Built next to the Mississippi River, the Quad City Botanical Center offers beautiful gardens in all seasons. The center is located at 2525 Fourth Avenue (just off Hwy 92) in downtown Rock Island. This gardener's dream destination offers a 6,444 square foot tropical Sun Garden conservatory, the outdoor Conifer Garden featuring one-of-a-kind conifer trees, and a medley of perennial gardens.

The signature tropical Sun Garden is one of the world's most unique conservatories. This garden features islands of gardens, a beautiful 14-foot waterfall, reflecting pools with Japanese Koi fish, and a 70-foot skylight peak with ferns, palms, bromeliads, orchids, frangipani, bird of paradise, banana plants, and other exotic tropical wonders.

Each season brings a change in the garden scenery - thousands of bulbs in the spring, hundreds of colorful flowers in the summer, rainbows of hardy mums in the fall, and tropical blooms and twinkling lights in the winter.
