They start out green but ripen to bright, sunny yellow. Pick at both stages for a colorful jar of pickled peppers! This jalapeño rates around 2,500-5,000 Scoville heat units (medium hot).

Growing Info
Harvesting: Harvest when mature size and firm. 'NuMex Lemon Spice' can be harvested green, although, when allowed to fully turn to bright yellow it is considered to have the most complex flavor. When harvesting, take care to avoid touching the interior of any broken peppers, as the capsaicin is an extreme irritant, especially to the eyes. Wash hands thoroughly after harvesting or wear gloves to harvest peppers.

Taste great, but I bit into one thinking it'd be like a jalapeno and it was more like a habanero...maybe it was cross pollinated with something else I had. Will be having these again next year.

Loved this pepper! At green they taste just like a regular jalapeno and at yellow they taste both sweet and spicy. I started it late and put it in a less than ideal location with ~5 hours of direct sun, but it still produced several peppers. Looking forward to growing it again this year in a better location for a better yield!

18 out of 20 seeds successfully germinated and I transplanted the 11 strongest to larger planters. The flavor is very good, spice is slightly more mild than typical jalapenos, and these pair well with many foods (especially breakfast foods). All plants have multiple peppers 4 months after first sowing the seeds, though none have begun changing to yellow as of 7/6/24

I'm so excited seeing the flowers and then peppers come in! Can't wait to harvest.

I can't believe I grew them from seed! I have two grow bags with two in each. One bag has started growing 2 peppers. The other bag is starting to push out the flowers. I can't wait to see them true yellow!
