perennial phlox 'White Admiral'


The 'White Admiral' is a variety of the garden phlox known for its striking, large white flowers. These flowers are densely packed in clusters, known as panicles, that bloom at the top of sturdy stems. The blossoms are noted for their pleasant fragrance and are a favorite among pollinators such as butterflies and hummingbirds. Each individual flower consists of five rounded, flat petals that are fused at the base, forming a tube-like structure. The flowers provide a vivid contrast to the plant's foliage, which consists of lush, green leaves with a lance-shaped appearance. These leaves are arranged opposite each other on the stem, creating a neat and orderly look. The 'White Admiral' stands out in the garden with its showy floral display that lasts through the summer months and into early autumn, providing a long season of interest. It is a popular choice for borders, beds, and cottage gardens, where its white blooms can provide a sense of brightness and purity.

  • water dropWater

    Garden Phlox should be watered deeply once a week, ensuring you provide enough water to soak the root zone. During periods of high heat or drought, watering frequency should increase to twice per week. Use 1 inch of water each time, which is roughly equivalent to 0.625 gallons per square foot. Avoid overhead watering to reduce the risk of fungal diseases; instead, water at the base of the plant early in the day to allow foliage to dry before nightfall.

  • sunLight

    Garden Phlox thrives best in full sun to partial shade. Ideally, provide the plant with at least six hours of direct sunlight each day. If possible, place it in a spot that receives morning sun and afternoon shade to protect it from the intense late-day sun, which can sometimes be too harsh.

  • thermometerTemperature

    Garden Phlox prefers a temperate climate with temperatures between 60 and 90 degrees Fahrenheit. It can survive minimum temperatures down to about -30 degrees Fahrenheit but may not thrive in conditions where the temperature consistently exceeds 90 degrees Fahrenheit. The ideal growing conditions are warm days and cooler nights within the preferred temperature range.

  • scissorsPruning

    Garden Phlox benefits from pruning to encourage bushier growth, to remove spent flower heads, and to prevent disease spread. Prune in early spring to remove any dead or damaged stems and again after the first bloom to promote a second flush of flowers. The best time for pruning is just after the blooms have faded.

  • circleLife cycle

    Phlox paniculata 'White Admiral', commonly known as Garden Phlox, begins its life cycle as a seed, which germinates in late spring when soil temperatures warm. Seedlings establish themselves and grow quickly, developing into a clump of stems with oblong-lanceolate leaves. By mid-summer, the plant enters its flowering stage, producing clusters of fragrant, white flowers that attract pollinators such as butterflies and hummingbirds. After blooming, which typically lasts until early fall, the flowers develop into small seed capsules that release seeds for the next generation. Garden Phlox then enters senescence, with aerial parts dying back as winter approaches. The plant remains dormant during winter, with its root system surviving underground until conditions are favorable to start a new cycle in spring.

    • Propogation time

      Spring to Early Summer

    • Propogation: The most popular method of propagation for Phlox paniculata 'White Admiral', commonly known as garden phlox, is through division. Division is typically done in the early spring or fall when the plant is not in full bloom. To propagate by division, carefully dig up the entire clump of phlox and gently shake off the excess soil. Then, using your hands or a sharp knife, divide the clump into smaller sections, ensuring that each section has a good amount of roots and at least a few shoots. These sections can then be immediately replanted in well-prepared soil, spacing them about 18 to 24 inches (approximately 45 to 60 centimeters) apart to allow room for growth. Water the new plantings thoroughly to help establish the roots. Division not only helps to propagate new plants but also rejuvenates older clumps that might be losing vigor.
