Small shrub, 0.6–1.8 m. Leaves 4.5–10 × 1.8–5.5 cm, obovate to oblong, lower surface with a two-layered indumentum, the upper layer a fawn to red-brown densely matted tomentum, composed of dendroid hairs, the lower whitish, compacted; petioles densely tomentose or setose and tomentose. Flowers 4–8, in a tight truss; calyx 1–15 mm, when well-developed cupular, but with irregular lobes; corolla fleshy, scarlet to deep crimson, tubular-campanulate, with nectar pouches, 35–45(–50) mm; ovary densely rufous-tomentose, abruptly contracted into the glabrous style. Flowering March-June. Royal Horticultural Society (1997)

An evergreen shrub of close, dwarf habit as seen in cultivation but said by Forrest in a field note to be sometimes 6 to 10 ft high; young shoots clothed with a dense brown wool. Leaves leathery, obovate, abruptly contracted at the apex to a small mucro, tapered gradually to the base, 11⁄2 to 31⁄2 in. long, 3⁄4 to 11⁄2 in. wide, dark glossy green above, densely felted with reddish-brown wool beneath; stalk 1⁄4 to 1⁄2 in. long, woolly. Flowers in a terminal cluster of six to ten, on slender, downy stalks up to 11⁄2 in. long opening in mid-May. Calyx red, unequally five-lobed, up to 1⁄3 in. long. Corolla funnel-shaped with five broad, rounded, erect lobes; 11⁄2 to 2 in. long, nearly as much wide, scarlet to deep, rich, almost blood red. Stamens ten, 1⁄2 to 3⁄4 in. long, glabrous or nearly so; anthers brown. Ovary densely woolly; style glabrous. Bot. Mag., t. 9165. (s. Neriiflorum ss. Haematodes)

R. haematodes was discovered by the Abbé Delavay in the Tali range, Yunnan, where it is associated with R. neriiflorum at 12,000 to 13,000 ft. The cultivated plants descend mainly from seed-collections by Forrest in the same area in 1910 (F.6773) and 1917 (F.15521), both from low-growing plants, which may explain why this species is usually seen in gardens as a shrub only a few feet high and more in width. It is certainly one of the best of his introductions so far as this country in general is concerned, for it is very hardy. Its dwarf habit and slow growth make it suitable for the rock garden. It is the type species of a section of the Neriiflorum series distinguished mainly by the thick woolly covering on the young shoots and underneath the leaf. The richly coloured flowers are very effective and as a rule come late enough to escape frost. In the var. calycinum Franch., the coloured calyx is remarkably developed so that the lobes may be as much as 3⁄4 in. long.

R. haematodes received a First Class Certificate when shown by A. M. Williams, Werrington Park, Cornwall, on April 27, 1926.

Rhododendron haematodes (似血杜鹃) is a rhododendron species native to northeastern Myanmar, and southeastern Xizang and western Yunnan in China, where it grows at altitudes of 3,100–4,000 m (10,200–13,100 ft). It is a dwarf evergreen shrub that grows to 0.6–1.8 m (2.0–5.9 ft) in height, with leathery leaves that are oblong to obovate, 2.7–7.5 by 0.7–3.2 cm in size. The flowers are red.

The Latin specific epithet haematodes literally means "blood red", referring to the colour of the flowers.

In 1910 and 1917 the British botanist George Forrest collected seeds from specimens which may have been unusually dwarf in size, as they had previously been reported as growing much taller. It is very hardy and flowers in late Spring, thus avoiding late frosts. It is suitable for cultivation in a rock garden or similar.
