red bistort 'Golden Arrow'


The Persicaria amplexicaulis 'Golden Arrow', commonly referred to as the mountain fleece, features a striking contrast of foliage and flowers that creates a visual appeal in gardens. The most noticeable characteristic of this variety is its vibrant, golden-yellow leaves that offer a luminous backdrop for the blossoms and add a bright splash of color to the landscape throughout the growing season. Adorning the top of the plant are slender, spike-like flower clusters that range in shades from a deep, rich red to a softer pink hue. These tiny, densely packed flowers form elongated inflorescences that elegantly arch or nod, adding a soft, feathery texture to the plant's profile. The blossoms are beloved by pollinators and can add a lively buzz to the garden as bees and butterflies are attracted to the nectar-rich blooms. The stems of the mountain fleece are sturdy and upright, often tinged with the same reddish color as the flowers, providing a cohesive look to the plant. The leaves are lance-shaped, and their golden color is especially striking when backlit by the sun, transforming the plant into a glowing focal point within a garden bed or border. Throughout the seasons, the plant maintains its visual interest, with the foliage taking on warmer, sometimes orange or coppery tones as the cooler weather of fall approaches. The overall effect of the Persicaria amplexicaulis 'Golden Arrow' is one of vibrant, enduring color and texture that can complement a variety of garden styles and plant combinations.

  • circleLife cycle

    Persicaria amplexicaulis 'Golden Arrow', commonly known as Bistort or Mountain Fleece, begins its life cycle as a seed which germinates in spring when the soil warms up. The seedling establishes a root system and shoots emerge, the plant then develops into a clump-forming perennial with characteristic golden-green leaves. During the summer, tall flower spikes with tiny, densely-clustered reddish-pink flowers appear and attract pollinators. After pollination, seeds develop, which then disperse to start the next generation of plants. In autumn, the plant's above-ground foliage dies back with the onset of colder temperatures. Finally, it overwinters as a root system, remaining dormant until the return of favorable conditions in the next spring.

    • The most popular method of propagating Persicaria amplexicaulis 'Golden Arrow', also known as Mountain Fleece, is by division. This is typically done in the spring as new growth appears. To propagate by division, carefully dig up the entire plant and gently separate the root ball into smaller sections, each with a portion of the root system and several shoots. It's important to ensure that each new section has enough roots to sustain the plant. Replant the divisions at the same depth they were growing at originally and water well to establish. This straightforward technique helps to rejuvenate older clumps and also to create new plants for the garden or to share.
