Zantedeschia species are rhizomatous herbaceous perennial plants with some species (Zantedeschia aethiopica) growing to 1.2m tall, while Zantedeschia rehmannii does not exceed 60 cm in height, growing in clumps or clusters. Petioles are long, spongy in nature, sheathed at the base and of varying length from 15 cm (Zantedeschia rehmannii) to 1.5 m (Zantedeschia aethiopica) in length. The lamina is simple, elongated and coriaceous with a variety of shapes, including triangular, oval (ovate) with or without a point (elliptic), heart (cordate), spear (hastate), lance (lanceolate), oblong, or circular (orbicular). 15–60 cm in length, 5–25 cm in width. The leaves are dark green in colour and feather-veined (pinnate), and may be erect or spreading with undulate margins. Some species exhibit transparent flecking (maculation), and are therefore referred to as maculate, while others are immaculate.
