A wide variety of plants can be found, including majestic 40′ tall palms, carnivorous plants, 10′ cacti, and succulents. The rose maze is in bloom from June to September and the outdoor perennial gardens bloom with color from spring to fall. Visit the calendar to view special events, workshops, and other activities. Indoors or out, the Center is a magical place to visit in the heart of beautiful Roger Williams Park.
