Phantom Hydrangea
Black-Eyed Susan

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.

Black-Eyed Susan is a striking native wildflower known for its bright yellow, daisy-like flowers with dark center disks. With deadheading, the plant can bloom for an extended period, from mid-summer to early fall. These cheerful flowers attract a variety of pollinators, including bees and butterflies. Adding to its ecological value, the plant also acts as a host for the Wavy-Lined Emerald Moth (Synchlora aerata) and the Silvery Checkerspot (Chlosyne nycteis) butterfly.

While it is typically a short-lived perennial or biennial, the plant freely self-seeds. This allows it to persist in the landscape, particularly in natural areas where it can spread and establish itself. This plant is drought-tolerant, salt-tolerant, and deer and rabbit-resistant, making it ideal for challenging environments. The Black-Eyed Susan is well suited to wildflower gardens, pollinator gardens, as well as slopes, banks, and naturalized areas

As a perennial, it dies back to the crown each winter, it will regrow from the base in the spring. Avoid disturbing the crown during late winter to ensure healthy growth the following season.
