Cayenne
Cultivar · Cayenne Pepper, Cow-horn Pepper, De Cayenne, Guinea pepper, Guinea Spice

A classic hot pepper variety named after the capital of French Guiana, featuring long, slender, often wrinkled pods that taper to a point. Widely cultivated globally and essential in numerous cuisines, this productive plant yields thin-walled peppers that dry exceptionally well and are commonly ground into the ubiquitous cayenne powder found in kitchens worldwide.
History & lineage
Cayenne takes its name from the city and capital of French Guiana on the northeastern coast of South America - though the pepper's origins almost certainly predate European arrival. The Tupi people of the Amazon basin had cultivated similar long-pod chillies for centuries, and "Cayenne" became the European name for the type after French colonial trade routed the pepper through that port.
By the 17th century, dried and ground Cayenne powder was being shipped from French Guiana to Europe, where it became the standard "hot pepper" for several centuries - so much so that "cayenne" became a generic term for any ground hot chilli powder, much as "kleenex" became generic for tissue. Most cayenne powder sold today contains a blend of varieties, not necessarily the De Cayenne cultivar specifically.
The variety has been a workhorse of global cuisine for centuries. It's the heat in Louisiana hot sauces, the warmth in Indian curries before bird's-eye varieties dominated, and the basis of countless spice rubs and dry blends. Its thin walls and abundant flesh-to-water ratio make it ideal for drying - the property that earned it commercial dominance in the spice trade.
The name has since escaped the plant. "Cayenne pepper" on a supermarket shelf is a heat grade rather than a variety: most of what is sold under that name is a blend, often ground from whatever comparable chillies were cheapest that season, standardised for colour and pungency rather than grown as cayenne at all. It is one of the clearest cases in the whole subject of a cultivar name becoming a commodity description.
The plant itself is a family rather than a single thing — Long Slim, Ring of Fire, Joe's Long, Carolina Cayenne and dozens more, all sharing the same long, tapering, thin-walled pod. That shape is why it dominated the dried trade: thin walls give up their water quickly and evenly, so a cayenne dries on a string in a warm kitchen without any of the fuss a thick-walled pepper demands. Frank's RedHot, and with it most of what Americans mean by "hot sauce", is built on cayenne for the same reason — consistent heat, clean flavour, nothing complicated behind it.
Culinary uses
Dried and ground, mostly — cayenne is the standard hot chilli powder of half the world's spice racks, and it is worth grinding your own to see how much brighter it is than the jar. Thin walls make it the easiest chilli to dry at home: thread the pods on a string somewhere warm and they will keep for a year. Fresh, it slices into stir-fries and sauces without dominating, and its clean, straightforward heat is why it is the usual base for fermented hot sauce and infused oils. It is not a stuffing or roasting pepper: there is no flesh on it to speak of.
Growing it in the UK
Annuum is the forgiving group, and the right place to start. Seed germinates readily in warmth, the season is short enough to finish outdoors in a good summer, and February to early March is soon enough to sow. Germination is given as 10-21 days. At 70 days to maturity it is one of the quick ones: sown in March, it will be picking well before the light goes.
At 60–90 cm this is a substantial plant. Give it a 10-litre pot or a greenhouse border, and stake it before the fruit sets rather than after. The record puts the yield at heavy, so start feeding weekly with something high in potassium as soon as the first fruit sets — a plant carrying that much will run out of steam otherwise.
It is hot enough that gloves are sensible when you are preparing a batch, and that a seeded pod is a very different proposition from a whole one. Thin walls and a high drying score mean it dries well — thread the pods on a string somewhere warm and they will keep for a year.
