knotweed 'Silver Dragon'

A fast-growing, deciduous, herbaceous perennial, producing a mound of stems to 60cm (24in) high and 90cm (36in) across. The foliage is highly ornamental and is heart shaped, with a pale silver 'V' mark over a grey green base colour. Inside the 'V', the colour is pale purple-bronze with a darker bronze margin to the leaf. It is a useful plant to grow where rabbits and deer are a problem as they leave it untouched
