Description
The deepest colour of all the flowering Magnolia trees, Magnolia x soulangeana ‘Black Tulip’ brings a sense of drama to your planting space. The cup-shaped, deep pink, almost burgundy flowers emerge in early spring and are followed by the glossy green, large oval leaves. The first flowering may not be true to the size and colour, but as it matures this stunning Magnolia will produce deep pink, goblet-like flowers of up to 15cm in diameter. For a truly beautiful feature, plant Magnolia ‘Black Tulip’ in a spring garden for the ultimate specimen tree.
Compared to looser Magnolia varieties, ‘Black Tulip’ benefits from being more wind tolerant, although it’s still best to choose a sheltered site. Plant in a moist but well-drained site in full sun to partial shade. This deep pink Magnolia tree has a final height and spread of 6 x 3m with a full, rounded crown.

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
Magnolia 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.
Magnolia trees and shrubs can be pruned into shape by removing branches that are growing in an awkward position, as well as any that are damaged. They should not be heavily pruned as this can send them into shock. If pruning to limit the overall size, stagger your pruning over a few years to alleviate the stress on your tree. Pruning for Magnolia should be carried out in mid-summer to early autumn. Avoid pruning in late winter to early spring.
