Serrano is a Capsicum annuum which is a species of the plant genus Capsicum native to southern North America, the Caribbean, and northern South America. This species is the most common and extensively cultivated of the five domesticated capsicums. The species encompasses a wide variety of shapes and sizes of peppers, both mild and hot, such as bell peppers, jalapeños, and cayenne peppers. Capsicum annuum is an evergreen Perennial growing to 1m by 1m at a medium rate. It is hardy to UK zone 9 and is frost tender. It is in leaf all year, in flower from July to September, and the seeds ripen from August to October. The species is hermaphrodite (which has both male and female organs).
Serranos have crisp, shiny fruits that measure 2.5cm-5cm long by 1cm across and mature from dark green to red. They have thick fleshy walls and so are best pickled or used fresh rather than dried and make great Salsas & Serrano chilli pepper sauce.
PLEASE NOTE - we do not recommend growing chillies on a windowsill, especially the hotter varieties. Chillies need a constant and consistent temperature to germinate and windowsills above radiators do not provide the ideal conditions.
