Hatch Red Medium - Joe E. Parker Chile Seeds - Popular Heirloom with Great Flavor

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!

Serrano Hidalgo Seeds fromSandia Seed produce even in the HOT drought of central Illinois this year! I love adding a little Mexican kick to my salsa but also tossing these on the grill! They have great flavor and produce all summer long!

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.

Hatch Green Medium - Big Jim Chile Seeds - Nice Heat & Great Flavor

Wow! BIG JIM PEPPERS

Growing these in Florida, (Recent transplant of NM).
Lovely peppers. Took a couple weeks is all and wow! I have several budding; 2 large enough to nickname. They're still in their infancy, but I can tell they are going to be great! Love the seeds!

Pruden's Purple Tomato Seeds - Old Family Heirloom - Sweet Taste

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.
