Bistort: A Versatile Plant with Medicinal and Ornamental Uses
Introduction
Bistort is a fascinating plant with a variety of common names, including serpent grass, meadow bistort, and viviparous knotweed. It’s a member of the buckwheat family and is commonly found in mountainous meadows, moist grasslands, and swampy areas throughout much of western North America and Canada.
Physical Characteristics
Bistort plants have long, sparsely leafed stems that grow from short, thick, S-shaped rhizomes. These rhizomes give rise to the plant’s various Latin names, which sometimes place it in the genus Polygonum or Persicaria. The stems bear spikes of tiny, pink/purple or white flowers in midsummer, depending on the species.
Reproduction
Bistort flowers rarely produce seeds. Instead, the plant reproduces by tiny bulbs that develop in the axils of the leaves. These bulbs can be planted directly in the garden to propagate new bistort plants.
Growing Conditions
Bistort is suitable for growing in USDA plant hardiness zones 4 through 9. It can tolerate partial shade or full sunlight, but prefers shade in hot climates. The soil should be moist, rich, and well-drained. Adding plenty of compost to the soil before planting is beneficial.
Planting and Propagation
Bistort can be propagated by planting seeds or bulbils directly in the garden after all danger of frost has passed in late winter or early spring. Alternatively, you can start seeds indoors a few weeks ahead of time. Mature plants can also be divided in early spring or autumn to create new plants.
Care and Maintenance
Bistort plant care is relatively simple. Water generously and don’t allow the soil to dry out. Remove wilted flowers regularly to promote blooming throughout the season. Pick bistort flowers for bouquets as often as desired.
Uses
Bistort has a variety of uses, both ornamental and practical. It’s often used as a groundcover in boggy areas, along ponds, or in shady, moist areas. When planted en masse, it creates a stunning display.
Medicinal Uses
Native Americans have traditionally used bistort shoots, leaves, and roots as vegetables, often adding them to soups and stews or with meat. When ground into a poultice, bistort leaves can help staunch bleeding and soothe boils and other skin irritations.
Culinary Uses
In Europe, tender bistort leaves are incorporated into a pudding traditionally eaten at Easter. Also known as passion pudding or herb pudding, this dish is often cooked with butter, eggs, barley, oats, or onions.
