About this product

Sorbus aucuparia Joseph Rock is a stunning variety of Mountain Ash derived from the Chinese species. 

It has a pretty, delicate appearance. In 1950, it won the First Class Certificate and the Award of Merit.

This Mountain Ash has foliage similar to the species, with small, narrow, dark green compound leaves that turn flame red in the autumn. 

The creamy-white flowers appear in clusters around May or June. They are followed by interestingly creamy yellow berries hanging from the tree in clusters. The berries' colour contrasts fantastically with the bright red autumn colour.

As a juvenile tree, Sorbus aucuparia Joseph Rock has stiffly ascending branches. It forms a small, rounded tree at maturity and tolerates most soil types. 

A word of caution: this tree can be susceptible to fire blight. It is best avoided in areas where fire blight is common or present in nearby hedgerows.

This Mountain Ash is a perfect selection for gardens where its delightful show of colour will provide interest all year round. 

The creamy yellow berries do not look too tempting to birds, which often means this display of colour lasts well into the winter and can provide a beautiful picture in sharp frosts.

If you live in an area prone to rabbits or deer, we recommend rabbit guards for these trees.

Mature Height: 3-7m
