Blue Moon Wisteria is a striking, flowering vine, and the hardiest of the wisterias. Up to three times in one growing season you can expect showy, fragrant, lavender-blue flowers.

Make sure you plan your site as this vine requires a structure to support its mature weight. Try planting close to a post, trellis, or fence.

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.
