Shasta Doublefile Viburnum

Shasta Doublefile Viburnum (Viburnum plicatum f. tomentosum 'Shasta')

Shasta Doublefile Viburnum brings strong structure and a bright spring bloom show to the landscape with a naturally layered look. Its wide, arching form fills space quickly, helping borders and property lines feel more private and finished. In late spring to early summer, the branches line up with crisp white flower clusters that read from across the yard. As the season progresses, it can add colorful fruit and fall foliage, giving you more than a one-season performance.

Distinctive Features

This deciduous viburnum is known for tiered, horizontal branching and flat lacecap flower clusters that create a classic doublefile effect along the stems. The blooms feature showy outer white florets surrounding a fertile center, and flowering is often abundant. Pleated, deep green leaves keep the shrub looking refined through summer, thenFwith fall color that can shift to burgundy and purple-red tones in good conditions. After bloom, fruit may develop, typically starting red and maturing to black, adding another layer of late-season interest and wildlife value.

Growing Conditions

• Water: Medium water, keeping soil evenly moist during establishment and watering deeply during extended dry periods.
• USDA Zones: Zones 5 to 8.
• Mature Size: About 6 to 8 feet tall and about 9 to 12 feet wide.
• Habit: Dense and spreading with distinctive layered, horizontal branching.
• Bloom Season: May to early summer.

Ideal Uses

Low Maintenance Care

• Watering: Water regularly the first growing season, then deep water during drought to reduce stress.
• Mulching: Mulch to conserve moisture and moderate soil temperature, keeping mulch pulled back from the stems.
• Feeding: Feed lightly in spring only if growth is weak, since average soils are usually sufficient.
