Mountain ash is a common tree in our country that is hardy and resistant. Autumn Spire is a columnar variety with slim crown and dense growth. It is most valued for its autumn foliage and profuse flowering.
It bears deciduous, pinnate leaves composed of deep green leaflets, serrated at margins. They turn rich red and burgundy red in autumn. The flowers are creamy white, composed in corymbs, and come out in late spring. They are followed by golden yellow fruit which lasts long and birds eat them only when other red berries have been harvested..
Mountain ash will grow almost everywhere. It likes well-drained, preferably acid soil. Pruning should be limited to avoid fungi infections. Fully hardy to min. -34°C (USDA zone 4).
