Osteospermum 'Iced Gem'

African daisy 'Iced Gem'

An upright and gently spreading shrubby perennial that thrives in sun and grows up to approximately 30-40 cm high. The leaves are quite striking: grey- to mid-green with pale creamy yellow variegation, up to 10cm long, and can be linear or lance-shaped, and can have toothed edges. The daisy flowerheads are about 5-8cm across, with bright silvery-white petals which are touched with blue-purple at their bases as they approach the blue-purple flower centres.
