A very rare species in cultivation, this is closely related to the more familiar glischrum, differing in its shorter foliar and stem hairs giving it a “fuzzy” appearance. Pink to white flushed pink flowers, usually with red spots. Best in light shade. This offering has been grown from hand-pollinated seed produced here at the RSBG.
A fast-growing species with strong upright growth and very attractive, shiny foliage. The bell-shaped flowers (late spring to early summer) range in color from white to pink. Very closely related and similar to the more commonly grown aberconwayi which differs in having flatter, less bell-shaped flowers. Grown from seed collected in the wild. Somewhat drought tolerant once established.
A fast-growing species with strong upright growth and very attractive, incredibly shiny foliage. As the name suggests, these should have an inflorescence of hanging flowers ranging in color from white to pink, in late spring. The first re-introduction in the modern era. Grown from seed collected in the wild. Somewhat drought tolerant once established. Really great foliage on these young seedlings.
Large, upright evergreen shrubs with masses of beautiful flowers in mid-spring. Easily grown in sun or shade and very floriferous. Great with white and pink flowered rhododendrons. An RSBG selection. In my opinion, this is the finest form in our substantial collection of this species. The large flowers are as close to a true blue as you will see in augustinii. A real winner.
Large, upright evergreen shrubs with masses of beautiful flowers in mid-spring. This selection has large deep blue-purple flowers with a large greenish blotch and is one of the last forms of this variable species to flower in spring. Easily grown in sun or shade and very floriferous. Great with white and pink flowered rhododendrons. An outstanding selection.
A relatively newly described species. This is considered to be related to the rarely cultivated, though widespread species – R. micranthum and has similar flowers that are small and white in rounded clusters, much like a ledum. The very distinct glossy foliage is long and narrowly elliptic and densely brown scaly beneath. Quite rare in the wild, currently known only from a small area in eastern Guizhou, China.
Large upright shrubs with shiny foliage and pinkish to lavender or (rarely) white flowers in mid-spring. The leaves have a dense and dark indumentum beneath. Grown from seed produced by a hand-pollination of two of our best clones here at the RSBG. Native to the Himalaya Mountains where this is a common, widespread and variable species.
A newly introduced species and one of the most important introductions in the last twenty years. This species forms a rounded shrub with large and deep green, very rounded leaves – a stunning plant in foliage. In mid-spring the large flower buds expand to upright inflorescences of 18 (or so) funnel-shaped and pink, lightly fragrant flowers (similar to those of its close relative – R. fortunei) - quite remarkable. Grown from hand-pollinated seed produced here at the RSBG from the original introduction of this species from its type location in southern China. This taxon was long thought to be a subspecies of its relative R. orbiculare which also has rounded leaves, but which is found far to the northwest in Sichuan, and which has completely different flowers. I am hereby (unofficially) restating it as a separate species. Beautiful bluish cast to the new growth and a vigorous habit. Best in light shade and has been perfectly hardy outside here so far. You will love this.
Large upright-growing evergreen shrubs with superb pendulous flowers in late spring. These are tubular in shape and quite variable in color, ranging from red, plum-crimson, salmon-pink, pink, yellow-orange and apricot to various bicolor and even tricolor combinations. This selected clone from Warren Berg has large, glaucous red flowers and bright blue-green foliage.
