Viburnum — 15 species

Viburnum is a large genus of flowering shrubs and small trees — including guelder rose, snowball bush, doublefile viburnum, and wayfaring tree — valued for their showy flower heads, autumn berries, and reliable seasonal interest. Most species thrive in full sun to partial shade and prefer consistently moist, well-drained soil, though established plants show good drought tolerance. They suit borders, hedging, and wildlife gardens. Toxicity varies across the genus: some species such as Viburnum opulus carry mildly toxic compounds in their berries, while others are generally regarded as safe, so check each species before planting in pet-accessible areas.
