Laburnum alpinum - Shrub - Scotch Laburnum Page

Laburnum alpinum (Scottish Laburnum), also known as Scotch Laburnum or Alpine Laburnum, is a stunning leguminous flowering tree native to the Alps and Eastern Europe. Despite its name, it is not native to Scotland. The tree boasts gorgeous yellow flowers that form in 15-inch pendulous clusters in May, creating a magnificent display against its deep green leaves. Few trees are as lovely in bloom as the Laburnum alpinum.

Laburnum alpinum is a small, short-trunked tree or can be grown as a large shrub. It is an easily grown and very tolerant plant, succeeding in almost any soil or situation as long as it's not waterlogged. The tree thrives in heavy clay soils and poor shallow limestone soils, making it versatile and adaptable. It can withstand cold exposed situations and even tolerates industrial pollution.

In terms of cultivation, Laburnum alpinum is an ornamental tree that can be transplanted successfully even when it's large. It prefers well-drained, light to medium soil but can also tolerate heavy clay and nutritionally poor soils. It can grow in semi-shade or full sun and can withstand strong winds. However, it is not suitable for maritime exposure. The tree is notably susceptible to honey fungus.

It's important to note that all parts of Laburnum alpinum are highly poisonous and should not be ingested or used internally. The seeds, in particular, are toxic if eaten.

Due to its ornamental value, Laburnum alpinum is often used as a small specimen tree or shrub around residential homes. It also works well in shrub borders or grouped together as a shrub to maximize the visual impact of its spring bloom. Furthermore, it serves as a good background plant in landscaping.
