Golden Chain Tree Laburnum x watereriThere is probably no more beautiful sight in the garden than a golden chain tree in bloom with its long dense pendulous chain of yellow pea-like flowers in spring. As the season progresses the small tree puts out finely-textured blue-green foliage with most leaves on the upper part of the tree so that the lower portions tend to be leggy. Unfortunately, the golden chain tree disdains climates with heat and humidity and is hardy only to zone 5 but if you live in an area where it can grow it is a spectacular beauty for about 10 days in May. Grow it as a specimen, in a group, or trained over metal archway as the British writer and gardener Rosemary Verey did for her famous laburnum walk. The Golden Chain tree may have health issues and tends to be short-lived.
