Laburnum × watereri ‘Vossii’

Laburnum × watereri ‘Vossii’ Description

Laburnum × watereri ‘Vossii’ is a deciduous small tree famous for its long, pendulous clusters of bright golden-yellow pea-like flowers in late spring and early summer. The racemes can reach 40 to 50cm or more and are particularly effective when the tree is trained over a pergola or arch. Mature specimens generally reach around 5 to 7 metres high with a broad crown. Grow in full sun or partial shade in fertile, well-drained soil and avoid permanently wet ground. It is hardy and performs well in Irish gardens. Flowers are attractive to pollinating insects. All parts of laburnum contain toxic compounds, with the seeds posing a particular risk if swallowed, so this should be considered where young children or grazing animals have access.
