A deciduous shrub up to 4 to 6 ft high, with flowering twigs downy; barren young twigs less so, or glabrous. Leaves produced along the entire shoot, oblanceolate, tapered at the base and oftener rounded than tapered at the apex, 1 to 13⁄4 in. long, 1⁄3 to 1⁄2 in. wide; glabrous, pale green above, somewhat glaucous beneath. Flowers glistening white, fragrant, produced during May and June in terminal heads of usually four to twenty blossoms; the perianth 1⁄3 in. across, with ovate lobes; tube 1⁄3 in. long, cylindrical, silky outside; ovary slightly downy. Bot. Mag., t. 7388.
Native of the Caucasus; many times introduced and lost. It is not outstanding, but is pleasing in its fragrance and for its abundant flower-clusters borne at the end of crowded, short, leafy shoots springing from the previous year’s growth. It differs from D. alpina in its glabrous leaves.
