Lettuce flowers are actually inflorescences made up of 10-25 florets, which are all receptive to pollen for a few hours on the same morning. The structure of the flower almost always leads to self-pollination, though a very small percentage of cross pollination from insects is possible, so John Navazio, author of "The Organic Seed Grower: A Farmer's Guide to Vegetable Seed Production" recommends 10-50 feet of isolation between different lettuce varieties depending on crop type and barriers that may be present in the landscape. #lettuceflower #lettuceinflorescence #lettuceflorets #seedsaving #selfpollinate #isolationdistance
