Phantom Hydrangea
Nodding Onion

Phantom Hydrangea is a striking deciduous shrub with impressive blooms. It is multi-stemmed and produces pale green flowers that fade to white and soft pink as they mature. These flower clusters can reach up to 15” (40cm) long and while other shrubs will droop from the flowers' weight, Phantom Hydrangea has sturdy stems that support them.

This adaptable shrub will make a beautiful addition to your yard as a flowering hedge or as an ornamental plant on its own. Try pruning the flowers after they are spent to get even larger flower heads.

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.
