Coriander is an annual plant that should be grown from seed each year into its final growing position. They can also be started in pots under cover, but don’t plant out until the risk of frost has passed.
Leaves can be harvested as soon as the plants are big enough, and if left to go to seed in the autumn, you can easily collect the seeds which are also great for use in cooking (and don’t forget to put some to one side for planting again next year).
Coriander can also be gown quite successfully in containers, and its growing season can be extended by sowing some into pots and growing indoors over winter.
Sow seeds into pots or directly into the ground every few weeks between spring and midsummer to provide a succession of coriander throughout the season.
Both the seeds and leaves are commonly used to flavour dishes, and both have a very distinct and very different flavour.
