White Lights Rhododendron is part of the Northern Lights Series, cold hardy, and deciduous. In late spring you'll be drawn to its fragrant white blooms. In fall, the foliage turns a beautiful purple-bronze color. Pruning is recommended after the flowers are spent to control the size and shape of this shrub.

White Lights Rhododendron should be your next hedge/screen, or plant it on its own as a specimen plant.

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.
