Himalayan Honeysuckle is a deciduous shrub and was originally introduced, in the Victorian era, from China and Tibet as a shrub and planted as cover for pheasants.

The plant blooms from July to September. It produces berries in the autumn which are red at first, becoming black and subsequently eaten by birds.
