Today’s Special is our ‘David’ Summer Phlox. These perennials are growing in 1 inch plug cells for $1.59 each. Grow in moderately fertile, medium moisture, well-drained soil in full sun to light shade. Best in full sun. Prefers rich, moist, organic soils. Needs good air circulation (space well and thin out stems as needed) to help combat potential powdery mildew problems. Intolerant of drought and needs to be watered in dry spells. Avoid overhead watering however. Appreciates a summer mulch which helps keep the root zone cool. Remove faded flower panicles to prolong bloom period and to prevent unwanted self-seeding (cultivars generally do not come true from seed).
‘David’ is a garden phlox cultivar that typically grows in an upright clump to 3-4′ tall. Fragrant, tubular flowers (1/2″ to 1″ diameter) with long corolla tubes and five flat petal-like lobes are pure white. Individual flowers are densely arranged in large, terminal, pyramidal clusters (panicles to 6-12″ long) in summer atop stiff, upright stems which seldom need staking. Long mid to late summer bloom sometimes extends into early fall. Narrow, opposite, pointed, lance-shaped leaves (to 5″ long). Good fresh cut flower. The name Phlox is derived from the Greek word for flame. Zones 3 to 9.
