DescriptionHerbaceous or soft wooded shrub, 0.5 to 3 m. A very variable species, which may be armed on most parts, including the leaves, or may occasionally be unarmed. Stems and undersides of leaves may be densely covered in a whitish felt of stellate hairs, turning glabrescent with age. Leaves from lanceolate to broadly ovate; margin entire to deeply lobed with broadly triangular or rounded lobes; prickles on the midrib and lateal veins may or may not be present. Flowers in clusters along the branches, sometimes axillary or leaf-opposed; corolla pale to deep blue, mauve or purple, occasionally white, 1.5 cm in diameter, fragrant. Fruit spherical, green, often striped or mottled with white, turning yellow to orange-brown when ripe.
