Description
This large, robust and vigorous ornamental tree has deep crimson/purple foliage throughout the spring and summer, hence the common name Purple Norway Maple. The autumn colour foliage ranges from orange to brown making this a spectacular Maple tree throughout most of the year. Flowers are small, yellow and tinted red in spring.
It will do well in most soils and is tolerant of many difficult conditions including exposed, coastal positions or chalky soil. Ideal for screening in larger gardens with an attractive rounded head in habit. Expect a height and spread of 8 x 5 metres in 20 years but more in maturity.

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
Trees and shrubs 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.
