Backyard Aromatherapy!
Magenta-pink fragrant flower panicles of Phlox Ultraviolet cover its bushy bright green foliage. Foliage parades charcoal-black stems when it first emerges. From the Luminary Series, these Garden Phlox were developed for incredible performance, enticing colors, and improved mildew resistance over typical Phlox paniculata varieties. Stunning flowers will exhibit more purple tones when the sun is not present. Full sun is also beneficial for mildew prevention. Butterflies and hummingbirds will be frequent visitors to Phlox Ultraviolet. When most plants are on their summer siesta, Garden Phlox provides a much needed shot of color.

Phlox General Information

Phlox paniculata provide unsurpassed flowering in summer, clear crisp colors and fragrant flowers in profusion. Good cut flower, a choice selection for the colder zones. We specifically carry disease-resistant Phlox varieties. Idaho has restricted all potted plant material from being shipped into Idaho at this time.

Phlox Plant Care

Prefers moist, humus-rich soil. Phlox can be divided every 3-5 years in spring or fall. In spring, just as new growth appears, dig up the plant and divide clump with a sharp knife or spade into at least 2 or 3 shoots and a portion of the root system. Plants divided in fall should be mulched with a 4-6” layer of straw or pine needles to prevent heaving. Remove mulch in early spring. Cut back by 1/2 in late spring/early summer to encourage more compact plants. Shear off spent blooms just above foliage. To help avoid the possibility of mildew; provide plants with good air circulation (in spring, snip out all but 4-6 stems in a mature clump), avoid drought-like conditions, site plants where they will get sufficient light of six hours or more each day. Should a spray program become necessary, products exist on the market for prevention and control. Removing mature blooms will prevent seeding, if not desired. Clean up spent foliage in spring.

Plantable Pots

Our plants are grown in 3.5x3.5x4” plantable pots. Made from 100% biodegradable coconut husk fibers (coir), these pots have tremendous advantages over plastic pots. With better air exchange, this "breathable" pot fosters robust root growth and reduces transplant shock since you can plant the pots directly in the ground. The pot naturally becomes part of the soil on its own over time—no composting required—and since they're made from a renewable resource that requires very little energy, they're earth-friendly too!

We offer a 100% guarantee for all our perennials to reach you in good condition and to grow. If you're not satisfied, we'll reship or refund immediately. Please don't hesitate to contact us if you have questions or concerns—we share your passion for gardening and want your new plants to thrive in your border!
