Sorbus Aucuparia Autumn Spire Mountain Ash

Sorbus Autumn Spire, commonly known as Mountain Ash Autumn Spire, is a compact, columnar deciduous tree with an elegant upright habit and outstanding seasonal interest. Sorbus Aucuparia Autumn Spire combines early-spring clusters of creamy-white flowers with summer foliage and abundant autumn berries, while its autumn leaf colour brings a dramatic late-season display. This Mountain Ash Autumn Spire is recognised with the RHS Award of Garden Merit and is recommended for pollinators. 
Synonym: Sorbus Aucuparia Autumn Spire.

In spring, Sorbus Autumn Spire produces dense clusters of honey-scented white flowers that attract bees and other pollinators. The fresh green foliage remains neat through summer before turning shades of orange, red and purple in autumn. Sorbus Aucuparia Autumn Spire follows the blossom with masses of small yellow-orange berries that persist into winter, offering an important food source for birds.

The narrow, formal silhouette of Sorbus Autumn Spire makes it an excellent choice where space is limited but seasonal interest is required. Mountain Ash Autumn Spire is particularly suited to small town gardens, courtyards and street planting where a vertical accent is desired without an overly broad canopy.

Compared with other Sorbus Aucuparia cultivars, Sorbus Autumn Spire stands out for its strongly columnar habit. Sorbus Aucuparia Fastigiata also has a narrow form but typically bears red berries and can have a slightly denser crown. By contrast, Sorbus Aucuparia Edulis has larger fruits and a broader natural crown. Sorbus Autumn Spire balances compact, upright growth with reliable ornamental berries and exceptional autumn colour, making Sorbus Autumn Spire a space-efficient and decorative alternative to the broader varieties.

Care Tips for Sorbus Autumn Spire

• Plant in fertile, moisture-retentive but well-drained soil; avoid waterlogged sites.
• Site in full sun or light shade for the best autumn colour and berry production.
• Minimal pruning required—remove dead, diseased or crossing branches in late winter.
• Apply a mulch annually to conserve moisture and suppress weeds; water during prolonged dry spells until established.
• Generally low-maintenance and disease resistant, though monitor for common pests such as aphids or fireblight in susceptible seasons.
