+This native of the Black Hills is right at home in the plains and basins of Wyoming! Describing this tree is like describing a warrior. Early in its life it will tend to be pyramidal and as it matures it will develop into a tall tree with a massive trunk and very stout branches. Bark is rough and deeply furrowed. The leaves are a dark green on top, gray-green beneath. Acorns up to 1 inch are enclosed by a heavily fringed cap and prized by wildlife. Withstands drought, wind, extreme cold and heavy soils. Let this warrior be a part of your landscape!
Throughout this site, the following are used as guidelines for watering established plants:
These truly xeric plants can live with our 12 inches of natural annual precipitation and only need a winter watering during a multi-year drought, but they will thrive with a monthly watering. Overwatering will kill some of these. These plants are adapted to intermittent deep
watering with soil drying to a depth of a few inches between waterings. Watering frequency may be every couple of weeks during the active growing season and maybe only one winter watering for optimal care. These plants need regular watering somewhat like a bluegrass lawn so that
they never dry to depth in the root system during the active growing season, and need occasional winter watering to prevent root dessication and resultant plant
death. About sizes of our plants:
Sizes indicated with a # are roughly the equivalent in gallonage; so a #2 is about a 2 gallon pot size; b&b stands for balled and burlapped.
