Now here?s something a little different for your garden! Sollya heterophylla is better known as the Bluebell Creeper. Its twining stems are cloaked in evergreen foliage that makes a splendid backdrop for its nodding, sky blue flowers throughout summer. This half-hardy climber is perfect for growing in the conservatory, and will even thrive outdoors in the mildest parts of the UK. Alternatively, grow it in patio containers that can be moved into a heated greenhouse during the winter months. . Height: 2m (6', 6). Spread: 60cm (24).
