When I first saw the crimson flowers of Rüütel™ (‘Kiviruut’) in 2009, I was like a wide-eyed kid experiencing a Christmas miracle. It’s truly a luscious color. The 7-inch-wide flowers feature deeply grooved tepals with ruffled edges and similarly colored stamens, which give it a monochromatic look that I love. Rüütel™ blooms from late spring to midsummer on stems that only reach 6 feet tall, making it perfect for small patios where the luxuriant blossoms can be viewed up close. -Richard Hawke, Big blooming clematis, Fine Gardening issue #146

(Clematis Picardy™)

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

A clematis doesn’t have to be big to be bold. Picardy™ (‘Evipo024’) epitomizes this rule; its compact habit certainly doesn’t restrain the boldness of the vivid, violet-red flowers. This is no shrinking violet! Picardy™ is free flowering and often reblooms into late summer. Topping out at 5 feet tall, its petite size is suitable for containers and for small patios where larger clematis would be overwhelming. -Richard Hawke, Big blooming clematis, Fine Gardening issue #146, page 47

This tireless bloomer is best known for its small, tubular flowers, each colored in vivid orange hues and tipped with white, like the ash on a glowing cigar. Each plant creates a mass of slender branches with lance-shaped, mid-green leaves. At the tip of the branches are fireworks bursts of unusual cigarlike flowers, each 1-1/4 inches long and softly hairy. Though the flowers look orangey, they are actually colored red and shaded with green-yellow.

Of the maybe 10,000 named dahlias introduced in the 1800s—when dahlias ranked right up there with roses in popularity—only three survive. One of them is 'Kaiser Wilhelm', introduced in 1892. Its 3-inch flowers have neatly curled petals of soft custard-yellow brushed with burgundy, and a green button eye just like that of an old rose. The plant can grow to 5 feet.

Dahlia 'Zorro' Dahlia 'Zorro'
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

For a change of pace, 'Zorro' looks fantastic floating stemless in a bowl of water. The ruffled petals accentuate the dark red hue. Staking is a must to prevent the stems from flopping beneath the weight of its huge and heavy blooms. Pinch back the young shoots to promote branching and sturdier stalks. 'Zorro' consistently produces quality tubers for division and, as such, is the perfect cultivar to start (or sustain) a dahlia collection. -Alastair Gunn, Dahlias that deliver, Fine Gardening issue #121

A captivating little plant for the front of the border, tassel flower produces small, scarlet-orange pompons which, when viewed from a distance, seem like they’re floating in air. The flowers cluster at the top of wiry stems that rise from a basal rosette of blue-green leaves. Plants occasionally self-sow when sited in a good location. With its small habit, tassel flower lends itself well to container gardens and fresh-cut flower arrangements, adding an element of whimsy. Its delicate and airy nature looks best with bold-leaved or showy plants in the background, creating a see-through effect. To magnify their magic, mass several plants together.

Red spider lily’s brilliant red flowers remind me of an azalea’s ball truss. Blooms fade quickly in hot weather, but a higher degree of shade helps them last a while longer. Depending on where it grows in the Southeast, red spider lily blooms from early September to mid-October. After the bloom stalks fade away, foot-long, strap-shaped leaves emerge and last through winter. Red spider lily is an heirloom bulb that is easily passed from hand to hand.

Mina lobata Mina lobata

(2 user reviews)

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.

'Maraschino' bush sage is a superb Salvia that is irresistible to hummingbirds and gardeners alike. Even after dying back to the ground in winter in the cooler zones, this plant comes back in full force each spring, reaching its full height and covering itself with cherry red blooms by midsummer. The flowers bloom nonstop through the first hard frost, and the leaves are sweetly fragrant. Plants do best when given afternoon shade. 'Maraschino' grows to 3 feet tall.

This upright tender perennial provides rich color for annual bedding schemes where it is not hardy. Its deep red flowers are borne on 2- to 2.5- foot, open spikes from summer to autumn. Plants grow to about a foot wide and bear hairy, oval to heart-shaped leaves. Salvias are some of the showiest plants for containers, annual borders, and mixed borders. Butterflies and hummingbirds love them.

This native of the American Southwest and Mexico forms an evergreen shrub or shrubby perennial with dark, glossy leaves that are small (but slightly larger than most microphyllas) and softly toothed. It blooms off and on all summer, and again, more vigorously, in late summer and autumn, in blossoms of cherry-red. Its attractive foliage cloaks the plant to the ground, so it is well suited to the front of the border. It can grow to 4 feet tall and twice as wide.

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.

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
