  • circleLife cycle

    Phlox paniculata 'Logan Black', commonly known as Tall Garden Phlox, begins its life cycle as a seed that germinates in spring when soil temperatures rise. The seedling grows into a clump-forming perennial with strong stems and dark green foliage, typically reaching full size within a few months. During summer, the plant produces clusters of scented, deep purple or black flowers that attract pollinators such as bees and butterflies. Following pollination, the flowers develop into small seed pods that ripen by fall, releasing seeds for the next generation. Throughout the winter, the plant enters a dormant phase, dying back to the ground after frost hits, but its root system remains alive underground. In the spring, new shoots emerge from the surviving roots, repeating the yearly growth cycle.

    • Propogation time


    • Propogation: The most popular method for propagating Garden Phlox, specifically the 'Logan Black' variety, is by division, which is typically done in early spring or early fall when the plant is not in active bloom. To propagate by division, you first dig up an established clump of phlox and gently separate it into smaller sections, making sure that each section has a good amount of roots and at least a few shoots. After the division, the sections should be replanted at the same depth they were growing before and spaced approximately 18 to 24 inches (about 45 to 60 centimeters) apart to give each new plant sufficient room to grow. The soil should be kept evenly moist until the new divisions are well established. This method of propagation helps rejuvenate older plants, encourages vigorous growth, and is an effective way to increase the number of plants in your garden.
