Description
Sorbus scalaris is an unusual variety of Rowan with delicate looking, frond-like foliage that is green in summer and turns orange, red and purple in the autumn. The shape of this attractive foliage has led to this variety being referred to as Ladder Rowan.
Tiny white flowers are held in bunches (corymbs) in May-June and are a favourite of bees during the summer months. Along with autumnal foliage colours, autumn also brings bunches of small orange/red berries that are popular with birds.
This tough Chinese Mountain Ash tree will grow in most soils and conditions including exposed positions. Slightly spreading in form and growing to just 5 x 4 metres, Sorbus scalaris is ideal for small spaces. It works hard for its position in the garden, providing changing seasonal interest and food for wildlife.

Planting Steps
1Preparation
- Pot-grown plants can be planted at any time of year, whereas bare roots need to be planted between November and March.
- Clear weeds and grass within a metre of the planting hole.
- Dig a hole as deep as the root mass and twice as wide.
- To help your plant establish more effectively, sprinkle Rootgrow in the hole.
2Planting
- Gently loosen the roots and place into the planting hole.
- Ensure the top of the plant’s compost is flush with the level of the surrounding soil and the graft union or collar of the tree is above ground level.
- Mix 50% of the original soil with 50% compost.
- Fill in the hole, firming the soil gently.
3Last Steps
- Water generously around the base of the plant.
- If you are planting either a single stem tree or mature standard tree, we recommend adding a staking kit and rabbit guard.
Aftercare Advice
Rowan require a good watering regime for a couple of years whilst they establish. Water well and regularly through spring and summer, increasing in hot or dry weather. If planting in autumn, you may only need to water a little. It is advisable to keep the area free of competing weeds and grass during this period.
Rowan trees require a strong framework to support their many berries, so it is good to encourage this by raising the crown in summer. Simply prune the lower branches and any crossing, damaged or diseased branches within the crown. Hard pruning can be carried out in the dormant season, from autumn to winter.
