Rhododendrons are reliable, beautifully flowering, evergreen shrubs of variable origin: S.W. China, Himalayas, Northern America, and even Europe. The original species were hybridized several times for better performance so in the 1950´s there were more than 10,000 cultivars registered, and the number keeps increasing.

Catawbiense „Grandiflorum“ is a popular, fast-growing hybrid that can easily grow 2m tall and wide, and even more. It has upright, regular trusses of lavender-lilac flowers with red flare. Sun and wind tolerant.

For richer flowering and growth dead-head where possible. The roots are shallow, spreading to sides in search for nutrients. Never plant them too deep. The soil has to be acidic (pH 4.5-5.5), rich in humus, cool and always moist. Ideal soil mixture is peat with lime-free, light garden soil topped with leaf-mould. Fully hardy to min. -29°C (USDA zone 5).
