant from looking leggy. Pruning will sacrifice the large pink flowers, but the plant will be much sturdier and have a better habit if you do. The flowers, which bloom in June, are large and have a lemony scent. The foliage is dark and finely cut. Elderberries are edible and can be used to make juice or jelly, if the birds don't get there first. -Teresa Smith, Regional Picks: Northeast, Fine Gardening issue #120

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

'Postman's Pride' sedum is a wonderful dark-foliaged plant for sunny, dry locations. It has a semi-upright habit and produces masses of red to purple flowers from late summer through fall. The flowers attract honeybees and butterflies. Like other sedums, 'Postman's Pride' is useful in rock and xeriscape gardens because, once established, it thrives without irrigation except during severe droughts. Curious about the cultivar name? This plant was discovered by a Belgian postal carrier in his garden. -Ron Smith, Regional Picks: Upper Plains, Fine Gardening issue #120

This tall, sturdy prairie plant makes an imposing statement in the garden with its large, deeply cut leaves and yellow sunflower-like flowers that face east and bloom in late summer and early fall. The leaves of the compass plant can grow up to 18 inches long and are deeply incised with a shape that looks like something from a painting by Matisse. They align themselves on a north-south axis to conserve moisture by avoiding the midday sun. This plant requires a few years to enlarge and flower, but once its deep roots are anchored, it will live for many years.

A coarse but bold perennial giant for the back of the border with yellow, daisy-like flowers in summer.

Highbush blueberry provides four seasons of fanfare, starting with twisted, peeling stems in winter; profuse white or pink blossoms in spring; savory blue fruit in summer; and long-lasting foliage the color of a rich red wine in fall. The maroon to scarlet fall shades are effective for a solid month or more, as the leaves (especially in full sun) are reluctant to fall. The best fruit set occurs when you plant at least two cultivars that will bloom concurrently to ensure cross-pollination.

(Tall Verbena)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This outstanding annual or perennial deserves its popularity. It makes an architectural statement with slender, willowy stems that stand up to 6 feet tall and do not need staking. It then branches out widely near the top where rich lilac-purple flower clusters stand alone, as if they are floating. This Verbena makes a great see-through plant.

This tough, versatile plant requires little maintenance. 'Georgia Blue' is willing to grow in sunny or shady spots, puts up with excessive rain or drought conditions, and attracts butterflies with a low blanket of sky blue flowers from spring into summer. Small, dark green leaves turn glossy burgundy in winter. Use it in containers or rock walls, or as a companion groundcover to spring bulbs under trees.

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.

The needlelike leaves of these Profusion Series zinnas lend a soft textural feel that contrasts nicely with the glowing hot colors of the flowers. The vibrant flowers are about 2 inches in diameter, and the plants grow to just 12 to 15 inches tall and wide. Use them en masse in borders and beds, or plant them in containers. -Julia Jones, Designing with annuals, Fine Gardening issue #120
