Large-flowered bellwort (Uvularia grandiflora) is a rhizomatous woodland perennial native to eastern and central North America. In mid-spring, arching stems carry drooping, twisted yellow bells and appear to pass through the leaves - a structural trait called perfoliate growth. It is one of the most reliable native perennials for colonizing shaded ground beneath deciduous trees.
Plants spread at a measured pace by rhizome, building loose colonies over several years. Foliage persists through early summer then goes fully dormant by midsummer, so pairing it with later-emerging species fills the gap. Loose leaf-mold mulch mimics natural woodland duff and maintains the consistent soil moisture this species requires. Slightly acidic, humus-rich soil produces the most vigorous growth.
Cherokee and other Native peoples used the roots for joint pain and back complaints. Young spring shoots were gathered before leaves fully unfurl and eaten much like asparagus.

Fungal leaf spot
Brown or purplish spots on the leaves, often ringed with a yellow halo, that spread and merge in warm, humid, or wet weather; heavily spotted leaves yellow and drop early.
Pick off spotted leaves and clear fallen debris to remove overwintering spores. Improve air circulation by thinning, and water at the base so foliage dries quickly. If it persists, apply a copper- or sulfur-based fungicide at the first sign.
Botrytis (grey mould)
Grey fuzzy mould on petals and stems, worst in cool wet conditions.
Remove affected parts immediately. Improve air circulation. Avoid overhead watering. Apply copper fungicide if severe.
Root rot
Plants wilt, yellow, and stunt even in moist soil; lower stems and roots turn brown, soft, and mushy and the plant may collapse. Most common in heavy, wet, or poorly drained ground.
Improve drainage and stop overwatering, and never plant too deep. Lift and destroy badly affected plants along with the soil around the roots. Grow in raised or free-draining beds to prevent it returning.
