Family Apocynaceae

'Storm Cloud' captivates with its almost black stems and silver-veined olive-green foliage, providing a dramatic contrast to the garden. In spring, it is covered in a cloud of starry, periwinkle-blue flowers, often continuing into early summer. Its broad, bushy habit resembles a small shrub, perfect as a mass plant or structural accent.
