A Phlox for the Phront! Unusual for a Garden Phlox, this petite charmer can be placed front and center to flaunt its bright pink overlapping petals and glowing eyes. Beloved for their fragrant, large flower trusses and mid-summer color.

From the Top Shelf® Series, Phlox Cosmopolitan will fill the air with sweet perfume. Dwarf, compact and well-branched. Phlox, derived from the Greek word meaning flame is in reference to its intense flower colors. When most plants are on their summer siesta, Garden Phlox provide 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!
