Quick Overview:

Rhododendron sinogrande is an evergreen understory tree or large shrub that is native to coniferous forests in alpine areas of western China, Tibet and Burma. In its native habitat, it will grow to as much as 50′ tall. Everything about this plant is big, including its glossy dark green leaves which grow to as much as 3′ long and its creamy white to pale yellow flowers (to 3″ wide) which bloom in trusses of 15-30 flowers in spring. The underside of leaves are pale brown to silvery white. Leaves are reportedly the largest found on any rhododendron.

Description

Winter hardy to USDA Zones 8-10 where it is best grown in acidic, humusy, organically rich, moisture-retentive but well-drained soils in part shade. Prefers a sun dappled shade. Foliage may scorch in full sun. Acidify soils prior to planting and thereafter as needed. Plant in a location protected from strong winter winds. Good soil drainage is essential (doesn’t like “wet feet”). Poor drainage inevitably leads to root rot, therefore raised beds/plantings should be considered in areas with heavy clay soils. Shallow, fibrous root systems (do not cultivate around plants) will benefit greatly from a mulch (e.g., wood chips, bark or pine needles) to help retain moisture and stabilize soil temperatures.
