Lettuce: Sow and Grow Guide- Deborah G.Verified BuyerRated 5 out of 5 stars11/21/25Delicious and easy to use
I often wrestle with growing lettuces. I find them hard to germinate and the leaves are often fragile and hard to handle.
This variety germinated vigorously and matured quickly. The leaves have a robust texture that's easy to pick and perfect in salads and sandwiches.

Growing this in 1 gal pots in our indoor grow room. Not our best performing variety, but worth growing for a little variety in the salad bowl.

I look forward to getting the zinnias in the ground. Soon. Then the watermelon. Still a bit early yet.

This is the first time I have tried your seeds. Actually just planted them recently-in South Carolina. We then get a snow storm-a rarity and nothing like it since 1989. My lettuce that was a few inches tall survived the storm
Unbelievable!
