Nodding Onion
White Fringe Tree

Nodding Onion is a native perennial wildflower known for its nodding clusters of flowers that range in color from white to pink to purple. The lightly scented blooms provide pollen and nectar for pollinators, especially bees, which can collect while hanging upside down, a capability most other insects lack.

The narrow, grass-like leaves of the Nodding Onion can be used as a seasoning in cooked dishes, though bulbs and raw leaves should not be eaten in large quantities. All parts of the plant have an onion-like aroma when bruised, which helps deter deer and rabbits. They can self-seed readily, so removing spent blooms helps manage their spread. Tolerant of a range of soils, including alkaline, it is well-suited for a variety of plantings, including pollinator gardens and naturalization projects.

White Fringe Tree is known for its fringe-like white flowers. It can either grow as a small tree or a large multistemmed shrub. The White Fringe Tree has separate male and female plants. Both male and female flowers have white fringe-like petals, but the male flowers are longer and showier. The female flowers give way to clusters of dark blue to black berries. These berries are not edible for humans but attract birds and other wildlife.

The White Fringe Tree is tolerant of clay soils, saline soils, and air pollution but does not do well in prolonged dry conditions.
