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.

Northern Catalpa is a striking feature tree with showy flowers, and very large leaves. Its orchid-like flowers are white with yellow and purple accents, and they have a pleasant fragrance. They bloom from late spring to early summer and can last up to two weeks, attracting hummingbirds and pollinators. The leaves are very large, ranging from 15-30 cm long, 12-20 cm wide, forming a canopy that makes it a good shade tree.

They can tolerate dry conditions as well as standing water, air pollution, and salt. These factors and its beauty contribute to its growing popularity as both a boulevard and ornamental tree in colder areas.

Northern Catalpa produces long bean-like capsules and are sometimes called the Cigar Tree in reference to this fruit.
