Black-eyed susan vine (Thunbergia alata) takes on a new hue with Tangerine Slice A-Peel. The flowers on this variety unfurl in playful shades of orange and red. Black-eyed susan vine is a cinch to grow. It happily clambers up an arch and delivers non-stop blooms all summer long. This vine also adapts well to growing in pots on a tepee trellis. Give this beauty a spot in full sun, except in the Deep South, where afternoon shade is welcome. Butterflies and other pollinator insects visit blooms, adding to the color show. Plants grow 5 to 8 feet tall by 18 to 24 inches wide. Annual vine, hardy in Zones 10-11.
A native plant, trumpet vine (Campsis radicans) is a fast-growing beauty that scales an arch or pergola in a season. It’s famous for trumpet blooms that unfurl in bold orange shades, although you can also find varieties with yellow or red flowers. Blooms are a magnet for hummingbirds and other pollinators. Trumpet vine stems can wander underground, invading planting beds and disrupting patios. It’s best planted not too close to buildings, but makes a perfect choice for training on a yard or garden entry arch or pergola. Prune vines hard in early spring. Plants grow 20 to 30 feet tall and 6 to 8 feet wide. Hardy in Zones 4 to 9. Use caution planting trumpet vine in Zone 6 or warmer, where mild winters allow rampant (some say invasive) growth.
For summer bloom, turn to native, easy-care shrub sweetspire. Scarlet Beauty sweetspire (Itea virginica ‘Morton’) unfurls long white flower clusters mid-June to early July, flooding summer days and nights with luxurious fragrance. Blossoms buzz with pollinator activity, including bees, butterflies and beneficial insects. This is a must-have plant for wildlife gardens. The fall color season unfolds slowly with leaves in shades of vibrant scarlet-reds and deep oranges that hit their peak in early November. Plants thrive in sun to shade, tolerate moist soil and grow 3 to 4 feet tall and wide. Hardy in Zones 4-9. Good to know: If pruning is needed, do so immediately after flowering, before blossom buds form on mature stems. In early spring, remove any stems that fail to leaf out.
A classic native wildflower, purple coneflower (Echinacea purpurea) brings a steady stream of color to gardens all summer long. It’s a hearty plant, withstanding full sun, drought and poor soil of all sorts (clay, rocky, shallow). Plant breeders have worked to improve this flower powerhouse by expanding blossom color and form. The result? You can find (no longer purple) coneflower plants in a rainbow of shades, including red, gold, white, orange and pink. This variety is PowWow Wildberry, which unfurls vivid rose-purple blooms. Coneflowers are deer- and rabbit-resistant. Purple coneflower grows 24 to 60 inches tall and 18 to 24 inches wide. Some newer varieties grow shorter. Hardy in Zones 3-8. Good vase companions for purple coneflower: Oriental or Asiatic lily, Russian sage, catmint, hosta and gas plant.
