Sargent's Viburnum 'Onondaga'

Sargent’s Viburnum ‘Onondaga’ (Viburnum sargentii ‘Onondaga’). Viburnum sargentii ‘Onondaga’, commonly known as Sargent’s viburnum ‘Onondaga’, is a deciduous shrub with an upright, bushy habit, prized for its spectacular foliage and contrasting blooms. In spring, its young leaves emerge bronze-purple before turning dark green, creating a rich backdrop for its large, flat inflorescences composed of small, burgundy-red fertile flowers surrounded by pinkish-white sterile flowers. This spring bloom effectively attracts pollinators. Later in the season, it produces clusters of decorative bright red berries, enjoyed by birds.

To plant Sargent’s viburnum ‘Onondaga’, choose a suitable exposure: sun to partial shade. The recommended soil is well-drained, tolerant of ordinary and slightly clayey soil. Water the root ball before planting it 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 crown clear. Avoid systematic fertilizer applications without considering the soil's richness. In Quebec, choose a period when the soil is thawed and easy to work with.

Allow for a width of 2.5 m (8 ft) when planning this plant's space in the garden. The indicated height of 3 m (10 ft) helps choose its position relative to neighboring plants. Maintain access to the base for weeding, checking moisture, and removing damaged parts. Combine this variety with plants that have compatible light and water needs. 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.
