A unique shrub/tree that is found in the plateau country of the southern Rocky Mountains. A true xeric plant that has thick leathery, blue-green leaves that have wavy margins—a real conversation piece! Our oak friends tell us that there are seven ancestors in this natural hybrid. The Cheyenne Experiment Station has one that is doing very well after some 70 years. This one is a character of the windswept west—it decides which way it will grow, upright like a tree or outward like a shrub! These oaks have become such pets for their people that each gets named when planted!
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.
