About plant names...

Cayenne peppers are natives of southern North America and northern South America. Most of the peppers we eat or grow as ornamentals are cultivated from this species, including anchos, banana peppers, cayennes, de árbols, guajillos, jalapeños, anaheims, Italian sweets, pasillas, peperoncinis, pimentos, poblanos, serranos, and tabascos. (A few, habaneros among them, have other origins.) 'Filius Blue' peppers, named for the blue color of the young fruits, are believed to have originated in Mexico.

If you are curious as to the origins of these popular peppers, consider Kraig Harris Kraft's 2009 dissertation on the subject, The domestication of the chile pepper, Capsicum annuum: Genetic, ecological, and anthropogenic patterns of genetic diversity.

Identification: Plants are up to 1½′ (45 cm) high, densely branched. They are annuals in cooler climates and woody perennials in warmer ones. (Woody variants are sometimes referred to as Capsicum frutescens, but there is little evidence to support this separate classification.) Leaves are oblong-ovate, ovate, or ovate-lanceolate, 1-2″ (2.5-5 cm) long. Flowers are purple, about 1″ (2.5 cm) in size, appearing from May to October. Fruits are shiny ovals, ½-¾″ (1.3-1.9 cm) around. They are purplish-blue when young, becoming red.
