Large bellwort


Uvularia grandiflora is a perennial herb growing from a rhizome and thickened fibrous roots, with simple to occasionally branched stems, 35-70 cm tall. The simple, alternate, ovate oblong to elliptic leaves are 6-12 cm long and 2-6 cm wide, smooth on top and hairy below. The leaf margins are entire and membranous. The solitary flowers are terminal and drooping. There are 6 yellow tepals that appear twisted, 2.5-4.5 cm long, the tips pointed, with 2mm diameter nectaries toward the base. The 6 stamens are shorter than the petals. The fruit is a 3-lobed capsule containing several rounded seeds. Large bellwort blooms in April and May in moist woodlands along the eastern edge of South Dakota.

Additional Notes

Large bellwort is an excellent shade plant for a native woodland garden. They are early blooming and add color underneath a wooded plot. Bellwort spreads slowly by rhizomes and will create mass plantings in a relatively short amount of time. Bumblebees and other native bee species are attracted to the nectar and collect pollen from the flowers.
