About plant names...

Creosote bush is an abundant native of arid parts of North America. These long-lived plants gradually spread out, with central portions dying and outlying portions eventually separating, forming clonal colonies. Taken together, these colonies are extremely long-lived. At 11,700 years old, the “King Clone” creosote colony is the oldest living organism on Earth.

Identification: Plants form irregular bushes up to 10' (3 m) high, but usually closer to half that; the size is proportional to the amount of available water. Yellow flowers are ¾-1" (1.9-2.5 cm) around, with five twisted petals. Seed pods are oval, surrounded by a silvery white fuzz, about ¼" (6.3 mm). Leaves are yellow-green or dark green and shiny, each consisting of two teardrop-shaped leaflets ½" (1.3 cm) long and ¼" (6.3 mm) wide. The two-leaflet leaves grow in opposite pairs, so it looks as if there are four tiny leaves at each node along the branch. Plants give off a characteristic odor when wet or broken.
