Botanical nameSorbus sitchensis

Sorbus sitchensis, commonly known as Sitka mountain-ash, is an elegant and robust ornamental tree distinguished by its finely cut foliage and clusters of decorative berries. Highly hardy, it adapts well to cool climates like those in Quebec, finding its place in medium to large gardens where it provides seasonal visual interest and biodiversity. In spring, it is covered with delicate white inflorescences, followed in summer and autumn by ovoid fruits that attract birds, adding a rich and changing color palette. Its naturally rounded and well-proportioned shape makes it a popular option as a specimen tree, at the back of a border, or as a light informal hedge, combining structure, fine texture, and ecological attractiveness with minimal maintenance.
