Phantom Hydrangea
Yellow Hedysarum

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.

Yellow Hedysarum is a native perennial wildflower recognized for its clusters of pale yellow to creamy-white, pea-like blooms. Flowering from late spring into summer, it adds subtle colour to grasslands, roadsides, and open woods while attracting a variety of pollinators, especially bumblebees.

As a nitrogen-fixing plant, Yellow Hedysarum enriches soils and supports the growth of surrounding vegetation. Its deep taproot and extensive root system make it drought-tolerant and effective at stabilizing soil. Grizzly bears are known to dig up and eat the nutritious taproot. Its resilience and ecological value make it well-suited for restoration, naturalization, pollinator gardens, and erosion control projects.
