Hardy Chili Pepper

Juicy and berry-like with a candy-like sweetness and subtle tropical or vanilla-like undertones; the mild heat builds slowly and varies by fruit and growing conditions.

Capsicum flexuosum, sold under names like Hardy Chili Pepper and February Fire, is a wild member of the nightshade family native to the seasonally dry tropical biome of southern and southeastern Brazil, with extensions into northeastern Argentina and Paraguay. The plant grows as a deciduous shrub or small tree reaching up to 3 m (10 ft) tall and can live for decades. It bears attractive flowers, often white with green markings, and heavy crops of tiny (approx. 1 cm), bullet-shaped, fleshy berries that ripen red or occasionally orange and contain distinctive black seeds. The fruits have a sweet, tangy, tropical flavor profile with mild but variable pungency. Unusually for the genus, it exhibits strong cold tolerance, surviving prolonged exposure to temperatures around -15 °C (5 °F) and resprouting from the base after dieback in colder zones. Germination is slow and unpredictable, but once established the plants are productive and self-infertile (requiring multiple individuals for best fruit set). It holds value in scientific research as a phylogenetic bridge species.

Described scientifically in 1846 by Sendtner from Brazilian collections, Capsicum flexuosum has long been known locally as a wild spice plant but entered specialty horticulture more recently through dedicated seed producers. Its cold hardiness and genetic compatibility traits have made it of interest to breeders and researchers studying Capsicum evolution and interspecific hybridization. Today it is maintained in cultivation primarily by enthusiasts and small-scale seed companies preserving biodiversity.
