Convolvulus cneorum (more commonly known as Silver Bush) is an elegant plant that produces eye-catching silvery-grey foliage. An invaluable evergreen, the flowers bloom from pretty pink buds and open up into pure white cup-shaped flowers that have buttery yellow centres. These unique plants are a great addition to any garden that will create a distinct feature within patio containers or when planted at the front of garden borders. They prefer to be planted in sunny areas in well-drained soil, where they will flourish for years. Reaching a mature height of 60cm, this spectacular evergreen will flower from June through to September.
