Highbush Cranberry

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.

Highbush Cranberry produces attractive white flowers in late June and bears edible fruit that matures to a bright red colour in the late summer.

This shrub, native to much of Canada, is fast growing, and its fruit can be eaten raw or cooked into a sauce.
