Pepper jalapeno San Joaquin F1
2023 AAS Edible - Vegetable Winner
Pepper jalapeno San Joaquin F1

This new San Joaquin jalapeno pepper will make gardening so much easier! This is a determinate jalapeno that sets most of its fruit in a short window so there is a generous (~50 fruits per plant) number of fruits ready all at the same time. Perfect for canning, pickling, and making roasted stuffed jalapenos for a crowd. But no worries if you won’t need them for a while as they hold their firmness and taste until you are ready to harvest. Judges loved the flavor of the thick-walled fruits that have just a hint of heat at 2500-6000 Scoville units. Leave them on the plant longer for a beautiful red, and still delicious, jalapeno.

Water-in transplants using a high phosphorus solution.

    This is a commercial variety that is meant for the processing industry.

    San Joaquin provided a continuous supply of jalapenos for my husband’s trademark poppers, our go-to appetizer when guests come to visit. He slices them horizontally, scoops out the seeds, then sautees his home-made chorizo with chopped onions. The meat mixture is added to cream cheese and sharp cheddar and used as a filling for the pepper halves. Bake until brown and bubbly and viola! or it is Voila? Anyway, you know what I mean.
