Zantedeschia, a genus of herbaceous flowering plants in the family Araceae, native to southern Africa
It has often been used in paintings, and is visible in many of Diego Rivera's works of art (see The Flower Vendor, amongst others).
In common with similar livestock, others include: acorns, African rue, agave, amaryllis, autumn crocus, bear grass, broom snakeweed, buckwheat, ragweed, buttercups, calla lily, orange tree foliage, carnations, castor beans, and many others.
Several years later, additional purchases included amaryllis, cacti, succulent Euphorbia, Pelargonium, and Zantedeschia.
