Uvularia grandiflora aka Bellwort

Uvularia grandiflora is a perennial known as large-flowered bellwort. It belongs to the Colchicaceae family and grows from rhizomes. Its native range spans central and eastern North America. This includes parts of Canada and much of the eastern United States. Wild plants grow in rich woods, wooded slopes, and river valleys. These sites often have moist soil with plenty of humus.

Garden plants form upright clumps with a soft, drooping look. They reach about 1.5–2 feet [0.46–0.61 metres] tall. Clumps spread about 1–1.5 feet [0.30–0.46 metres] wide. RHS describes taller plants reaching 2.5 feet [0.75 metres]. Its broad height band extends to 3.3 feet [1 metre]. Mature stems split into two or three branches. The round stems have a powdery coating. Green leaves grow in an alternate pattern along them. Each leaf base wraps around the stem. Fine hairs cover the pale lower surface. The lance-shaped leaves can reach half a foot [0.15 metres] long. Plants lose their leaves at the end of the growing season.

Yellow flowers hang from the stems in April and May. Local flowering dates may vary across the plant's range. Each narrow bell has six smooth, twisted tepals. These are flower parts that resemble both petals and sepals. The flowers have a light scent and attract pollinators. A plant's bloom period lasts about two weeks. Seed capsules follow the flowers and appear in July and August. Each capsule has three rounded lobes and three seed chambers. Those chambers hold several seeds.

Bellwort grows in partial or deep shade. It prefers rich, moist soil that drains well. Loam and clay suit it, across acid to alkaline conditions. It can also cope with brief dry spells. Sources rate it for USDA zones 4–9 and RHS H7. Growth proceeds at a moderate pace, with little upkeep needed. No pruning is required. Plant it in woodland beds, shaded borders, or naturalized areas. Groups fit beneath shade trees and along woodland edges. The flowers also suit cutting. Rhizomes produce offsets, which can form small colonies. Divide clumps or sow fresh seed to raise more plants.

Serious insect and disease problems are uncommon. Slugs can harm young shoots, and snails may also attack. Deer often damage the plants. Plants For A Future lists no known edible uses or hazards.
