This is a very fast growing and extremely hardy shrub. It has fine, dark green needle like foliage. Plant it against a west wall where it can enjoy abundant sunshine and give you a super display of colour in return. It produces masses of small yellow honey scented flowers from July to September. It thrives in a sunny position. Prune back after flowering to keep it neat otherwise it will become very untidy. The flowers attract butterflies. It is used medicinally as a treatment for cold and flu.
