This is a bushy shrub growing 2M tall, flowering on one or two year old growth. Bright yellow flowers, about 4cm across, cover the bush and arrive before the leaves.
There are a range of Forsythia varieties available and Karl Sax is one of the very best. Flowering along with the shrub Rhododendrons, Forsythia are one of the earliest flowering shrubs. Robust, reliable, and always eye-catching, this is a popular plant in Karin’s Garden.
