Native of the eastern and southern United States, reaching as far north as Connecticut and westwards to Texas; introduced in 1656. This beautiful honeysuckle thrives best in the milder parts but is hardier than was once supposed and should succeed with the protection of a wall over much of the British Isles. It received an Award of Merit in 1964.
