Wildlife Attraction
|
– Attracts bees, bumblebees, and some butterflies during bloom period
– Evergreen foliage offers low shelter for small birds |
Self-pollinating
|
|
Seasonality
|
– Evergreen: Provides year-round structure and foliage
– Flowers in late spring; maintains interest through all seasons due to foliage |
Ideal For
|
Foundation planting – woodland gardens – shade gardens – north or east-facing beds – mixed borders – mass plantings for evergreen structure |
Leaf Description
|
– Dark green, leathery, elliptic evergreen leaves, 3–4" long
– Foliage is dense, creating a full and refined form year-round
– Slightly glossy finish adds year-round interest even in winter |
Flower Description
|
– Produces large trusses of pure white flowers, each with a faint yellow dorsal blotch
– Blooms are slightly ruffled and measure about 2.5–3" wide
– Flowers appear in late spring (May to early June)
– Highly ornamental and striking against the dark foliage |
Planting Instructions
|
– Plant in spring or early fall to allow roots to establish before heat or frost stress
– Choose a site with well-drained, acidic soil (pH 4.5–6.0) rich in organic matter
– Dig a hole 2–3 times wider than the root ball and as deep as the container height
– Backfill with a mixture of native soil and compost or peat moss
– Avoid planting too deep; the root flare should sit just above soil level
– Apply a 2–3" layer of mulch to retain moisture and insulate roots, keeping it clear of the main stem |
Pruning & Maintenance
|
– Prune lightly immediately after flowering to maintain shape and encourage branching
– Remove dead, damaged, or crossing branches at any time
– Avoid heavy pruning into old wood; rhododendrons don't readily resprout from bare stems |
Water Needs
|
– Requires consistent moisture, especially in the first two years
– Keep soil evenly moist but not soggy; avoid letting roots dry out
– Benefits from drip irrigation or deep watering during dry periods |
Light Needs
|
– Prefers partial shade—ideal is filtered morning sun with afternoon shade
– Tolerates full shade but may flower less; avoid full sun in hot climates to prevent leaf scorch |
Harvesting
|
– Not grown for harvest; flowers are ornamental only and not typically cut for arrangements
– No significant use for harvesting in home gardens |
Fertilizing
|
– Use a slow-release, acid-loving plant fertilizer in early spring just before new growth begins
– Avoid overfertilizing—excess nitrogen can reduce blooms and damage roots
– Supplement with chelated iron or sulfur if leaves yellow (chlorosis from alkaline soil) |
Pollination
|
– Self-fertile but can cross-pollinate with nearby rhododendrons for seed production
– Flowers are visited by bees and other pollinators, though fruiting is uncommon in garden settings |
Companion Plants
|
– Hosta – provides contrasting foliage in shade gardens
– Ferns – enhance woodland settings with complementary textures
– Heuchera – adds color contrast with bold foliage
– Pieris japonica – shares similar soil and light needs
– Hydrangea macrophylla – balances form and bloom timing
– Astilbe – thrives in moist shade and adds soft floral texture nearby |
