The white candytuft flower is compatible with a range of tall, blooming annuals and perennials and is the perfect height to cover tall, bloomless stems of flowers such as zinnia, cosmos and evening primrose. Candytuft flowers are handy to cover up declining foliage of early spring blooming bulbs.
The plants are 40 cm (16 inches) tall and have long, narrow leaves. Rocket candytuft (I. amara) has thick, deeply lobed leaves and large white, often pink-tinged, fragrant flowers on 22-cm (9-inch) stalks. It grows on chalky hills and in fields. The evergreen candytuft (I. sempervirens) is a matting perennial with white flowers and is widely planted in gardens.
