Shasta and Mariesii viburnum are both large-flowered cultivars, but there are some notable differences between the two. Shasta, introduced in 1979, is a newer cultivar compared to Mariesii.
One key difference is in their growth habit. Shasta tends to be shorter and broader than Mariesii, which means it will become wider than tall as it matures. A mature Shasta plant can reach a height of 8-10 feet, while spreading out to a width of 10-12 feet. On the other hand, Mariesii may have a more upright and columnar growth habit, with a taller and narrower shape.
Another difference lies in their flowering and re-blooming behavior. While Mariesii viburnum is known for its ability to re-bloom, Shasta does not have this characteristic. This means that Mariesii may produce additional blooms after its initial flowering period, adding more visual interest to the plant throughout the growing season. Shasta, on the other hand, will typically only bloom once.
In terms of appearance, both cultivars have large flowers, but there may be subtle variations in their color and shape. It’s important to note that individual plants within each cultivar may also exhibit slight differences in flower color and shape, as well as overall growth habit.
When considering using either Shasta or Mariesii viburnum in your garden or landscape, it’s important to consider your specific needs and preferences. If you’re looking for a shorter, wider plant that does not re-bloom, Shasta may be the better choice. On the other hand, if you prefer a taller, narrower plant that has the potential to produce additional blooms, Mariesii might be a better fit.
While both Shasta and Mariesii viburnum are large-flowered cultivars, there are distinct differences in their growth habits, re-blooming behavior, and overall appearance. Considering these factors will help you choose the viburnum cultivar that best suits your gardening or landscaping needs.
