A serene, tranquil setting is the trademark of one of the world's largest indoor gardens but it's also a great place for kids of all ages, too. The Elizabeth Morse Genius Children's Garden is open during normal hours. As kids enter the garden they are greeted by a giant, meandering vine with larger-than-life sized roots. A 7-foot-tall seed begs to be climbed (climbing is encouraged) and kids love to touch the Sensitive Plant which is so shy it cringes when touched. Another favorite is the Balsa Tree which emits a hollow sound when its trunk is tapped. The youngest set have their own place to explore colors and textures of soft-form blocks and play rings in the special permanent Crawling Area.
