F1 seeds in the garden are produced from a specific cross between two known parents to produce a plant with known characteristics. It could be colour, height, uniformity of maturity, or anything.
When someone comes on this forum and says 'What can I do, all my broccoli has flowered?' 10 to 1 they used F1 seed and every plant matured at the same time.
If those F1 plants in the garden are pollinated by bees which collected pollen from random plants in other gardens, the resultant offspring could have equally random charteristics. Some good, some middling, some rubbish.
