A standout western native with wonderfully fragrant, orchid like white flowers borne in 4-8 inch panicles which appear in late June followed by 12-18 inch long thin seed pods! Its narrow canopy with large light green heart-shaped leaves makes this a perfect choice for those of you who want a tall tree in limited space. The first ones in Casper were planted in the 1920s but are rarely sold in the trade today. We introduced a few last year at our lot to gauge customer acceptance—and once they smelled the fragrance of this tree we knew we had a winner!
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.
