perennial phlox 'David'


The garden phlox variety known as 'David' is renowned for its showy clusters of brilliant white flowers that grace the top of the stems.

Each floret has a small, tubular base that flares out into five flat, petal-like lobes. The plant has a bushy, upright growth habit with sturdy stems that are sometimes tinged with green to purplish hues, supporting the weight of the flower heads. The foliage is equally attractive; the leaves are pointed, with a slightly textured surface and smooth edges, which complement the blooms and maintain ornamental value even when the plant is not in flower. The overall appearance of Phlox paniculata 'David' is of a lush, vibrant plant that brings a bright and refreshing look to any garden setting with its crisp white flowers and rich greenery.

  • circleLife cycle

    Garden Phlox 'David' starts its cycle as seeds, which upon germination in early spring, develop into small seedlings. As temperatures warm, these seedlings grow into sturdy stems with lance-shaped leaves. Throughout the summer, the plant reaches maturity and produces large clusters of fragrant white flowers that attract pollinators. After flowering, the plant sets seed, dispersing them to produce new plants in subsequent seasons. As fall arrives, the plant begins to die back and enters a period of dormancy through the winter months. In the following spring, Garden Phlox 'David' can re-emerge from its root system or from the new seeds that were spread, continuing its life cycle.

      Spring-Early Summer

    • Garden Phlox, known as Phlox paniculata 'David', is a popular perennial that can be propagated in several ways, but division is the most commonly used method. The ideal time to propagate Garden Phlox by division is in early spring or late summer to early fall, when the plant is not in active bloom. To propagate through division, you start by digging up an established clump and gently separating it into smaller sections, making sure each section has several shoots and a healthy root system. These sections can then be replanted at the same soil depth as the original plant and spaced about 18 to 24 inches apart (approximately 45 to 60 centimeters) to allow for growth. Water the new divisions thoroughly after planting to help establish them. With proper care, these divisions will grow into strong, flowering plants in the following season.
