Big Sagebrush (Tridentata) is generally described as
a perennial tree or shrub.
native to the U.S. (United States)
has its most active growth period in the
spring and summer .
The greatest bloom is usually observed in the
with fruit and seed production starting in the
summer and continuing until
retained year to year.
Big Sagebrush (Tridentata) has a
long life span relative to most other plant species and a
slow growth rate.
At maturity, the typical
Big Sagebrush (Tridentata) will reach up to
4 feet high, with a maximum height at 20 years of
Big Sagebrush (Tridentata) is easily found in nurseries, garden stores and other plant dealers and distributors. It can be propagated by
bare root, container, seed.
It has a
slow ability to spread through seed production and the seedlings have
Note that cold stratification is
not required for seed germination and the plant cannot survive exposure to temperatures below
high tolerance to drought and restricted water conditions.
Uses of : Landscaping, Medicinal, Culinary, etc.
Livestock: The leaves are high in protein but the bitter resinous taste prevents extensive grazing by cattle. Sheep will eat young plants and new growth readily when other forages are dry. They will also make considerable use of the plant in the winter.
Wildlife: Sage grouse are the heaviest users of sagebrush. As much as 70 to 75 percent of their diet is made up of foliage and flower clusters of the plant. Antelope eat substantial amounts of sagebrush throughout the year, and mule deer feed heavily on the plant during late fall, winter, and spring, particularly if other foods are covered with snow. Sharp-tailed grouse, jackrabbits, elk, and many species of small mammals eat sagebrush sparingly during various times of the year. Sagebrush provides nesting cover for sage grouse, and to a lesser extent pheasants and several species of prairie sparrows. It provides loafing and escape cover for sage grouse, chukar, sharp tailed grouse, gray (Hungarian) partridge, pheasants, quail, jackrabbits, and deer.
Big sagebrush and its subspecies, are tall, rounded, U.S. native shrubs with short branched, woody trunks. The height is normally about 4 feet, but varies from 2 feet in arid conditions to as high as 15 feet on favorable sites. The winter persistent leaves are wedge to fan-shaped and are usually three-lobed at tips. They are strongly aromatic. Buds form about June with flowering and seed formation in the fall.
Required Growing Conditions
Big sagebrush is drought tolerant but cannot stand excessive sub-moisture. It grows on moderately shallow to deep, well drained, sandy to silt loam soils of neutral to slightly alkaline reaction. Big sagebrush occurs on practically all range except meadows and at high elevations.
Big sagebrush is distributed throughout the western United States.
Cultivation and Care
This has not been a factor to date since its value hasn’t been considered great enough. Control has been more important. It is a good seed producer and increases rapidly when soil is disturbed in its natural habitat. Livestock over-grazing can also promote the increase of big sagebrush populations.
General Upkeep and Control
Control is accomplished by chemical sprays, fire, railing, chaining, and beating. Good range management of deep-rooted perennial grasses is a control measure.
