A deciduous, semi-prostrate shrub 6 to 18 in. high, twice or thrice as wide, with round, slightly grooved, slender branches, hairy when young, afterwards glabrous. Leaves simple, linear, about 1⁄2 in. long, hairy. Flowers produced singly, in pairs, or in threes at each joint of the previous summer’s growth, deep golden yellow, forming charming sprays of blossom up to 1 ft in length. Bot. Mag., n.s., t. 366.
A chance hybrid raised at Kew in 1900, and first noticed in a bed of seedlings of C. ardoinii. The pollen parent was evidently C. purgans, which it resembles in leaf and stem; its semi-prostrate habit it inherits from C. ardoinii. It flowers in May, and is then one of the prettiest of dwarf brooms; it is, however, at its best when two or three years old.
