Dimorphotheca ecklonis is a perennial with a woody base. It may grow erect to 1 m tall or decumbent to 1 m wide. Flowerheads grow on short stalks at branch ends. They may appear solitary or in small groups. The ray florets are white on the upper surfaces, light blue or violet below. Disc florets, the centre of the daisy, are dark blue or purple.
The leaves are variable. They are fresh green, sometimes shiny, thinly fleshy, usually crowded near branch tips with bare lower stems. The leaf shape is elliptic, the margins entire to markedly dentate. Leaves are sessile, tapering to the base. The arrangement on the stem is alternate or sub-opposite (www.plantzafrica.com).
