Rhododendron mollis

Mollis Azalea, Late Midseason Azalea, Deciduous Azalea


Extraordinarily eye-catching, Rhododendron mollis are hybrid deciduous Azaleas with lush and large clusters of 7-13 flowers in striking shades of yellow, orange, salmon, pink or white in late spring or early summer. More compact and spreading than the other hybrid Azaleas, they are cold-hardy and can withstand temperatures down to -10°F (-23°C). While not as hardy as the Ghent hybrids, their blooms are larger and they are also more heat tolerant. Originally developed in Belgium and Holland, they also provide attractive fall color, with their fresh green leaves warming up to terrific multicolor shades as the season changes.

  • Grow with a compact, rounded habit, up to 4-6 ft. tall (120-180 cm) and 4 ft. wide (120 cm). These shrubs grow at a slow rate, with height increases of less than 12 in. (30 cm) per year.
  • Sun to part shade lovers, these plants are easily grown in moist, acidic, humusywell-drained soils. Will do well in considerable sun, but have a preference for bright shade, filtered sunlight, or morning sun, and can even do fairly well in somewhat deeper shade. Full afternoon sun could result in bleached leaves and shortened blooming period. Plant shallowly in a location protected from strong winter winds. Protect from frost to prevent damage to flowers. Mulch annually with leaf mould to retain moisture, control weeds, and cool the soil.
  • Perfect for shrub borders or mixed borders, as a flowering hedge or privacy screen, foundation plantings and shade gardens. Great for small gardens too!
  • Attract butterflies, hummingbirds and birds
  • Removing spent flowers promotes new growth.
  • All parts of plant are poisonous if ingested.
  • Favorites cultivars are:
    Anthony Koster – with bright yellow flowers and a vivid orange blotch.
    Arneson Flame – with abundant, red flowers.
    Arneson Gem – with profuse golden flowers and orange edges on a compact plant.
    Christopher Wren – with brilliant yellow flowers flushed with red-orange. Vigorous.
    Dr M. Oosthoek - with vibrant orange-red flowers and leaves with silvery undersides.
