Creosote Bush (larrea tridentata)
Creosote covers vast areas of the southwestern deserts with its drab, avocado-green foliage. Named for its resinous odor, the creosote bush is found on gravelly slopes. Its many slender, 3-12 inch stems bear small, waxy leaves; each composed of 2 pointed leaflets. The 1 inch flowers, blooming in April and May, are bright yellow, with five petals, each twisted like a propeller blade. The fruits are white fuzzy “seed-balls”.
