Central Ohio soils are not the best for growing many acid-loving plants, but with a perfect location, lots of soil amendments and some luck, a gardener could grow the beautiful 'Nova Zembla' rhododendron (Rhododendron 'Nova Zembla').

This broadleaf evergreen has glossy, thick leaves that are elliptical in shape and dark green in color. The dark-brown stems thicken and becomes scaly as it ages.

The large flowers are the prize; they are red with maroon spots, and appear a brilliant raspberry in bright sunlight.

This rhododendron is a strong grower; it is cold tolerant and does need to be sheltered from winter winds.

Rhododendrons have a fibrous root system, and should not have other plants growing under them.

The Nova Zembla thrives in moist, well-draining soils that are rich in compost and have a pH in the 5-5.5 range.

See the glorious flowers of the Nova Zembla rhododendron in the Himalayan Biome at Franklin Park Conservatory and Botanical Gardens.
