Prime White Convolvulus produces clean white funnel-shaped flowers on a compact, spreading mound of silvery-grey foliage. It has the same drought tolerance and easy character as the blue forms but in a cooler, more neutral colour that pairs well with almost any surrounding planting. Grows to around 20-30cm with a spreading habit. Full sun. Well-drained soil. Drought tolerant once established. Trim lightly after flowering.
