Few plants evoke tropicalia quite like the Brugmansias, with their voluminous tubular flowers that drip from imposing shrubs or small trees. They look fantastic in containers or plunged into a border, and the dramatic display persists from late spring until autumn. In cooler climates, they may be brought under glass or cut back and held dormant in a cool basement.  All parts are highly toxic if ingested.

This clumping, drought-tolerant grass is one of the best pampas grasses you could grow. It has the showy, late-summer plumes common to this group, but they grow straight up, not willy-nilly like many other varieties; they eventually stand 4 to 6 feet above the foliage. Even better news is that this cultivar does not set seed, so it is noninvasive. The foliage features distinct golden edges, which, for a grass, usually menas that it loves shade or moisture. But 'Gold Band' tolerates heat and drought, making it great for large containers, and it can handle coastal conditions, too.

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.

If you dwarfed flowering raspberry (Rubus odoratus, Zones 3–7) and sent it to finishing school, Japanese wood poppy would be the result. Birders will note that Glaucidium is also the name of a genus of owls, and gardeners may, ahem, hoot and flap when they see Japanese wood poppy in full bloom. This debutant may need a year or two to refine before flowering, but when it does, the coming-out party is a show of violet sepals. (White varie­ties are also available.)

They begin blooming in February or March in a range of shades, adding much needed color very early in the season. The blooms last for a very long time, especially if the weather stays cool. Hellebores are tolerant of summer heat and humidity. -Marty Hair, Regional Picks: Upper Midwest, Fine Gardening issue# 127

A seldom-seen annual or short-lived perennial, this easy-to-grow plant performs as the perfect filler in beds and containers.

Oakleaf hydrangeas are already one of my favorite shrubs: They are tough and reliable; have great foliage, flowers, and fall color; and provide stems of dried flowers in winter.

Sprays of long, tubular buds spark into a fiery scarlet and fade to a pale cream on this annual climbing vine. A single flower holds tints of yellow, warm pink, orange, and red as if a watercolorist had laid down colors one layer at a time. As the bud matures, the colors wash away, leaving a pale blossom pushed open at the tip by protruding anthers. From a distance, the plant seems to be covered in hundreds of brightly lit candles. This vine also produces rich, bronzy-purple new growth which ages to a lovely deep green. The heavily indented, trilobed leaves resemble a hawk's strong wings, giving the plant the look of birds in flight. The foliage stays intact and healthy until frost. The bottom of the vine sheds its leaves as the season progresses, so disguising its bare base behind lower-growing plants is a must.

Generally speaking, daffodils perform best in full sun and well-drained soil, in areas where there is a fair amount of rainfall in the fall and spring and where the summer is relatively dry. However, cyclamineus-type daffodils seem to tolerate at least partial shade and more moisture than others do. Narcissus ‘Jack Snipe’ (pre-1951, Zones 3–8) is a charming example of this type of daffodil. Its white petals are swept back, as if it were standing in front of a fan, and its medium-length, buttercup-yellow trumpet (or nose) sticks straight out at a 90 degree angle from the stem.  ‘Jack Snipe’ is an intermediate-size daffodil, standing only 8 to 10 inches tall, and is perfect for a rock garden or the front of a flower border. This whole division of daffodils is becoming more popular not only because it tolerates some shade but also because the shape of the flower is so handsome.

Coleus are tender tropicals that are generally grown as annuals because they are hardy only in Zone 11. The variously shaped leaves of these popular bedding plants typically combine several colors, such as chartreuse, rust red, cream, and purple-black. Some cultivars sport almost all of these colors combined. The darker the red in the leaf, the more sun the plant will tolerate. Coleus blooms in summer, but the blue to white nettle-like flowers are unremarkable and tend to detract visually from the impact of the foliage. -Debra Lee Baldwin, Regional Picks: Southern California, Fine Gardening issue #127

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.

There are some shrubs that will light up the fall garden with both leaf color and fruit. 'Winterthur' viburnum is one of those shrubs. It begins its display in late summer, as clusters of half-inch-diameter fruit begin to blush pink and become more intense over the course of a few weeks until the whole shrub looks bedecked in bubble gum. The fruit quickly change to a deep blueberry blue as the glossy, leathery leaves become infused with maroon and red. 'Winterthur' maintains a compact, 6-foot-round, multistemmed habit that produces abundant fruit and more intense fall color than the species. In late spring, it's covered with small, off-white, slightly fragrant flowers.

Anyone who gardens in the shade is familiar with heucherella. ‘Sweet Tea’ was bred using Heuchera villosa, a native of the eastern United States, as one of its parents, which has added enough resistance to heat, drought, and humidity to make it able to handle even the extreme climate of Texas. ‘Sweet Tea’ has large, stained, orange-bronze leaves with dark burgundy veins and short spikes of small white flowers that appear in early spring. Its brightly colored foliage, however, is the main reason to have this plant.
