Swamp Rose Mallow (Hibiscus)

Swamp Rose Mallow (Hibiscus) has large white-pink showy flowers which attract hummingbirds and pollinators to your yard. It is a tall, fast growing perennial shrub. The flowers typically only last 1-2 days, but the plant will continue to rebloom throughout the season.

This hibiscus tolerates heat and humidity but does not do well when exposed to wind. Make sure the plant has access to lots of moisture for better flowering.

The Swamp Rose Mallow (Hibiscus) is also known as the dinner plate hibiscus because it can grow incredibly large flowers, as big as dinner plates.

Harebell is a native perennial wildflower known for its bell-shaped, blue-violet flowers. The noddling blooms occur in clusters at the top of slender stems. Blooming in bursts from summer to fall, the flowers attract pollinators such as butterflies, bees, and hummingbirds.

Regular deadheading encourages additional blooms, extending its floral display through the season. Harebell prefers areas with cooler summer climates and does poorly in those that get too hot and humid. It is well suited for native wildflower gardens, pollinator gardens, and naturalization projects.

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.
