Description

Rhododendron ferrugineum may grow up to 1.5 m (4.9 ft) tall and produces clusters of pinkish-red, bell-shaped flowers throughout the summer. The undersides of the leaves are covered in rust-brown spots, which give the species the second part of its binomial name (ferrugineum, Latin for 'rust-coloured, ferruginous'). This is in contrast to Rhododendron hirsutum, which has no such brown colouring, has hairy edges to the leaves and grows over limestone. Where the two species co-occur (usually on soils of intermediate pH), the hybrid Rhododendron × intermedium may occur; as its name suggests, it is intermediate in form between the two parental species.

Habitat

Rhododendron ferrugineum grows primarily on acidic siliceous soils, whereas its close relative Rhododendron hirsutum grows on basic carbonate-rich soils. These two types of soils frequently occur near each other in the Alps.

Toxicity

Rhododendron ferrugineum is moderately toxic, containing arbutin, arecoline and rhodoxanthin, and can cause vomiting, and difficulties of the digestive, nervous, respiratory and circulatory systems.[1]
