Arrowwood Viburnum

Arrowwood Viburnum (Viburnum dentatum). The Viburnum dentatum, commonly known as arrowwood viburnum, is a native deciduous shrub with an upright, bushy habit, appreciated for its hardiness and high ecological value. Vigorous and adaptable, it forms a dense mass ideal for informal hedges, natural screens, and biodiversity-friendly landscapes. In spring, it produces large, flat cymes of small, slightly fragrant, creamy white flowers, rich in nectar and highly attractive to pollinators. Its dull green, finely toothed foliage turns yellow to reddish-purple in the fall.

To plant arrowwood viburnum, choose an appropriate exposure: full sun to partial shade. The recommended soil is ordinary to slightly moist, well-drained. Water the root ball before planting and ensure that water can drain after planting. During establishment, check the moisture by hand before watering again. Spread mulch around the base, leaving the root collar clear. Avoid systematic fertilizer applications without considering soil richness. In Quebec, choose a period when the ground is thawed and easy to work with.

Allow for a width of 3 m (10 ft) to plan the placement of this plant in the garden. The indicated height of 3 m (10 ft) helps choose its position relative to neighboring plants. Keep access to the base for weeding, checking moisture, and removing damaged parts. Combine this variety with plants whose light and water needs are compatible. If you are considering a container, first check that its volume and drainage are suitable for root development. Roots in pots are more exposed to cold than those planted in the ground.
