This is a Pepper Joe's special hot pepper rarity! Guam Boonie peppers are tiny Guamanian heirlooms that will surprise you with a very intense, upfront heat! Don't ever sleep on the small peppers - they're the ones that can pack the most serious punches!

Guam Boonie pepper plants can stretch up to 3 ft. tall and produce loads of these 1" fiery pods. Related to the Malagueta and Thai Bird Chile, they share similar characteristics. Guam Boonies share the shiny, smooth, bright-red skin of the Malagueta pepper, while it shares its small, conical size with the Thai Bird Chile. Boonie pepper plants love lots of sunlight and space to grow, so make sure to provide a great space for them to flourish!

These super tasty sweet gems are backed by incredible heat. This is the main attraction for Guam Boonie peppers, as the punch will linger on your tongue and lips 4-7 times longer than jalapeno! The heat actually amplifies when you dry and crush these pods into chili powder or pepper flakes. However, Guamanians love to eat these peppers fresh or in cooked foods. Save your harvests for later by freezing them - don't worry, they're good to last!

*Non-Isolated - Disclaimer: While some of our varieties marked non-isolated were isolated when grown, they are an unstable pepper seed variety that may produce plants with genetic variations, making them less predictable and consistent in terms of traits such as flavor, size, and heat level. While this can lead to unique and exciting variations, it's important to note that these seeds may not reliably reproduce the same characteristics from one generation to the next. Planting non-isolated/unstable pepper seeds can be an adventurous gardening experience, but be prepared for some degree of variability in the resulting pepper plants. We will not be able to offer replacements for variation in traits.

Great Products

I ordered Boonie Pepper seeds and they were sensitive to grow but I finally got a few to grow and about 8" tall now. The Reaper Snack Sticks are really good. They have a bite but nothing like a piece of reaper pepper. I usually eat about 1/5 a stick as a quitc appetite suppressor. I keep them in the frig. after opening. I ordered the Jalapeno Summer Sausage and it's delicious. MY FAVORITE IS THE HABANERO PEPPER MUSTARD. it is awesome and great to dip in pretzels or on a baked / toasted pretzel. It's great on a cracker and a little cream cheese. I'm planning on ordering the Ghost Pepper Mustard as well.

  • What You'll Need

    Soil and Tray Method

    Seed Starting Supplies 
  • Plant your Seeds

    1. Pre-saturate your seed starting soil mix. Ensure the seed starting mix is fully saturated prior to planting your seed.
    2. Make a ¼-inch hole in the center of each seed starting cell. A #2 pencil eraser is a great tool for making these holes.
    3. Place your seed and cover gently with soil.
      You can plant up to 4 seeds per cell to help ensure successful germination.
  • 4. Place your heat mat under  your base tray and your humidity dome on top. For best results, set your temperature controller between 75 - 80 degrees.

    5. Place your plant light above the seed starting tray and turn on. Refer to the plant light manufacturers instructions for the optimal distance. Plant light should remain on for 14 to 16 hours per day.

    6. Enjoy watching them grow! See our full instruction page below for more information.
