They often do pick to sell around here but the supermarkets, florists and the like only want them when the buds are tightly closed, the minute that they start to open thats the end of the flower harvest season. Often though in Lincs I think you will find that they are grown for bulb cultivation and not for the flowers, the same happens around here, there's more money in bulbs. I did see a field of about 40 acres with tulips in last friday but they were not flowering, a lot of monies worth in the ground there
