  • circleLife cycle

    The Persicaria amplexicaulis Taurus, commonly known as Red Bistort 'Taurus', begins its life cycle as a seed, which germinates in spring when soil temperatures rise and moisture is abundant. Once germinated, the seedling emerges and establishes a root system, while developing its first leaves to begin photosynthesis. As it matures into a young plant, Persicaria amplexicaulis 'Taurus' develops a clumping habit with robust stems and large leaves, growing actively during the spring and summer months. Flowering typically occurs in mid to late summer, presenting elongated spikes of densely packed, deep red flowers that attract pollinators such as bees and butterflies, facilitating cross-pollination. Following pollination, seeds are produced which can be dispersed by wind, water, or animals, completing the reproductive stage. As a hardy perennial, Persicaria amplexicaulis 'Taurus' will die back to the ground at the onset of winter, with its root system remaining dormant until the next spring, when the cycle begins anew.

      Spring-Early Summer

    • The Persicaria amplexicaulis 'Taurus', commonly known as Red Bistort or Fleece Flower, can be propagated most effectively by division. This method is typically carried out in the spring, just as the plant begins to show new growth. To propagate by division, carefully lift the clump from the ground and use a sharp spade or knife to cut it into smaller sections, ensuring that each section has a piece of the root system and several shoots. Replant the divisions immediately at the same depth they were originally growing, spacing them about 12 to 15 inches (approximately 30 to 38 centimeters) apart to allow ample room for growth. Water the new plants thoroughly to settle the soil around the roots and to help establish them in their new location. This method of propagation is quick and effective, often resulting in new plants that will bloom within the same season.
