Shasta Viburnum Will Steal the Show With Its Stunning Flowers and Size
Shasta Viburnum shrub is sometimes called double file Viburnum because of the gorgeous double rows of flowers it produces. The flowers are lined up in flat rows on top of the green foliage to give a magical snow-like appearance!
The white flowers bloom in late spring and early summer and develop red berries throughout the summer. By fall, the berries turn black, and the foliage turns gorgeous shades of red and burgundy.
This Viburnum Plicatum tomentosum 'Shasta' shrub will be interesting to look at for the entire growing season. The flowers will attract butterflies, and the berries will attract birds, so it’s sure to breathe some life into your garden if you don’t already have it.
During the year, Viburnum plicatum Shasta will have green foliage that eventually fades into a plum purple color. The Shasta Viburnum fall color is so unique that this is one of the very reasons growers decide to add this evergreen shrub to their gardens.
Viburnum Shasta has so much going on that it can certainly stand alone and be the centerpiece of your property. It’s a tall and wide shrub, so it’s perfect for use around the foundation of your home or as a Shasta Viburnum hedge. If you use it on the border of flower beds, you may want to prune it often or leave enough space for this massive beauty to grow.
Shasta Viburnum Care
Shasta Viburnum double file grows the best in temperate climates. In the US, you’ll have the best results growing it in hardiness zones 5-8. It can tolerate heat and cold but will benefit from extra protection during the extreme temperatures summer and winter may bring.
Viburnum will grow well in full sun or partial shade. It may need afternoon shade if your summers have stretches of extreme temperatures, and it doesn’t grow well in hot climates that stay warm all year long.
Shasta doublefile Viburnum needs consistently moist soil, especially in hot summer temperatures. Water your double Viburnum regularly and avoid letting the soil dry out between waterings. Once the top of the soil looks dry, it’s time to water. If it frequently rains where you live, you may not have to water as often.
Even though Shasta Viburnum likes moist soil, it should be well-draining so excess water won’t create a puddle around the roots. The best soil to use is loam, but Viburnum can tolerate a variety of soils and won’t be too picky if you provide enough sunlight, water, and nutrients. You can amend poor soils with compost or slow-release fertilizer to create a better environment for your shrub.
Shasta Viburnum Size
This shrub usually reaches 6-8 feet in height and 9-12 feet wide. It grows a woody trunk, so while it is a shrub, it may be more like a tree in your yard. You can trim it as needed to keep the plant compact.
Shasta Viburnum Pruning
Viburnum is happy to grow freely, but you can prune it if you don’t want it to get large. Wait until the plant is finished flowering before you prune it, or you can do so in late winter before new growth develops.
If you want to keep the plant small and shrub-like rather than tree-like, expect to prune heavily every year since the plant will continue growing.
