Rhododendron japonicum / Rengetsutsuji レンゲツツジ

 
Rhododendron japonicum is a deciduous, tuft-forming shrub inhabiting hills or grasslands in the lower parts of the subalpine zone, branches spreading obliquely sideways and growing to 0.5-2.5m in height. Barks are grayish-brown. Leaves are of alternate phyllotaxis; some of the individual leaves get together on the branch tips. Their blades, 5-10cm in length, 0.5-3cm in width, are oblanceolate, the bases taper off towards 3-7mm long petioles; the texture is thin, and the margins are entire, wavy, and have bristles curving towards the inside. The hairs are sparsely on either side of leaf surfaces also. Flowers open as the leaves develop; branch tops bear 2-8 light orange-red flowers together - the corollas, each 5-8cm long, are funnel−shaped, cleft in 5, and upper segments have spots darker than around. Sepals cut in 5 as well, and the margins have long hairs. Bloom time. May-June.
