Price: No Price
Availability: in stock

Large evergreen shrubs or small trees with smooth and peeling reddish bark. Smooth, very “rhododendron-looking” leaves which can be up to one foot in length. The widely bell-shaped, often fragrant flowers (mid- to late spring) are some of the largest and most spectacular in the genus. They are pure white to white blushed rose and up to three inches long by six inches across. A stunning ornamental plant with attractive bark and really amazing flowers. The parent of many excellent hybrids (yes hybrids can be pretty nice sometimes) including the ‘Loderi’ grex. Needs a protected site for best performance, quite vigorous if happy and can be grown in a container for many years in colder climates. Native to forests in the eastern Himalayas from 6,000 to 9,500 ft.
