A deciduous shrub of loose, spreading, scarcely climbing habit, thought by Rehder to be a hybrid between L. sempervirens and L. americana. It is a strikingly handsome honeysuckle, its leaves being oblong or oval, glabrous, scarcely stalked, 11⁄2 to 21⁄2 in. long, glaucous beneath. The uppermost pairs are united by their bases (connate). Flowers 11⁄2 in. long, rich pink outside, yellow within; produced in whorls on a rather long-stalked, terminal spike. Corolla-tube not downy outside, slender, slightly hairy inside. Blossoms from June onwards. This hybrid originated or was first noticed in the United States, but its history is unrecorded. It is quite hardy, and one of the best of its type of honeysuckle.
So far as is known there is only one clone of this hybrid. ‘Gold Flame’ is simply a commercial name for this, not a new cultivar of L. × heckrottii (Arnoldia, Vol. 22, p. 62).
