Oscularia deltoides is a low-growing, succulent shrub with wiry, decumbent or trailing, grey-green, often purple-tinged stems and blue-green, 3-angled leaves with small, often reddish teeth. It can grow up to 1 foot (30 cm) tall. The leaves are thick and fleshy, measuring up to 0.7 inches (1.8 cm) long and 0.4 inches (1 cm) wide.
The almond-scented flowers, which range from lavender-pink to purple with a yellow center, appear in spring and summer and can reach up to 0.8 inches (2 cm) in diameter. They are closed in the morning but open in the afternoon, often covering the plant.
