Lonicera — 20 species

Lonicera, commonly called honeysuckle, is a genus of vigorous twining climbers and bushy shrubs prized for their tubular, often fragrant flowers. Most species thrive in full sun to partial shade and prefer consistently moist, well-drained soil, tolerating brief dry spells once established. Popular garden forms include Etruscan honeysuckle, Henry's honeysuckle, and box honeysuckle. All Lonicera species are toxic to cats and dogs — ingestion can cause vomiting, diarrhea, and lethargy — so keep them out of reach of pets.
