Picea pungens 'Argentea' / silvery Colorado spruce

Picea pungens 'Argentea' is a collective designation given to myriad clones of Colorado spruce that flush with silvery-white new foliage in spring. Since no specific clone can be identified as the parent of this cultivar, 'Argentea' should no longer be used as a cultivar name, rather be delegated to varietal status, i.e. Picea pungens var argentea.

This cultivar name was coined by D.A. Rosenthal in 1887, in Synopsis Plantarum Diaphoricarum.
