Plant description
Delivering dynamic seasonal drama from a remarkably compact footprint, this award-winning columnar tree transforms through the seasons with spectacular flair. Sorbus 'Autumn Spire' begins its annual display with clusters of pristine white flowers in late spring, followed by unusual yellow berries with distinctive red centres that prove irresistible to garden birds.
The real drama unfolds in autumn when its bright green pinnate foliage ignites into a breathtaking fusion of purple, red, and yellow tones, creating a striking contrast against the abundant fruit.
This Royal Horticultural Society Award of Garden Merit winner proves particularly valuable for smaller gardens or urban spaces, maintaining an elegant upright form while demonstrating impressive resilience to both city pollution and coastal conditions. While adaptable to most situations, this sophisticated Mountain Ash variety performs best in sites with good drainage.

How to care for Sorbus Autumn Spire ('Flanrock') (PBR):
Avoiding frozen and waterlogged soil, trees should be planted out as they arrive. If you've ordered a bare root tree, soak the roots in a bucket of water for half an hour prior to planting, or if this is not possible, they can be heeled in temporarily, covering their roots with soil, or potted up.
Protect from cold, drying winds. When planting incorporate lots of well-rotted garden compost in the planting hole. To safeguard your trees during shipping and their initial growth, we may supply them attached to a bamboo cane. This support system helps prevent bending or snapping during the early years, ensuring a strong and healthy start. We recommend leaving the cane in place for up to three years, checking the ties seasonally to prevent excessive tightening. Once the tree has developed sufficient strength to stand independently, the cane can be removed. In addition, we advise staking the tree and any attached cane, securely to provide additional support.
Requires minimal pruning. Remove any broken, diseased or crossing branches in late autumn or winter.
