Hollis Garden is a public botanical garden in Lakeland, Florida, in the United States.
It is divided into 16 themed sections or "rooms" with plantings being rotated throughout the year. Not all of the rooms feature heavy planting, for example the Gazebo and Trellis area displays Tuscan style, neoclassical architectural design elements. Some of these rooms showcase water features such as the Grotto, a shady section of garden that houses tropical ferns and orchids; the Rosette Plaza and Fountain, a grand, central, open-spaced display; Bowls and Runnels, a long gravity-fed fountain that takes water from the Rosette Fountain down to Lake Mirror; and the Lily Pond, a small secluded koi pond surrounded by rustling bamboo. There are rooms named after their colors including the Red, Yellow, and White Rooms. Other rooms are named after their planting types like the Vegetable Room, Tropical Room, and Herb Rooms, and Patterned Flowerbeds. Two of the rooms, Sustenance Orchard and Trees of Americana, showcase the botanical heritage of Florida and the United States. The trees in the Trees of Americana Room are all relatives of famous trees of American history including a Water Oak from Helen Keller's home, a Sycamore from Susan B. Anthony's grave, an Oak from 16th U.S. President Abraham Lincoln's birthplace, a Weeping Willow from the musician Elvis Presley's front yard, and, previously, a tree associated with the poet Edgar Allan Poe, which died. Lastly, the Butterfly Garden is designed and dedicated to the local pollinators such as butterflies, moths, and bees. The rooms and areas are connected by labyrinthine walkways that connect the garden to the surrounding Lake Mirror complex. The staff maintain a growing collection of plants from around the world including several incense plants like the Frankincense Tree and the Balm of Gilead, and edible plants like the Blackberry Jam Fruit and the Peanut Butter Fruit.
