Assortment of Rhododendron-species

R. mucronulatum

           Rhododendron species  are originally growing in Asia, Europe and North-America. There are about 1.000 species , of which about 200 can be grown and planted in Western-Europ and comparable zones of about 7 or higher. The colder the area, (zones 6 to 4) the smaller the number of the species can be grown of course. And reverse!  The 'purists' of the rhododendron-lovers are especially interested in the species, of which many have fine habits like the new leaves with beautiful silvery, woolly, brown or white to fawn felt (at the underside of) the leaves. We call this 'indumentum'. See also the page 'Buds and leaves'.
