Native Evergreen Shrub
Rhododendron catawbiense ‘Chionoides’- Mountain Rosebay
Rhododendron catawbiense ‘Chionoides’ is winter hardy to USDA Zones 4-8 where it is best grown in acidic, humusy, organically rich, evenly moist, moisture-retentive but well-drained soils in part shade. Performs well with some morning sun but needs shady afternoon conditions. Tolerates close to full shade. Prefers cool summer temperatures. Roots must never be allowed to dry out. Acidify soils prior to planting and thereafter as needed. Plant in locations protected from strong winter winds.
Do not site plants within or near the drip line of trees in the walnut family (most rhododendrons are sensitive to toxic juglones produced by roots of walnuts, butternuts, pecans and hickories). Good soil drainage is essential (doesnât like âwet feetâ). 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. All parts of this plant are highly toxic if ingested.
