bistort 'October Pink'


The Persicaria amplexicaulis 'October Pink', commonly referred to as the 'Mountain Fleece', showcases distinct features that adorn gardens with its aesthetic appeal. The most striking aspect of this plant is its profusion of elongated, slender spikes that boast delicate tiny pink flowers. These flower spikes bloom profusely, creating a haze of soft pink that adds a touch of romance to the garden landscape. The blooms have a fluffy appearance, drawing pollinators and admirers alike. The foliage of the Mountain Fleece is equally attractive, comprising large, broad leaves that cling close to the stems. Their lush green color provides a perfect backdrop for the vibrant pink flowers and adds a robust and full-bodied presence in the garden. Typically, the leaves have a slightly glossy finish and a pointed, heart-shaped base that clasps the stem, fitting the 'amplexicaulis' part of its name, which means 'clasping the stem.' The overall shape of the plant is bushy, forming clumps that spread outwards with abundant growth. This habit makes it an excellent choice for filling in gaps in borders or adding structure to planting schemes. Its enduring display from mid-summer to fall grants it a prolonged period of visual interest in the outdoor space. Mountain Fleece is also noted for its undemanding nature and its ability to thrive in a range of different soil types, providing they are moist. Its resilience and the easy-going nature make it a favored choice for gardeners seeking both beauty and reliability.

  • circleLife cycle

    Persicaria amplexicaulis 'October Pink', also known as Mountain Fleece 'October Pink', begins its growth cycle in early spring as temperatures rise and the ground thaws. New shoots emerge from the plant's rhizomatous root system, developing into lush, bushy foliage. During late spring to early summer, leafy flowering stems elongate, and by mid to late summer, slender, spike-like pink flowers start to appear. These flowers, attractive to pollinators such as bees and butterflies, continue blooming into the fall, usually peaking in October, hence the cultivar name 'October Pink'. Once the flowering season concludes and temperatures drop, the plant's aerial parts die back to the ground, entering a period of winter dormancy. In this dormant stage, the plant conserves energy within its roots, surviving until the cycle recommences with the following spring's warmth.

      Summer to Fall

    • Persicaria amplexicaulis 'October Pink', commonly known as Red Bistort or Mountain Fleece, is best propagated through division. The ideal time for propagating this hardy perennial is in the spring, after the threat of frost has passed. To propagate by division, first, dig up the plant carefully to minimize root damage. Then, using a sharp spade or knife, divide the root clump into smaller sections, each with a portion of the root system and several shoots. Replant the divisions at the same depth they were originally growing, spacing them about 15 to 18 inches (approximately 38 to 46 cm) apart to allow for growth. Water the new plantings thoroughly to help them establish. This method is straightforward and usually results in a good success rate, with the divisions quickly growing into robust plants.
