Katherine Rowe explores a new one to love among old garden favorites, ‘Jeana’ garden phlox.
Garden phlox brightens the border with a profusion of domed clusters with starry blooms. In cultivation since the 1600s, the historic perennials are a beloved staple and form a showy backdrop among other summertime blooms and grasses. Most species are North American natives, particularly to the eastern United States, including Phlox paniculata. Phlox, from the Greek for “flame,” boasts an eye-catching floral display.
‘Jeana’ tall garden phlox is an award-winning cultivar that boasts months of blooming and superior cold hardiness. Trusses of lightly fragrant lavender-pink blooms are a magnet for butterflies and moths (their obligate pollinators), as well as hummingbirds. ‘Jeana’ brims with ecological and ornamental value; it’s just the multifaceted, hardworking, lovely perennial we need in our collections.
What is ‘Jeana’ Garden Phlox?
Phlox paniculata is the most popular of all the Phlox species. Tall garden phlox, or flowering phlox, has bundles of showy flowers atop upright stems. From pale pink to crimson, color-rich selections abound. Whether old-fashioned pass-along plants or newer cultivars, P. paniculata earns its spot in the border.
The exceptionally sturdy and floriferous ‘Jeana’ selection is the 2024 Perennial Plant of the Year. The Perennial Plant Association awards those that grow across various climates, need little additional maintenance, and have good pest and disease resistance and landscape value.
Taking top place in Mt. Cuba Center’s three-year phlox trials, ‘Jeana’ shows exceptional powdery mildew resistance, a long flowering time with a spectacular display, and a big pollinator draw. Of all the varieties in the trial, ‘Jeana’ attracted the most butterflies, and Eastern Tiger Swallowtail, in particular. They also attract hummingbirds with their tubular, nectar-rich blooms.
‘Jeana’ has a tall, sturdy habit that supports the big show of deep lavender-pink florets. Domed clusters top stiff stems that reach five feet tall. While each floret is smaller than other varieties, the number per bunch and extended flowering more than make up for their size.
In addition to its ornament, ‘Jeana’ offers ecological value. The nectar-rich blossoms are a favorite among butterflies and other pollinators. As a native cultivar from a wildly growing selection, it’s a strong performer in optimal growing conditions.
‘Jeana’ is the backbone of borders, cottage gardens, pollinator themes, and naturalistic arrangements. Pair it with other natives and their cultivars like amsonia, monarda, switchgrass, Joe Pye weed, salvia, and hardy geranium. These are a match for pollinator support and a long season of visual interest.
Characteristics
The clump-forming perennial spreads up to four feet and has tall, five-foot stems. Showy trusses of pips (individual flowers) are smaller than other varieties at half an inch, but the six-inch flowerheads last into early fall. The floral show hits peak bloom in mid to late July and extends into October.
‘Jeana’ produces few seeds and won’t reseed in the landscape like older garden phlox varieties. The lack of seed production means a long-lasting floral display, with less energy directed to seed production and more into continual flowering.
With excellent disease resistance to powdery mildew, ‘Jeana’s’ bright green, elliptical, and pointed leaves remain attractive all season.
Native Area
Phlox paniculata is native to the United States from the Midwest to the mid-Atlantic and southward. It grows naturally along stream banks, riparian areas, and in moist low woodlands and meadows.
‘Jeana’ is a selection of a native wild phlox. Gardener Jeana Prewitt discovered it growing wildly in a large colony along the Harpeth River near Nashville, Tennessee. While others in the group showed powdery mildew, this strong selection was mildew-free.
Planting
Fall and spring are the best times to plant the perennials. If there is adequate moisture for strong root systems to develop, plant them at any time in areas with mild summers. Avoid planting phlox in stressful conditions, such as high heat, drought, or freezing soil. The cool, moist conditions of spring and fall present the least stress on new plantings. They’ll be able to develop roots before hot summers or cold winters, respectively.
Good air circulation is essential for garden phlox and sets the foundation for health. Allow proper spacing at two to three feet apart to plan for the mature spread.
At planting, dig a hole two to three times as deep and wide as the size of the root ball. Loosen any tightly wound, pot-bound roots so they can grow outward. Position crowns an inch-and-a-half below the soil surface. Water deeply after planting to settle the roots and soil.
