Rhododendron augustinii ssp. hardyii | White Augustine's Rhododendron

$0.00

DESCRIPTION
Rhododendron augustinii ssp. hardyii is an evergreen shrub with a loose, upright habit and narrow, glossy green leaves that give it a refined appearance. In mid to late spring, it produces trusses of open, funnel-shaped flowers that are clear white, marked by a soft yellow to pale green throat with delicate spotting, adding subtle detail without altering the clean white presentation seen from a distance.

This subspecies is native to western China and was collected and introduced into cultivation in the early twentieth century. Plants grown from original collections have shown consistent floral traits over decades. Its spring bloom, airy branching, and elegant foliage make it well suited to woodland gardens, species collections, and lightly shaded borders where subtle flower coloration and form can be appreciated.
