Viburnum Sargentii Onondaga

Viburnum Sargentii Onondaga, a recipient of the prestigious RHS Award of Garden Merit,  is a large, deciduous shrub. It is a cultivar of the species Viburnum Sargentii, which is native to Japan. ‘Onondaga’ is known for its beautiful foliage and showy flowers, which make it a popular ornamental plant in gardens and landscapes.

The shrub can reach a height and width of up to 2.5 metres, and it typically grows in a rounded shape. Its leaves are large, oval-shaped, and dark green, with a slightly serrated margin. In the Autumn, the foliage turns a deep red-purple, providing a spectacular show of autumn colour.

The flowers are another notable feature of the plant. They appear in early Summer, and are large, flat-topped clusters of pinkish-red flowers, which are followed by bright red fruit in the Autumn. The fruit is edible but not particularly tasty, and is usually left for the birds to enjoy.

It prefers a well-drained soil, and can tolerate a range of soil types, from acidic to alkaline. It grows best in full sun to partial shade, but can also tolerate deep shade. It is a relatively low-maintenance shrub, and is generally disease and pest-resistant.

Overall, this is a versatile and beautiful shrub that adds interest and colour to any garden or landscape. Its showy flowers and attractive foliage, along with its ease of care, make it a popular choice among gardeners and landscapers alike.

• Soil and Sun Requirements: Prefers well-drained soil that is moist, but not waterlogged. It grows best in full sun to partial shade, but can also tolerate deep shade.
• Watering: Once established, it is relatively drought-tolerant, but it’s important to keep the soil consistently moist during the first year after planting. Water deeply and regularly during the first growing season to help the plant establish a strong root system.
• Fertilisation: Doesn’t require a lot of fertiliser, but you can give it a boost in the Spring with a slow-release, balanced fertiliser.
• Pruning: Doesn’t require extensive pruning, but you can shape it to your desired size and shape in early Spring. You can also remove any dead, damaged or diseased branches.
• Mulching: Apply a layer of organic mulch around the base of the plant in the Spring and Autumn to help retain moisture, suppress weeds, and improve soil quality.
• Winter Care: It is hardy, but it can benefit from Winter protection in colder climates. You can cover the plant with a frost blanket to help protect it from extreme cold and wind.

By following these guidelines, you can keep your Viburnum Sargentii Onondaga healthy and thriving for many years to come.
