Jalapeño M

I pretty much use Sandia seeds exclusively! A few years ago I just happened to order your Jalapeño M. To me it's the perfect Jalapeño! Really nice size! Perfect heat for what we like! Wonderful flavor with a meatyness that's perfect for many different uses! I make my own Sriracha so I wait for them to turn red. They're one of my base peppers for my sauce! I praise them to all my personal friends and to members of groups that I belong to!

Jalapeño M Pepper Seeds - ON SALE

Seeds arrived quickly and packaged well. Happy with price. Still in growing stage

they have all sprouted

ask me again in a few months. Using heating pad, and covered seeding tray with about 16 hours of light every day. Each one is maybe an inch tall right now

Excellent pepper

Perfect germination with a warm pad indoors, very vigorous plants. We just did our first pickle and I had some raw and they are spicy and flavorful even when relatively young. Looking forward to eating way too many and having spicy gut.

Awesome peppers!!!

Boy were these peppers amazing! About seven months after I planted the seeds, I picked a pepper and cut it up into thin slices and put those on my sandwich, and boy was it good!!!

Best Jalapeno Seeds

These are my favorite jalapenos to grow – they are abundant and nice and spicy. I've been growing these jalapeno seeds for the past five years, and have never been disappointed. Thank you!

Nice and spicy

Large size makes these great for poppers. Great seed germination. These have earned a new permanent place in my garden I grow from seed.

Española Improved NuMex Chile Seeds - Robust Flavor and Early Maturity

Dynamite xx Hot peppers, 4 heat lovers only!

I had looked high & low, and searched the web with many word combinations ‘looking’ specifically for my favorite chili, the Dynamite xx Hot… so I could grow my own. The peppers were sold in Colorado at select places during roasting season, but you couldn’t buy seeds for them… anywhere!
Finally, as luck and persistence would have it, I discovered Sandia Seed Company.
Thank you Sandia! I planted them and had a great crop this year. I plan on growing them every year as well as trying some of their other seeds,

Dynamite Green Chile Seeds - Extra Hot Variety at 12,000 Scoville

Prolific Peppers!

There's just something fun about growing a jalapeno that is light enough in color that some people think it's a banana pepper. LOL! I picked these just for color variety, and I'm very pleased that my plants have been loaded with them all season! We donated about 50 lbs of mixed peppers this year from our garden and I still had enough to freeze some and can more jars of recipes than we'll probably be able to use before next season. All my peppers were from Sandia Seed Company. I've never had such great pepper production before using these seeds!!

Tasty and prolific

This spinach germinated well, and produced way more spinach than I'd initially expected. It grew really well, was slow to bolt in the summer, and has a really nice mild flavor for salads or steamed.

Awesome peppers!

This was my first time growing these and I will definitely be growing them from now on. Great germination and very sturdy plants that have withstood some really high winds. Huge long peppers that are excellent green or red, very easy to peel skin.

Jalapeno to Chipotle

I got these to make Chipotle chilis. These fruit early and are mild-ish when green, but when they ripen, they are perfect for smoking and drying with great flavor and nice heat. Don't plant too many as they are quite prolific.
