Swamp Rose Mallow (Hibiscus)
Silky Lupine

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.

Silky Lupine is a native perennial wildflower known for its upright spikes of blue to violet flowers. Blooming from late spring into summer, the nectar-rich, showy blossoms attract a variety of pollinators, especially bees and butterflies. The plant’s fine, silky foliage provides soft texture and visual interest, enhancing landscapes throughout the growing season.

Silky Lupine is a nitrogen-fixing plant that enriches soils and supports surrounding vegetation. Its deep roots stabilize soil, and it spreads naturally by ejecting seeds from drying pods. If spread isn’t desired, new seedlings are easy to remove. While it is foraged by some wild animals, it contains alkaloids that are toxic to livestock. Silky Lupine is well-suited to pollinator gardens, naturalization plantings, erosion control, and ecological restoration projects.
