Description
Hamamelis x intermedia ‘Arnold Promise’ has sunflower yellow flowers from January – February, providing vibrant winter interest. Forming a much denser shrub than other Hamamelis, it produces a thicket of yellow/orange flowers that release a sweet perfume into the cold winter air. After the flowers, large green leaves open that turn attractive shades of yellow and orange in the autumn.
This award-winning yellow Witch Hazel shrub has a spreading, vase shaped form that provides beautiful architectural interest and will grow to 4 x 4 metres in 20 year. ‘Arnold Promise’ requires a well drained, acid – neutral soil in sun or partial shade and can tolerate some exposure. In addition, this winter flowering shrub provides important value to 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
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.
