Species in this genus
The ones growers meet most — each links to its own page.
Zantedeschia aethiopica
Calla Lily
Zantedeschia aethiopica is a tuberous geophyte from seasonally moist grasslands and marsh margins of southern Africa, storing water in its tuber and resenting standing wet that rots it. Give bright indirect light and water when the top inch of mix has dried, then water thoroughly; let it approach dryness between drinks rather than staying soggy. It may slow or die back seasonally, which is natural for a geophyte and a cue to water more sparingly.
Zantedeschia rehmannii
Pink Arum
Zantedeschia rehmannii is a tuberous geophyte from summer-rainfall regions of southern Africa, storing water in its tuber and prone to rot if kept wet. Give it bright indirect light and let the top inch or two of mix approach dryness before watering deeply; through dormancy it wants far less water, often none. Use a free-draining mix and avoid standing water around the tuber.
Zantedeschia albomaculata
Spotted Arum
Zantedeschia albomaculata is a tuberous geophyte from KwaZulu-Natal, storing water in its tuber and prone to rot if kept soggy. Give it bright indirect light and a gritty, free-draining mix, and water only when the top inch or two of mix has dried. Expect a natural rest period when foliage dies back, during which it wants far less water.
About the genus
A genus-level overview — shared traits, history, the botany that ties these plants together — is on its way. For now, the species and cultivars above and below carry the genus.
Kept true by its growers
Zantedeschia keeps evolving — species move, cultivars appear, IDs get corrected. If you can place an unplaced plant or add a species we’re missing, the whole genus gets truer.
