Epicuticular wax

« Back to Glossary Index

Epicuticular wax (Ep-i-cyoo-TI-cyoo-lar wax) is a natural, waxy coating some plants develop on leaves, stems and fruits. Forming on the outer cuticle of the plant’s skin, it provides protection from water, insects, dirt, moisture loss and UV rays. On succulents, the wax appears as a whitish film, sometimes described as farina, farina bloom or glaucous leaves.
