Description
Laburnocytisus ‘Adamii’ is a unique hybrid between Laburnum and Purple Broom. This small tree display a variety of fragrant, pea-like, yellow flowers (Laburnum), purple flowers (Purple Broom) and sometimes a mixture of both, resulting in attractive, coppery pink flowers, all appearing in spring. The foliage is mostly Laburnum-like (dark-green in spring and summer) but you may also find clusters of broom-like shoots.
Laburnocytisus Adamii has an unusual origin – at the Adam nurseries near Paris in 1825, a nurseryman was grafting Purple Broom after Laburnum and the accidental grafting resulted in this remarkable tree. Quite rare but easy to keep, Laburnocytisis is a stunning addition to any garden and is suited to a sheltered position with moist, well-drained soil in full sun. Broom Laburnum will grow to an eventual height and spread of 4 x 2.5m in 20 years. This unusual tree is a real conversation starter and will ensure you have the most original garden on the street!
Note: every part of this tree is toxic to humans and animals when ingested, especially the seed pods.

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.
