Black-Eyed Susan

Twinflower is a native, trailing evergreen ground cover known for its delicate flowers that grow in nodding pairs. These pale pink blooms are described as being sweetly fragrant, attracting native bees and other pollinators.
Growing in cool, moist, acidic soils, the trailing stems form roots as they spread and start to form mats across the forest floor. Due to its woody stem, it is technically classified as a shrub and often referred to as a subshrub or dwarf shrub. This species is well-suited for naturalization, restoration, and conservation projects.
Twinflower (Linneae borealis) was named in honour of Carl Linnaeus, who adopted it as his personal emblem.

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.
