Seldom found above 3,000 feet elevation, the rank-smelling Arrowweed forms dense, willow-like thickets in stream beds and in moist, saline soils. It is common in moist locations from Texas to southern Utah and south into California and Mexico; usually in pure, dense stands.
The green foliage gives off an agreeable odor, but when the plant dries this becomes rank and unpleasant, clinging to the plant long after it has been cut. This odor is often a characteristic of native dwellings where Arrowweed has been used as a ceiling mat above the rafters.
Arrowweed is browsed by deer, and sometimes by horses and cattle. The straight stems were used by Indians in making arrowshafts, and are still important as a construction material in the walls and roofs of mud huts. The stems are used, also, by desert Indians in basketmaking, and in fabricating storage bins and animal cages. From the foliage of the stem tips, Pima Indians brewed a tea which they used as an eye wash.
The flowers are reported to furnish considerable nectar gathered by Honeybees. The blossoms are inconspicuous and develop into tawny-tufted seed-heads.
PURPLE
Mimulus bigelovi
Common name: MONKEYFLOWER Arizona and California deserts: (Mimulus bigelovi). Red-purple. February-April. Texas desert: (Mimulus glabratus). Yellow. June. Figwort family. Size: Branching, creeping annual up to 8 inches.
Disproportionately large flowers for the size of the low-growing, small-leafed plant make it particularly conspicuous in the open, sandy locations where it blossoms in the springtime.
Although the Monkeyflower is usually thought of as moisture-loving, there are a number of desert species. The flowers are quite easy to recognize, as they closely resemble the Monkeyflowers which grow in the moist places surrounding seeps and springs, and they also are somewhat similar in appearance to their close relatives the Snapdragons and Pentstemons.
