Rhododendron ‘Haaga’

Rhododendron 'Haaga': Deep Pink June Trusses with a Spotted Throat

Rhododendron 'Haaga' is a profuse-blooming, hardy rhododendron that brings bright, deep pink colour right as spring transitions into early summer. In June, it opens slightly scented trusses, each bloom marked with a darkly spotted upper petal that adds richness and detail up close. The upright, mounded habit gives it a strong, well-shaped presence in the landscape, while evergreen foliage keeps the plant looking full and structured year-round. It’s an excellent choice for part-shade gardens that want dependable colour with a polished finish.

Plant Characteristics:

• Height: 5’
• Spread: 5’
• Flower Colour: Bright deep pink with a darkly spotted upper petal
• Flowering Period: June
• Foliage: Evergreen, deep green foliage
• Sunlight Requirements: Part Shade
• Soil Requirements: Moist, well-drained, acidic soil rich in organic matter

Uses and Benefits: A strong anchor shrub for woodland borders, shaded foundation plantings, and mixed evergreen groupings where you want a vibrant early-summer bloom moment. The deep pink trusses brighten dappled light and pair beautifully with conifers and other broadleaf evergreens, while the upright mounded habit helps create a layered, established look. Its lightly scented flowers also add a welcome sensory detail near paths and seating areas.

Care Instructions: Plant in acidic, organic-rich soil and mulch with pine bark or shredded leaves to keep roots cool and evenly moist. Water regularly during establishment and during dry spells, especially in summer heat or under trees where soil can dry quickly. Prune only lightly right after flowering, removing spent trusses and any winter-damaged stems, and avoid heavy pruning that can reduce next year’s bloom. Shelter from harsh winter wind where possible helps protect foliage and flower buds.

History: 'Haaga' is a University of Helsinki hybrid, selected for strong garden performance and dependable flowering in cooler climates. It’s valued for its profuse June bloom, saturated deep pink colour, and the distinctive spotting on the upper petal that gives each truss extra character.

Final Thoughts: If you want a rhododendron that blooms generously in June and holds a neat, upright shape year-round, Haaga delivers confident colour and evergreen structure with an elegant, shade-garden presence.
