Swamp Rose Mallow (Hibiscus)

Slough Grass is a hardy grass that will happily grow in any wet soil. It is usually found near water and is common haymaking material or forage.

Slough Grass is also useful for erosion control and land reclamation.

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.
