The Woodbine (Lonicera periclymenum) has separate, opposite leaves, and buff-colored or paler yellow and red blossoms. There is a variety, the common monthly Woodbine, which produces its flowers all summer, and is much the most valuable plant. Another (L. p. belgicum), the Dutch Honeysuckle, blossoms quite early in spring: and a third (L. p. quercifolium) has leaves shaped like those of the oak tree.
