Rhododendron callimorphum ssp. myiagrum

Large-leaved Rhododendron

Rhododendron callimorphum ssp. myiagrum is an evergreen rhododendron with a compact shrub form and rounded to broadly oval leaves. In mid to late spring, it bears bell-shaped flowers that are usually white to blush or rose-pink, typically marked with a subtle basal blotch and sometimes faint flecking. The bloom clusters sit close to the foliage, giving a refined, tucked-in floral display that suits woodland borders and rock-garden settings.

Design tip

Give this rhododendron a prominent role among rocks or other strong garden features, where its compact form can balance their visual weight. Keeping nearby planting relatively simple allows its rounded silhouette to remain distinct rather than disappearing into a crowded collection of shrubs.
