  • circleLife cycle

    Persicaria amplexicaulis 'Alba', commonly known as White Bistort or White Fleece Flower, begins its life cycle as a seed, which, when sown in fertile, moist soil, will germinate usually in the spring. The seedling emerges and develops into a young plant with characteristically broad leaves, gradually maturing over the course of several weeks. As the plant reaches maturity, usually in its second or third year, it produces tall, slender spikes with small white flowers blooming from early summer to mid-autumn. After pollination, often by insects, the flowers give way to small fruits (achenes) that contain the seeds for the next generation. In winter, White Bistort dies back to the ground, surviving as a perennial root system that resprouts in the following spring to complete the cycle. Over years, it can form large clumps through vegetative reproduction, expanding its presence in a garden or naturalized area.

      Summer to Fall

    • The most popular method for propagating Persicaria amplexicaulis 'Alba', commonly known as White Bistort or Mountain Fleece, is by division. This process is generally done in the spring as the plants begin to grow or in the early fall, after the blooming period has concluded. To propagate by division, gently dig up the plant and carefully separate the root clump into smaller sections using a sharp knife or spade, ensuring that each division has a section of the root system and several shoots. These divisions can then be immediately replanted in the ground at the same depth they were originally growing, spaced about 12 to 24 inches apart (approximately 30 to 60 cm). The soil around the new divisions should be firmed down and watered thoroughly to help establish them. This method is simple and effective, promoting healthy growth and increasing the number of White Bistort plants in your garden.
