One of the most popular spring flowering trees. Laburnum Vossii is a particularly free flowering Laburnum with exceptionally long fragrant racemes of bright yellow flowers that trail down up to 50cm. A small vase shaped tree that rarely grows taller than 5 metres, it can also be trained onto arches and other shapes. A very tolerant and easy to grow tree needing little more than reasonable drainage. All parts of Laburnum are poisonous to humans.
