Nodding Onion
White Meadowsweet

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 Meadowsweet is a woody, deciduous shrub that begins to bloom in early summer with small white and pink flowers. Its foliage turns from a light green into an attractive golden-yellow later in the fall.

The White Meadowsweet, also known as Mead-Wort or Bride-Wort, is favored by birds and butterflies but is largely ignored by deer. They produce small brown berries in the summer, and while they are technically edible, they are not sweet and are more desired by wildlife.
