Fantastic! I will be ordering from Sandiaseed from now on.

Germination for nearly all of my varieties was 3-5 days (95% - 100% success rate). My varieties include: Red Ghost, Carolina Reaper, Trinidad Scorpion, Devils Tongue, Cayenne Ring of Fire, Habenero Red, Yellow Jamaican, Paprika Numex, and Bolivian Rainbow. Another thing that I really appreciated is that each packet seemed to contain 20% more seeds than indicated (each 10 seed pack contained 12 seeds) - Not sure if that is standard but it was a nice bonus.

Sun Gold F1 Tomato Seeds

I grow these for habanero hot sauce

I've found that when you combine roasted carrots, habaneros, lime juice and garlic, it will make the best hot sauce of your life. I think it's the sweetness and depth of the carrots that make the sauce even better, and pairs perfectly with the habanero heat. I got the inspiration from one of my favorite store-bought hot sauces, Marie Sharp's Habanero hot sauce. Sometimes I add some of your Chef's orange tomatoes too to make more of it, and they also give more flavor to the hot sauce and help tame the heat a bit. I grow these in my garden every year along with your orange habaneros, orange tomatoes and other hot peppers and veggies. Very reliable.

Carrot - Danvers Seeds

Like flowers!

These fabulous peppers added lots of color to our patio pots. So pretty in multiple colors, plus you can pick them and add to salsa for a nice spicy kick. These are fun in any ornamental edible garden.

Bolivian Rainbow Pepper Seeds

Made really tasty hot pepper flakes

We let these hang dry, then ground them up – they made the tastiest pepper flakes. They have a nice kick, but good flavor too. Easy to grow plants, pretty peppers.

Our family's favorite chile!

Great seeds, good germination, plants grow quickly and produce lots of pods for roasting. Great flavor and just the right amount of spice. We grow these every year in our garden in Utah.

Cherokee Purple Tomato Seeds

Great germination rate!

These germinated in two days. I started them in midsummer and they fruited by late fall in my zone 10b garden and are overwintering just fine. I’ll have more to harvest by late spring. I made my red sauce for pozole for Christmas with my harvest!

Guajillo Chile Seeds

Big Jim Chiles

Big Chiles with just enough heat to add to green enchilada's. The flavor after roasting is fantastic. Since green chile roasting is not a local thing in Eastern Washington we us a weed burner. The smell of roasting peppers is heavenly.

Pueblo Chili

My favorite green chili to grow. Plenty of heat and after roasting sit perfectly on a hamburger. Also my wonderful wife makes Puelo Chili jam that is a real crowd pleaser

Mirasol Mosco Pueblo Chile Seeds

Beautiful and spicy

I was looking for a spicier New Mexico red chile and this was awesome! It is a beautiful looking pepper and the taste is superb.
