2. The Broadwalk

The long avenue in front of you is the Broadwalk, one of the longest herbaceous borders and the Botanic Garden's 'spine'. From spring to autumn, it is a blaze of colour as geraniums, penstemons and salvias mix with day lilies and sneezeweeds. Later on, winter flowering shrubs mix with the coloured barks of maples, birches and dogwoods. A network of small paths, which thread through the Upper Broadwalk, allow you to get up close to all of these beautiful plants.
