Coyote bush is most likely found in coastal scrub and lowland zones. The scientific name for it is Baccharis pilularis, but the bush is also called chaparral broom. The bush is an important part of chaparral environments, providing food, shelter, and erosion control in scrubby land with few large trees. The amazingly adaptable plant is found in canyons, hillsides, and bluffs. Try growing bush baccharis as part of your natural landscape in parts of Oregon, California, and coastal areas below 2,500 feet (762 m.).
An interesting note about coyote bushes is their close relation to sunflowers. The plant is scraggly and wiry, with stiff branches and small, grayish serrated leaves along the woody stems. An herbaceous perennial, coyote bush has evolved several adaptive strategies to thrive in poor soils with loose vertical soil. It has a wide root system and waxy leaves, which protect it from moisture loss.
Chaparral zones frequently experience wildfires to which the plant is equally well adapted. Leaves are coated with a resinous substance that retards fire. In addition, the thick dense roots and stout crown help the plant regenerate after the upper growth has been consumed in a fire.
The bush tends to grow in areas with sporadic rainfall and extended dry seasons. It may be a low-growing shrub or an erect tall bush, depending upon its growing conditions. Those that hug hillsides tend to grow low to the ground for protection.
Where a site provides shelter, coyote bush looms taller and stretches for sunlight. These bushes can withstand drought, infertile soils, fire, and salt spray. Growing bush baccharis provides erosion control with its wide branching roots and requires little maintenance once established.
Baccharis is a native plant and has been used for several purposes by indigenous people. If ingested, the bush does have the ability to cause pregnancy termination.
Native people used it as a material for hunting tools, such as arrow shafts. The fluffy female seed heads were part of stuffing for toys and other items.
Coyote bush uses also extended to some medicinal therapies, such as using heated leaves to reduce pain and swelling.
If you are seeking a natural addition to your landscape or back forty that will require little effort on your part, coyote bushes are right up your alley. Provided soils are moderately to heavily coarse, the plant performs well in a variety of situations.
Coyote bush does need a sunny location and frequent watering until it is established. Once the plant is situated, however, you don’t need to water it except in the most severe droughts.
Trim the bush as needed to keep it from getting too rangy. This is a slow-growing plant with the main gains achieved in spring when temperatures are warm and rains give it a burst of growing moisture.
Baccharis plant care is minimal and the bush may reward you in spring with tiny flowers that become cottony, fluffy seeds in fall.

Distinguishing traits. Coyote bush is a low-lying shrub with dense foliage and wiry branches. Year-round it’s covered with medium green, jagged-edged leaves. Their waxy appearance is due to a coating that prevents moisture loss from evaporation. The leaves can get sticky during hot summer days, but they're also fire retardant.
Coyote bush’s form reflects its survival needs, depending on the climate . It's low and dense along the coast in harsh windy conditions and more of an upright shrub in protected inland canyons .
The shrub produces inconspicuous flowers (white fluffy female flowers and yellow male flowers) from autumn through winter. Following flowering, the female plants go to seed, sending pappi into the wind. Most nurseries sell the male plants, as those won’t produce seeds or make the same mess.
How to use it. Plant coyote bush for its wildlife value. Its nectar feeds native and nonnative bees and insects, and its branching provides a shelter and habitat for wildlife. The standard form and 'Pigeon Point' cultivar are mixed in the hillside restoration project shown here.
Planting notes. Coyote bush is considered a common plant by many, with cultural tolerance and resilience. It prefers well-drained soil, like those at the coast, but overall it is soil tolerant. It can handle direct salt spray, fog and wind — coastal conditions — and requires no supplemental watering. It is, however, more fire retardant and lush if watered monthly in inland climates.
Coyote bush does best given full sun and enough room for its extensive root system to spread. It is a plant that is quick to regenerate after fires, floods or clearings pruning periodically thins the plant out and maintains its shape in a process that mimics nature's.
Coyote bush (Baccharis pilularis) is a broadleaf evergreen shrub growing 2 feet high and 6 feet wide. The wedge-shaped, oblong green leaves create a dense bush of foliage. Coyote bush comes in male and female shrubs. The female bush produces white flowers and the male bush produces yellow flowers. These flowers form tight clusters. This drought-resistant bush is commonly used for erosion control and is native to the Oregon coast.

I love this plant, I have two varieties of the same plant. One is lower growing and greener and does not spread super rapidly but still fast(not invasive). The other I got from seed I took, and it grew fast and is now flowering, it is more lime colored and spreads faster and gets taller.
It was under water in a flood the first year and spread. It now seldom cares if I water it or not and I have caleche soil, not ammended there and somewhat alkaline too.
Partners well with Atriplex C. took the same conditions and water needs then and now. (fast as well)

This is the upright form of native Baccharis, male and female plants (small white flowers). Drought tolerant, but grows well with irrigation. 3-8' tall, deer proof, blows in on the wind.
Only male plants will likely be found in the retail market. If Baccharis pilularis is used for ecological restoration of wildlands, female plants should also be incorporated into the planting scheme.

Also known as the dwarf chaparral broom, although I have no idea why. :) Established plants are drought tolerant. Can be pruned in late winter to "clean the plant up".
There are several similar Baccharis species that form large shrubs or small trees. Groundsel tree, in the Asteraceae (daisy) family, is a native shrub to the coastal areas of the eastern US. It is commonly found in salt marshes, sandy locations, wet disturbed sites, near a road, fields, and is occasionally sold in the nursery trade for its unique foliage and flowering season.
This plant is commonly seen as a multi-trunked plant with an irregular, open, airy habit that can become leggy. As a seedling it resembles lambsquarters. In the fall and winter, plants may be covered with white to cream-colored flower heads. Seeds are shed in late fall or winter, but the seeds of the female plant (this plant is dioecious) are poisonous. Wind dispersed seeds blow into landscapes during the winter months and the seeds easily grow (because they do not mind the shade when seeds first start growing), making this a weedy plant.
Plant in the full sun to partial shade in a range of soil types, even poor fertility, wet sites, and dry soil. Heat, drought, waterlogged soils, and salt spray are all tolerated. It may even be seen growing in a place after a fire: therefore, it is very weedy because it can grow in many conditions. Though it is not commonly used as a landscape plant, if you are to plant it, it is best used as filler or on the edge of a natural area.
Baccharis is dioecious: male pollinator plant needed for female fruit set. Female fruits are very showy. It can be an aggressive grower in agricultural/silvicultural situations it has spread inland along salted roads.
Insects, Diseases, and Other Plant Problems: The wood is brittle. It can be weedy and if undesired, the seedlings are not well controlled by preemergence herbicides, and selective postemergence controls are not available. Hand pulling seedlings when small is the best option for removal. Also, the seeds of the female plant (this plant is dioecious) as well as the leaves in general are poisonous.(Greensboro, NC)-Mid Fall Douglas Goldman, USDA CC BY-NC 4.0 (Greensboro, NC)-Mid Fall Douglas Goldman, USDA CC BY-NC 4.0 feathery seeds Bob Peterson CC-BY-SA 2.0 fall habit Cotinis CC BY-NC-SA 2.0 habit Forest & Kim Starr CC BY 2.0 leaves Homer Edward Price CC BY 2.0 Habit J.
