Delicate and graceful in form, Larrea tridentata (Creosote Bush) is an evergreen shrub of open-branching habit with slender, erratic stems bearing tiny, resinous, dark green leaves composed of 2 leaflets. Using radiocarbon dating and known growth rates of creosote, scientists have estimated the age of “King Clone” as 11,700 years. Gas 8. As the shrub grows, branches continue to originate around the periphery of the original stem crown. The plant has now become a clone, composed of several independent stem crowns all descended from one seedling. Lowe: LAGL11: Larrea glutinosa Engelm.

As growth continues, the oldest branches gradually die and the stem crown splits into separate crowns. It is a genus of flowering plant that belongs to the Zygophyllaceae family. Eleven to 12,000 years ago, at the end of the Ice Age, this area would have been dominated by juniper woodland and lots of grass. One method counted rings and measured the distance of annual growth, and the other used radiocarbon dating on pieces of wood found in the center of the ring, and measuring their distance from each other and the living bushes. One doesn't have to look far to see a wonder of the plant world in Joshua Tree National Park. Diabetes 7. The species is hermaphrodite (has both male and female organs).
