Uvularia grandiflora #1 (Grand Merrybells)

Grand Merrybells, also known as Large-Flowered Bellwort, is an understated native woodland wildflower. The stems seem to poke right up through the leaves (perfoliate) and grow in strong, erect clumps, often around the base of deciduous trees. They prefer rich, moist soils but are somewhat drought-tolerant once established. The large, pendulous, bell-shaped, pale yellow flowers have a sweet fragrance and are in bloom for about two weeks in May. The flowers provide nectar and pollen for insect visitors, and the seeds are dispersed by ants who take them back to their nests to devour the fleshy appendage (elaiosome) and discard them, unharmed, in their midden heaps. This is the perfect place for a seed to germinate, and a common way for spring ephemerals to be spread around to new locations. Grand Merrybells will also spread slowly by rhizomes, eventually forming colonies.

Deer love to eat the delicate foliage of this plant, resulting in its decline in the wild. Extra protection may be necessary in the garden if deer are around.
