Trusses of light lavender-pink flowers with attractive yellow/red pattern on dorsal petal. This rhododendron grows well in filtered to full sun and blooms mid late-season, so usually May to June. An incredibly cold hardy hybrid rhododendron, to -25°F when protected from windchill in fact. We suggest giving it room to grow as it can reach over 6' tall over time with the right conditions.
