Detailed Information

Flower: Flower shape: 5-petals Flower shape: tubular Cluster type: raceme

[photo of flowers] Clusters of 2 to 7 short-stalked flowers at the tips of 1-year-old branches and arising from leaf axils near the branch tips. Flowers are funnel-shaped, ½ to ¾ inch long, hairy on the inner surface especially inside the tube, and with 5 narrow, spreading lobes, one of which typically is somewhat larger and has a darker coloring than the rest. In the center are 5 densely hairy stamens with yellow tips and a long, slender, green style with a dome-shaped stigma at the tip.

[photo of reddish flowers] Flower color is initially pale yellow or even greenish yellow, becoming orange to red with age. The 5 sepals surrounding the base of the flower are narrowly triangular and about as long as the floral tube. The ovary sits between the stalk and flower.

Leaves and stems: Leaf attachment: opposite Leaf type: simple

[photo of leaves] Leaves are 2 to 5 inches long, 1 to 2¾ inches wide, lance-elliptic to egg-shaped with a rounded or tapered base, a long taper to the pointed tip, and a short stalk. Edges are finely toothed and finely hairy, surfaces are mostly hairless except sometimes along the midvein. The upper surface is dark green, the lower paler, and leaves may be tinged a bronzy color across the surface or around the edges, especially when young.

[photo of bud] Twigs are green or reddish brown, hairless or minutely hairy in lines. Older bark is brown to gray, becoming hairless. Plants sucker from spreading rhizomes, often forming colonies.

Fruit: Fruit type: capsule/pod

[photo of developing fruit] The persistent sepals spread out as fruit develops, capping the fruit forming below. Fruit is a 2-valved capsule 1/3 to ½ inch long, green to brown, oblong-elliptic to narrowly egg-shaped. Plants are self-sterile, requiring pollination from a different plant that is not a clone.

[photo of capsules in winter] The capsules persist through winter.

[photo of seeds] Seeds are less than .5mm long, golden brown with a textured surface.

Notes:

Formerly in the Caprifoliaceae (Honeysuckle) family, this species gets its “honeysuckle” common name and lonicera species epithet from the shape of its flowers, which resemble those of true honeysuckles (Lonicera species), but that's where the similarities end. Bush Honeysuckle has serrated leaves and the fruit is a capsule, where true honeysuckles have toothless leaves and berries for fruit.

There is nothing about the pink Honeysuckle in this site. If you find the yellow you normally find the pink.

The pink honeysuckles are European or Asian species that are sold in the nursery trade and escape cultivation.
