Waxy skin - some leaves have a thick, waxy skin on their surface. This reduces water loss by transpiration . Water storage - some plants, known as succulents, store water in their stems, leaves, roots or even fruits.
The waxy covering on plant leaves, young stems, and fruit is called the "cuticle". ... The purpose of this covering is to help the plant retain water. In arid regions, that is very important. In wetter regions, the waxy coating may help prevent infection by disease organisms.
Plants that grow in arid zones of USDA zones 9 to 11 use waxy leaves to limit transpiration and retain water but also to protect leaves from the frigid temperatures sometimes found in the desert. Trees like the desert willow (Chilopsis linearis) have narrow, waxy leaves and striking purple flowers.
