?? Historical Background:

Cayenne peppers have a long history in Central and South America as a staple hot spice, prized for their pungency and culinary versatility. The name “Cayenne” is derived from the city of Cayenne in French Guiana. This particular variety has been embraced by European growers for greenhouse cultivation due to its adaptability to cooler climates and controlled growing environments like those common in Ireland.
? Gardener’s Tip:

Keep temperatures stable in your greenhouse and ensure good air circulation to reduce disease risk. Regular harvesting encourages continuous production and intensifies fruit heat.
