Editorial Note
Bean treated this species as a variety of Daphne kamtschatica, but Clarke in the Supplement (1988) supplied a separate species entry for D. jezoensis. The text below adapts and combines the two entries to reflect the updated taxonomy.
A stoutly branched, glabrous, summer-deciduous shrub. Leaves produced in autumn and shed the following summer, up to 3 in. long and 11⁄4 in. wide, oblanceolate with a cuneate base, almost sessile, glossy above. Flowers pale to deep yellow in mostly terminal clusters; tube funnel-shaped; lobes ovate, about 1⁄4 in. long, on cultivated plants opening in November and December, sometimes later, but on wild plants in early to late spring. Fruits red. Bot. Mag., n.s., t.613.
A native of northern Japan in subalpine woodland; discovered and named by Maximowicz, but first described by Regel in 1866 from a cultivated plant; introduced to Britain by H. Money-Coutts, who distributed seedlings raised from seeds collected in northern Honshu. Both its foliage and flowers are moderately frost-resistant, and the plant itself is hardy. Unlike most daphnes, it is intolerant of chalky soils.
For further details see Brickell and Mathew, op. cit., pp. 119–22 and the latter’s article accompanying the plate in the Botanical Magazine.
This species differs from D. kamtschatica (which is probably not in cultivation) in its narrower leaves and smaller flowers, and from D. pseudomezereum in its obovate-oblong leaves, rounded at the apex, and its yellow, fragrant flowers. It was in flower in the Alpine House at the R.H.S. Garden, Wisley, in March 1968.
