They are deciduous shrubs growing to a height of 1 – 3 metres. The flowers are produced in the early spring before the leaves. The flowers become pendant in rainy weather to protect the reproductive parts. Here they have performed just as they should.
The genus is named after William Forsyth, a Scottish botanist who was royal head gardener and a founding member of the Royal Horticultural Society.
These lovely yellow flowers are a sure sign of spring.
