Pastel ribbons of sweet peas stripe the floor of Lompoc Valley, California, the world's major growing area for flower seeds. Lompoc has an ideal cli mate: eight frost-free months a year, constant winds to aid pollenation, and morning and evening fogs for moisture. Racing the wind, harvesters gather feathery geranium seeds with a vacuum before a breeze can carry them away. They haul machines through a field near San Juan Bautista, in central California.
