Nodding Onion

Canada Mint is a native perennial plant known for its fragrant edible leaves. It produces small white to purple flowers in clusters around the stem and is commonly found in wet areas, including ditches and along wetlands, lakes, and rivers. The leaves can be eaten fresh or used to make teas and essential oils.

Canada Mint can spread quickly through underground rhizomes, making it well-suited to naturalization and restoration projects where it can spread freely. In smaller urban yards or gardens, container planting is recommended to help manage its growth. If planted directly in the ground, regular care and maintenance may be needed to limit its spread.

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.
