Buddleja Butterfly Towers This variety of buddleja is in fact a world exclusive... straight from our breeding programme! This unusual, upright Buddleja has a tall, columnar habit, which produces an exquisite tower of beautiful mauve-purple flowers. Each large, upward-pointing bloom offers a valuable source of nectar that will be a magnet for bees and butterflies through the summer period. This slender hardy shrub is super reliable and easy to grow. It is undemanding, unlike traditional varieties, making it a brilliant hedging plant for growing colourful garden screens. Height: 2m (6\'). Spread: 1m (3\').
