Lactuca sativa Black Seeded Simpson Lettuce
Lactuca sativa Black Seeded Simpson Lettuce is a legendary heirloom loose-leaf variety, cherished for its rapid growth, delicate texture, and exceptional heat tolerance. Growing to about 9 to 12 inches tall with a spread of 10 to 12 inches, this variety is perfect for kitchen gardens, raised beds, and container plantings where reliable, early harvests are desired. Unlike heading lettuces, Black Seeded Simpson forms a loose, upright rosette of crinkled, light-green leaves that can be harvested as baby greens in as little as 3 weeks or allowed to mature for a full-sized harvest in just 45 days.
Culinary and Practical Uses
- The crinkled, chartreuse leaves possess a crisp, juicy texture and a sweet, mild flavor that never turns bitter, making them the ultimate base for fresh spring salads.
- Excellent for "cut-and-come-again" harvesting; outer leaves can be snipped for sandwiches and garnishes while the center continues to grow.
- Rich in Vitamin A and K, this variety adds both nutritional value and a vibrant pop of bright green color to tacos, burgers, and wraps.
Characteristics
- Foliage: Large, frilly, light green to yellow-green leaves with a crumpled surface; the texture is famously tender and delicate compared to stiffer romaine types.
- Growth Habit: Open, upright, loose-leaf rosette that does not form a tight heart; renowned for being one of the most heat-tolerant and bolt-resistant leaf lettuces.
- Flowers: Produces tall central stalks with small yellow dandelion-like flowers if allowed to bolt in extreme heat, signaling the end of the vegetative cycle.
- Seeds: Harvested after the flower fluff dries; true to its name, this variety produces distinctively black seeds, unlike the white seeds of many other Simpson strains.
Growing Requirements
- Sun: Thrives in full sun during cool weather but benefits significantly from partial shade during warmer months to prolong the harvest.
- Soil: Prefers loose, cool, fertile soil rich in organic matter; well-draining soil is essential to prevent rot.
- Water: Requires consistent, even watering; lettuce is shallow-rooted and needs moisture to maintain its sweet flavor and crisp texture.
- Spacing: Plant seeds in wide rows or thin plants to 6 to 12 inches apart to encourage full-sized bunches; crowd closer for baby leaf production.
- Maintenance: Practice succession planting every 2 weeks for a continuous supply; mulch to keep soil cool and weed-free.

This is a great blanket for those who prefer to be cool all night.
This is a great blanket for those who prefer to be slightly cooler all night. I have been using this for almost two months now. It's been difficult to figure out how to explain it's use. Ultimately I have figured out that it acts like a blanket, insulating and keeping you warm, however, wherever the blanket is actually resting on your skin stays cool. It took me a while to figure it out. How does an insulating blanket cool you? I'm not sure how the material actually works, but that is what it does, at least for slightly cool interior weather with a bit of humidity. I imagine in the desert it may work differently. I would say nights when a sheet may be too cold or thin, and a blanket way too hot, this is the in between.
The material itself is soft and almost silky. It is made well, has a pleasant appearance on the bed, and doesn't wrinkle. So getting up in the morning it is easy to toss and make the bed. It breathes unlike a duvet cover and feather blanket, so no need to air it out so much.
I have come to really love it and recommend it for anyone looking for an in between, between a sheet and comforter. I have never woken up sweating or pulling it off at night. My only experience was at first thinking I was cold but learning that I was not, only where my skin was in contact!
For the quality and price, it is definitely worth giving it a try!

Attractive Comforter That Will Keep Hot Sleepers Cool
The Bedsmile striped cooling comforter ice blanket for hot sleepers is amazing. It's cool and comfortable thanks to its unique structure. If you're a hot sleeper, then this comforter is definitely the one for you.
This comforter gives you the comfort of a blanket, but manages to also keep you cool throughout the night. It's soft and it feels cold to the touch on one side and smooth and comforting on the other. This is because one side is made from nylon which feels cool because it's a synthetic, thermally conductive material that quickly draw heat away from your skin. My daughter is the lucky recipient of this comforter, and she loves it. It matches perfectly with the gray sheets and pillowcases she already has.
I have to admit I had my doubts when I first pulled it out of the package and saw it wasn't thick like a traditional comforter, but so far it has exceeded my expectations. The design is very attractive, gray with white stripes on one side, and a solid gray on the other. It is the solid gray side that is made of nylon for that cooling effect.
It’s lightweight without feeling flimsy, and it is well-stitched. This is a quality comforter made with top of the line material. It's Queen size and its measurements are true. The ad says it is "reversible" but the solid gray side is nylon and that is where you get the cooling benefits...plus, it looks so much better with the gray and white strips on top.
I'm really happy with this bedspread, it looks great, it is made with quality materials, it is soft and silky and it does keep you cool and comfortable at night. If you're looking for a good nights sleep, I highly recommend this comforter.

Quality design, materials, and stitching...with one annoying trait
There is a lot to love about this comforter.
First, as advertised, it works. I don't know how, but on a warm day in the house it feels great to cover yourself in it and to feel its "coolness."
The design is cool as well, but in a stylistic way. It's elegant and tasteful, and the colors went well with our mocha-colored walls. And the fabric color is neutral enough that it will go with a large range of colors.
The fabric has a high thread count, so it looks, feels, and is luxurious. Stitching is perfect.
Overall, the design and materials are superior...with one--for me, anyway--annoying characteristic: we couldn't keep the comforter on the bed. The backing material is so very smooth and shiny that the moment it was disturbed even in a slight way, this lovely blanket went instantly to the floor night after night, sliding down on that smoothness and shininess.
As a result we keep it kind of rolled/folded up in the middle of the bed during the day (which is a shame because the design is so nice), and we find ourselves frustrated at night when it invariably slides off the bed!
All told, this is an elegant, quality made comforter. I almost knocked a star off for its seeming inability to stay on the bed. But it looks so nice, is so well made, and actually works, that it deserves a 5-star rating. Just be ready to grab it quickly when it starts its quick slide to the floor in the middle of the night.
A good value. Recommended.

Nice for cooling but not so cool with staying on the bed
Color: Black Pinstripe, Size: King(108"x90")
Definitely cooled while sleeping however due to the silky fabric it did not stay on the bed and often ended up on the floor by morning.

Pretty nice blanket
First off I have to say that this is not exactly a cooling blanket. It is true that when you first get under it, it does feel cool. Shortly thereafter though, wherever the blanket makes contact with you it warms up to your body temperature, so it doesn’t remain cool. Still, I just moved my foot to a different area and hit a cool pocket, so it has its moments. I have to say I really like the weight of this blanket. It’s so hard to find a good blanket, that is not that thick, It is thin, which is exactly what I was looking for since I live in Florida. One side of the blanket is the “cooling“ side which is plain gray, and on the other side is a gray and white striped pattern. I’m not really crazy about the pattern to be honest. I wish this blanket came in more colors or patterns. The blanket fit my queen bed nicely - not too big or too small. For what it is, I’m not really sure I would say it’s good value for the money, but I do like this blanket.
