Tabasco (C. frutescens)

According to Floridata, “C. frutescens and C. chinense are quite difficult to distinguish, and many authorities lump them as one species, C. frutescens, which is characterized by having two or more purple or greenish white flowers at each node. […] C. frutescens (including C. chinense) probably originated in the Amazon basin of South America.”

Wikipedia has the following to say: “the tabasco plant has a typical bushy growth […]. The tapered fruits, around 4 cm long, are initially pale yellowish-green and turn yellow and orange before ripening to bright red. Tabascos rate from 30,000 to 50,000 on the Scoville scale of heat levels, and are the only variety of chili pepper whose fruits are “juicy”; i.e., they are not dry on the inside. Unlike most chilis, tabasco fruits grow up, rather than hanging down from their stems.
