‘David’ is a garden phlox cultivar that grows in an upright clump, reaching 3-4 feet tall. It produces fragrant white 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.
They prefer rich, moist, organic soils and are best suited to climates with mild summers rather than hot and humid conditions. Thrive in full sun up north, but requires some protection from the full Texas sun. Good air circulation is essential to prevent potential powdery mildew problems, so it’s necessary to space the plants well and thin out stems as needed. 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, and pruned plant material removed from the garden to minimize the risk of powdery mildew infection in the following growing season. Removing faded flower panicles will help prolong the bloom period and prevent unwanted self-seeding (cultivars generally do not produce true offspring from seed).
