Easy to grow, great for pesto and caprese salads

I grow your basil seeds every year, they are easy to start from seed and grow into nice bushy plants that we harvest all summer long to use to make caprese salads (when the tomatoes start to ripen), as well as pesto. I like to make a big batch of pesto, then freeze "pucks" of it in a muffin tray to store in a container in the freezer for some summer flavors all winter long. These seeds always have great germination. I also like to let a couple of basil plants bloom as the pollinators love the blooms and they are pretty, too!

Basil Genovese Seeds - Sweet Italian Heirloom - Great Flavor and Aroma

Worth every penny!!! Best large chiles!!!

Bought the Green Chile Intro - 3-Pack and was able to start indoors the Big Jim Legacy and Sandia Select with a 100% germination rate thanks to the clear instructions provided. As of Mid July in NC zone 7A on the 8 chile plants(6 Big Jim, 2 Sandia) in the garden I have 5-7 large chiles per plant. The smallest chiles are over 7” and I’m already getting another flush of flowers for round 2 of delicious peppers. Highly recommend these chiles!!!

Gift for my sister

My sister loves gardening, and is quite a seed collector and grower. She'll love all these classic varieties to add to her garden and seed box. Zucchini are an old stand-by, as well as pumpkins, beans, radishes and more. She's never grown spaghetti squash, so that will be a fun addition.

Beautiful, perfect golden tomatoes - very tasty, too!

Perfect looking tomatoes in a golden color with hints of red, they are gorgeous. These Rainbow Tomatoes were definitely the most productive tomatoes of the season last year, so our countertop bowl was filled with their golden deliciousness.

Make sure to use a sturdy tomato cage (not those wirey floppy ones that they most commonly sell!) - we ended up using some wood stakes to create a frame around the plants as they were so huge and loaded with fruit later in the season.

We just planted our seedlings for these this year, looking forward to watching them grow!

Big Rainbow Tomato Seeds - Big Beefsteak Heirloom - Juicy & Sweet

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 - Delicious Sweet Cherry Tomatoes

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.

Cherokee Purple Tomato Seeds - Heirloom with Sweet Flavor - Heat Tolerant

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!
