Jalapeño M is a classic chilli pepper variety known for its thick-walled fruits, reliable cropping, and medium heat. The plants produce dark green peppers that can be harvested young or left to ripen to a rich red colour for a sweeter, fuller flavour.
This variety is well suited to greenhouse or conservatory growing and produces compact, blunt-ended fruits with a pungent chilli kick. Jalapeño M is a versatile choice for home growers and is ideal for fresh cooking, pickling, sauces, salsas, and drying.
With a manageable heat level of around 2,000–5,000 SHU, Jalapeño M is hot enough to add flavour without being overpowering.
