Phlox paniculata 'Robert Poore'

Phlox paniculata, also known as garden phlox, is native to New York to Iowa and south to Georgia, Mississippi, and Arkansas. It has spread from gardens and grown naturally in areas beyond its original native range. 

'Robert Poore' is a garden phlox cultivar that grows in an upright clump, reaching 4-5 feet tall. It produces fragrant, deep purple-pink tubular flowers with long corolla tubes and five flat petal-like lobes. The flowers form large, terminal, pyramidal clusters in summer on stiff, upright stems that rarely require staking. The bloom usually extends from mid to late summer, sometimes into early fall. The plant has narrow, oppositely arranged, pointed, lance-shaped leaves and is suitable for use as cut flowers.

These plants thrive in moderately fertile, medium moisture, and well-drained soil in full sun to light shade. They prefer rich, moist, organic soils and are best suited to climates with mild summers rather than hot and humid conditions. This cultivar is one of the most mildew resistant. They are intolerant of drought and should be watered during dry spells, but overhead watering should be avoided. The plants benefit from summer mulch to keep the root zone cool. In winter, the plants should be pruned to the ground.
