Phantom Hydrangea
Showy Milkweed

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.

Showy Milkweed is a native perennial wildflower known for its fragrant clusters of pink to purple, star-shaped flowers. It is an essential plant for Monarch butterflies, acting as a critical host plant for caterpillars and a nectar source for adults. Blooming from early to mid-summer, these flowers also supply nectar to many other pollinators, including bees, butterflies, moths, and hummingbirds.

Ideal for butterfly conservation, pollinator gardens, and naturalization projects, Showy Milkweed thrives in a wide range of soils, including dry and rocky ground. While it spreads via underground rhizomes to form colonies, it is much less aggressive than Common Milkweed (Asclepias syriaca).

Note: All parts of the plant contain toxic cardiac glycosides, especially the milky sap. Do not ingest any part of the plant and prevent sap from contacting skin or eyes. Toxic to humans, pets, and livestock.
