I'm often asked about where carrot seeds come from, so I thought I would finally write a little section about that. The reason the majority of people don't know how or where the carrot seed originates from, is because most carrot crops are harvested before the plant reaches full natural maturity. While most of us pull up the plant and eat the root during the first year of development, carrot seeds are not produced until the second year of the plants development. Carrot plants are biennial. As the seeds are so readily available from most home gardening stores, there really is no benefit to hanging around for two years to develop the carrot seeds yourself, which also do require special care during that time to make sure they survive.
