In its native range Exacum affine is an annual or short-lived perennial and is suitable for permanent outdoor cultivation only in humid tropical and subtropical areas. Grown as a pot plant, this plant requires a well-drained, but moist potting mix. Exacum will tolerate good light but not direct sun.
Geraniums in the flowering genus Pelargonium are tender perennials, meaning they can be grown as perennials in areas where the temperatures do not drop below freezing and as annuals in colder climates. If you live in U.S. Department of Agriculture plant hardiness zone 10b, you can grow them outdoors all year round.
