Permaculture Plants: Rubber Rabbitbrush, Ericameria nauseosa



Rubber Rabbitbrush (Chamisa)
Ericameria nauseosa (Chrysothamnus nauseosus)
Asteraceae (Compositae)

This is the primary source of golden-yellow in much of the west during the late summer and early fall. When it is not blooming many people mistake it for sagebrush, but once you take a good look at the flowers it is hard to make that mistake again.

Growing Conditions

USDA Hardiness Zone: 3-7, maybe higher. Similar width

Drought Tolerance: Very good

Soil: Best on well drained alkali soils, but flexible with other soils

Light: Full sun

Native Range: From North Dakota south to Texas and all points west. 

Potentially Invasive

Permaculture and Homesteading Uses

Yellow Die: A very warm yellow gold yarn can be made using Rabbitbrush.

Pioneer Plant: Rabbitbrush is an aggressive pioneer plant at home in rough and tumble roadside areas as well as any other disturbed area. If this does not grow in you area it is because your conditions are to nice for it or because it has never been tried. Use this plant in areas regions where it is already established because it will push out other pioneer plants in places it is not native to.

Soil Builder: When the leaves fall they build up in piles under the plant and enrich the soil. When the soil becomes sufficiently enriched Rabbitbrush will often dieback and give its position to more delicate and slower growing plants. 

Late Honeybee Finisher: Rabbitbrush is one of the latest blooming plants available in its home range. The honey is said to be strong and an acquired taste, but most beekeepers have already harvested by the time it blooms so it usually gets left to the bees. 

Nutrient accumulator: Since there are few roots near the surface there is an excellent chance Rabbitbrush is a top notch nutrient accumulator.

Appearance

Flowers: Golden-yellow, late August through October

Leaves: Dusty gray or dusty green, narrow and long--resembling a rabbit's ear, deciduous to semi deciduous 

Size: 1-8' tall

Roots: Deep with few feeder roots near the surface

Fruit: Achine

Pests: Nothing serious known

Ethnobotany

Used as a medicinal tea, yellow die, chewing gum.

Comments:

This is a tough plant for tough areas and so common it is nearly invisible to many people that pass it every day. This is surprising because as an ornamental it has drop dead color and needs very little maintenance. Rabbitbrush can be made into a high grade rubber, but it is not cost effective at this time.

  1. Rubber Rabbit brush is too weedy. True at this time of the year it is very attractive. When it is pruned to about four inches from the ground, the growth the next spring is lush and attractive. I dig most of mine up each year.
