Named after Giovanni Zantedeschi, Zantedeschia is a genus in the Araceae family from Southern Africa, Angola and Malawi of 8 species of rhizomatous deciduous or evergreen perennial herbs to 2.5 meters. Most are summer growing, but there are two species from the Cape Province of South Africa that are winter growing. There are also many colorful hybrids.

A Zantedeschia identification guide and growing tips was published by Veld & Flora magazine, and is reproduced here.

The genus is monoecious with separate male and female flowers see Zantedeschia aethiopica.

Zantedeschia albomaculata is a summer rainfall species from eastern southern Africa found in marshy ground on rocky or grassy mountainsides. It is a medium/tall plant with arrow shaped leaves that often have white spots - the name means "spotted with white". It has white/creamy spathes, a few each year when young. It can be difficult to get a long enough growing season for flowering in cool climates. The first photo taken by Giorgio Pozzi June 2007 pictured below is a creamy spathe specimen growing in the wood with a hydrangea in background. Photos #2,3 were taken by Cameron McMaster. Photo #4 taken January 2010 by Bob Rutemoeller at Maclear.

Zantedeschia jucunda is a yellow flowered species with white spotted green leaves endemic to the summit of the Leolo Mountains in northeast South Africa. It grows in sunny, rocky, rather arid north and west facing hillsides. This species depends on good rainfall in late November for good flowering. Since it flowers better with good light, it benefits from fires and grazing by livestock which keep the cover short. Seed germination is erratic, but best after successive days of cloudy, rainy weather.

Zantedeschia odorata is endemic to the Bokkeveld Plateau where it grows in damp places in dolerite outcrops. It grows to 75 cm high and has arrow-like leaves. It can be distinguished from the other winter rainfall species, Zantedeschia aethiopica, by having a spathe that is scarcely flaring, a smaller spadix, and a fruiting peduncle that bends over. Flowers are very fragrant with a freesia like scent. Graham Duncan in Grow Bulbs comments that it "has very limited horticultural merit and is not more heavily scented than Zantedeschia aethiopica". This species is deciduous and flowers in habitat July-August. Photo taken in September 2011 near Nieuwoudtville by Cameron McMaster.

Zantedeschia pentlandii comes from the Mpumalanga and Limpopo provinces of South Africa where it grows in rocky places along mountain streams. The flowers are around 4 inches across and stand up to 29 inches tall. A common name is the 'Mapoch lily'.

Zantedeschia rehmannii or the pink Arum is a deciduous species found in grassland and on rocky hillsides in the summer rainfall areas (KwaZulu-Natal, Swaziland). Both its spotless leaves and its flowers are more slender than common hybrids. It blooms in summer. Photo by Mary Sue Ittner of a rhizome starting into growth (laid on a grid with 1 cm. squares). Pic 2 by Martin Bohnet shows the flower.

Atholl Selkirk (Gauteng, South Africa)

I am so excited. I have hundreds of seedlings of Zantdeschia odorata. The seed was from my own bulbs. They germinated so easily in June/July. Now about 2 cm high.

Michael Mace (San Jose, CA, USA)

Congratulations, Atholl! Did you have to do anything special to get them to germinate? Come back later and let us know how they turn out.

Z. odorata is a desirable species - PBS members would have liked some seed 8-) Some of my Z. aethiopica are scented. I am vaguely trying to select the trait.

G'day Guys - Do you know anywhere in Australia that I can access some of these more exotic callas? Odessa, Picasso, Golden chalice and the like? Thanks

David Pilling (Blackpool, England)

Steve - I'm sorry I have no idea - obvious from my location. You might try asking on the PBS list, there are some Australian members who may know.

Steve Demamiel (Albury, Australia)

Thanks David. I'll keep looking.

My Maltese Poodle chewed on a stalk of a "Zantedeschia 'Blaze'", which we have growing in our garden, and became violenltly ill.

Michael Mace (San Jose, CA)

Thanks for the note, Belinda. You're right -- according to Wikipedia, Zantedeschia contain a substance that causes an intense burning sensation in the mouth, and if eaten can cause serious symptoms. I hope your dog hasn't had any lingering effects.

We recently purchased our house in February when everything was dead, and now I'm finding little surprises all over the property! This was by far my favorite, because it started growing like a single blade of grass from an extra large pot we have out front, and just today (06/01/15) I noticed a bloom among the speckled leaves. By your helpful pictures, I would guess Blaze variety. If anyone could give tips on how to keep it alive, thriving, and returning every year, it would be greatly appreciated!
