Deliciously honey-scented, Lonicera periclymenum 'Serotina' (Late Dutch Honeysuckle) is a compact, slow-growing, twining deciduous vine with large, 2 in. long (4 cm), tubular, crimson-budded flowers that open to reveal creamy-yellow throats. Produced in succession from late spring to the first frosts, the fragrant flowers eventually give way to translucent red berries.
