Jalapeno chilli seeds are a classic choice for anyone who enjoys traditional Mexican or Tex-Mex cuisine. These extremely popular thick-walled chillies carry a medium heat and a distinctive fresh pepper flavour. While they are typically harvested when green, leaving them to ripen to red will give them a sweeter, more complex taste. They can also be dried and smoked to make Chipotle chillies or pickled red or green to be enjoyed all year round! Whether you're prepping a zesty salsa, spicing up nachos or adding heat to tacos and burritos, Jalapenos are a must-have. Milder than many other chilli seed varieties, they’re a great starting point for those looking to build up their heat tolerance. The plants are easy to grow and produce excellent yields, making them perfect for beginner home gardeners.
