Florist’s cineraria, also known as common ragweed, has a fascinating past. The name cineraria is commonly used for the genus Pericallis x hybrida, a hybrid of two species, but that’s a bit of a misnomer. Developed in 1777 by the British Royal Gardens, florist’s cineraria was originally grouped under the species cineraria. Today, however, it stands alone under its own species name and includes plenty of varieties to choose from. Popular varieties include cineraria pink, cineraria purple, dwarf cineraria, cineraria jester, and the gorgeous, frosty-looking leaved silver dust.
