  • Plants found in the Desert Garden have succulent, water-storing stems, leaves, or roots. They are adapted to survive heat and long periods without rain.
  • See the vertical lines with spines on the cactus pictured at right? These are called ribs. These ribs can expand to help the barrel cactus store water.
  • The largest barrel cactuses in the garden can weigh hundreds of pounds, and some are more than 100 years old!

Activity

Adaptation art: Think of a plant that grows in the desert and make an adaptation for the plant. Maybe it changes color for camouflage? Maybe it has built-in sunglasses? It is up to you. Use colored pencils, crayons, or markers to draw your desert plant. Think about how your adaptation will be helpful for the plant and its ecosystem.
