ON THIS PLANT

Laburnum alpinum, commonly known as the Alpine laburnum, is a deciduous shrub or small tree belonging to the Fabaceae family. Native to the mountainous regions of central and southern Europe, it can reach heights of up to 10 meters. The plant features a dense crown of bright green pinnate leaves, each with three leaflets. In late spring to early summer, Laburnum alpinum produces captivating clusters of bright yellow flowers that dangle from its branches. These highly fragrant flowers are particularly attractive to bees and other pollinators. The plant prefers well-drained soil in full sun or partial shade but can adapt to a wide range of soil types. Once established, it is relatively drought-tolerant. While Laburnum alpinum is a visually appealing ornamental plant, it is important to note that all parts of the plant are toxic if ingested. The seeds, in particular, contain cytisine—a potent alkaloid similar to nicotine—which can cause severe poisoning if consumed in large quantities. Overall, Laburnum alpinum makes an excellent addition to any garden due to its striking appearance during the flowering season, but it should be handled with care due to its toxic nature.
