The Pumpkin (Spice) Jalapeno is a NuMex-bred open-pollinated variety that produces small, round, pumpkin-shaped jalapeno peppers. They mature to a beautiful orange color and pack mild to moderate heat (2,500–5,000 SHU). This is a unique novelty pepper — eye-catching in the garden and a conversation starter at the farmers market or dinner table. The squat, ribbed shape looks more like a tiny pumpkin than a traditional jalapeno.
All common garden peppers — jalapenos, bells, Anaheims, paprikas — belong to the same species: Capsicum annuum. They can and do cross-pollinate, primarily via bees and other insects. The fruit you harvest this year won't be affected (the mother plant's genetics determine the fruit), but the seeds inside may carry crossed genetics that show up next generation.
