Scotch laburnum

Laburnum alpinum

Scotch laburnum is a deciduous shrub or small tree native to mountainous regions of Europe. Its bark is gray and smooth, with prominent lenticels. The dark green compound leaves are made up of 12-20 leaflets. In early spring, the tree is covered with fragrant, golden yellow, pea-like blooms. These are followed by long, hanging, velvety pods containing poisonous seeds. The tree has a habit of forming a thicket of stems which creates an interesting and dense landscape feature in the garden. A hardy and adaptable species, Scotch laburnum tolerates a range of soils and temperatures. It can be found thriving in sun or light shade.

watering

Scotch laburnum requires regular watering. During spring and summer, water regularly to keep the soil moist, but not soggy. In fall, reduce the amount of water so that the soil is allowed to dry out between waterings. In the winter, water sparingly, only when the soil begins to dry out. If there are periods of drought, be sure to water the plant more often.

sunlight

Scotch laburnum plants require full sunlight, receiving 6 to 8 hours of direct sunlight each day. For optimal growth, it is best to position the plant in an area that receives direct sunlight in the morning and then warm, indirect sunlight in the afternoon. If the plant does not receive enough sunlight it will become spindly and have unattractive blooms. It is important to make sure during the summer months the plant receives enough water, as it will become stressed if it does not get enough.

pruning

Scotch laburnum, also known as Laburnum alpinum, should be pruned twice a year: in the early spring and again in midsummer. In the early spring, prune all dead and any damaged branches. In midsummer, prune shoots that have grown more than 2 feet since the previous pruning. This helps to maintain the size and shape of the tree. Also remove any branches that cross over each other, as these can cause damage to the bark. Avoid pruning excessively, as this may have an adverse effect on the health of the plant.
