Calla (Bog Arum) is a genus of flowering plant in the family Araceae, containing the single species Calla palustris.

Zantedeschia is a genus of twenty-eight species of flowering plants in the family Araceae, native to southern Africa from South Africa north to Malawi. Common names include arum lily and calla lily, the latter confusing as it is also the scientific name of the related genus Calla.

The Heartsease (Viola tricolor) is a common European wild flower, growing as an annual or short-lived perennial. It has been introduced into North America, where it has spread widely, and is known as the Johnny Jump Up (though this name is also applied to similar species such as the Yellow Pansy). It is the progenitor of the cultivated Pansy, and is therefore sometimes called the Wild Pansy; before the cultivated Pansies were developed, "pansy" was an alternative name for the wild form.

Persimmon most commonly refers to the edible fruit borne by some species of the genus Diospyros. They are also known as kaki (D. kaki), sharon fruit (D. kaki, a trademark name, exclusively reserved for persimmons grown in Israel), black sapote, mabolo or velvet-apple, date-plum (D. lotus), Texas persimmon and American persimmon. The term is also used to refer to the trees bearing the fruit.
