Noteworthy Characteristics

Zantedeschia rehmannii, commonly called pink arum or simply calla lily, is a stemless herbaceous perennial of the arum family whose flowers and leaves rise to 1.5’ tall from underground tuberous rhizomes. Native to the grasslands and rocky hillsides of eastern South Africa and Swaziland in areas that receive summer rainfall. This species is distinguished from other calla lilies by its spotless, lance-shaped leaves, magenta to pink flower color, and smaller stature. The flowers can reach up to 3" in diameter, and often have a creamy blush at the edge of the spathe. The inner spadix is yellow.

Genus name honors Giovanni Zantedeschi (1773-1846), Italian botanist.

The specific epithet rehmannii honors Anton Rehmann (1840-1917), a Polish geographer and botanist who traveled extensively through South Africa on plant collecting trips.


Susceptible to rhizome rot. Japanese beetles may feed on the flowers/foliage.
