  • water dropWater

    The Red Bistort should be watered thoroughly, allowing the top layer of soil to dry out slightly between waterings. This plant prefers consistent moisture, so during the growing season, water it approximately once or twice a week, supplying about 1 gallon per plant each time, depending on the weather conditions. During hot, dry spells, more frequent watering may be necessary. In the cooler months, when the plant is not actively growing, reduce watering frequency. It's important not to overwater, as this can lead to root rot, so always check soil moisture before adding more water.

  • sunLight

    Red Bistort thrives in full sun to partial shade. The best spot for this plant is where it can receive at least 4 to 6 hours of sunlight daily. However, in areas with intense afternoon sun, providing some afternoon shade will help protect the plant from scorching. The ideal location would accommodate morning sunlight and dappled afternoon shade to ensure vibrant growth without overheating.

  • thermometerTemperature

    Red Bistort grows well in a range of temperature conditions, but ideally, it prefers average garden temperatures between 60°F and 75°F. The plant is hardy and can tolerate temperatures down to about 0°F, making it suitable for growing in regions with cold winters. However, it's best to protect the plant from extreme temperature fluctuations and bitterly cold temperatures below 0°F that could potentially damage or kill it.

  • scissorsPruning

    Pruning the Red Bistort is beneficial for maintaining its shape and encouraging fresh growth. It's best to prune in early spring to remove any dead or damaged stems from the previous year. Additionally, deadheading the spent flower spikes after blooming can encourage a second flush of flowers. Pruning can be done yearly, or as needed, to keep the plant looking tidy.

  • bambooSoil

    Mountain Fleece prefers fertile, moist but well-drained soil with a pH range of 6.0 to 7.0. To achieve optimal growth, a mixture of garden soil, peat, and compost or well-rotted manure will provide the necessary nutrients and structure. Regular mulching can help to retain moisture and provide additional organic matter.

  • plantRepotting

    Mountain Fleece doesn't require frequent repotting and can thrive in the same location for several years. Division or repotting is generally only necessary if the plant outgrows its space or if clumps become too dense, typically every 3-4 years.

  • circleLife cycle

    The life of Persicaria amplexicaulis 'Rosea', commonly known as Mountain Fleece 'Rosea', begins with seed germination in spring, typically in a moist and warm soil environment. Once the seeds have germinated, the young seedlings will emerge and begin the vegetative growth phase, developing a robust root system and foliage. As the plant matures, it enters the flowering stage in summer to early autumn, with the distinctive rose-pink spikes attracting pollinators such as bees and butterflies. After pollination, seeds develop and are dispersed later in autumn, either by wind or with the assistance of animals. During the winter, the plant enters a period of dormancy, with the above-ground parts dying back and the roots surviving in the soil. With the return of favorable conditions in the next spring, the cycle restarts from the existing rootstock, or new plants arise from self-sown seeds.

    • Propogation time

      Late spring to early summer

    • Persicaria amplexicaulis 'Rosea', commonly known as Red Bistort or Mountain Fleece, is best propagated by division. The best time to propagate this perennial is in the spring, just as the new growth is emerging, or in the fall, when the plant has finished flowering and is going dormant. To propagate by division, carefully lift a mature clump from the ground using a spade, ensuring to get as much of the root system as possible. With a sharp knife or garden spade, segment the clump into smaller divisions, each with a portion of the root system and several shoots. Replant these divisions at the same soil depth they were previously growing, spacing them 12 to 18 inches (30 to 45 centimeters) apart to allow adequate room for growth, and water them well to help establish the new plants. This method often results in a high success rate and allows gardeners to expand their collection or share plants with others.
