Pyrus 'Chanticleer'Pyrus calleryana 'Chanticleer' is the perfect tree to wow your guests in autumn with its vibrant colours. During the summer, the leaves are a glossy dark green and as autumn approaches they turn to fiery red, purple and scarlet, putting on a spectacular show. In spring, your Ornamental Pear tree also delights the eye with a mass of single white flowers that last through April and May. Set against the luscious green foliage, they look quite stunning.
