Yes, that is the lettuce I grow every year. I just planted a new patch today, since our older patch is ready to harvest. I also get the butter crunch lettuce to use in salads.
There is a nursery I pass on the way to the farm and they sell bulk seed. I can get $.75 of seed that will last for us two full years. I gave some seeds to my neighbor and he has a nice bed of lettuce as well.
Sometimes I let one of the lettuce plants go to seed and collect it for the next year, just to see if I can. Also, because I hate to have to leave the house.LOL
