Plant Select® 2001. This is the only mock orange at the Experiment Station in Cheyenne that was prospering after years of neglect! Perhaps that is because this native western strain is suited to growth on alkaline soils (doesn’t get chlorotic) unlike many of the eastern or developed varieties. This tough but beautiful shrub named after Meriweather Lewis has dense racemes of 1-1.25 inch pure white flowers in early summer that provide sweet orange-blossom like fragrance. Use it where you will get to see and smell it but not where reflected heat will be a challenge.
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.
