Cilantro ( Coriandrum Sativum) is a leafy herb which will grow flowers and produce seed in times of stress.
All parts of the plant are edible, even the root, which some areas of Vietnam use in recipes.
The whole plant is also known in the UK as coriander, but this maybe incorrect as the leaf is cilantro and the seed is coriander.
You can grow Cilantro in your garden in warmer weather, wait till the soil has had the last frost, or you can grow it indoors.
When space is at a premium then it is worth growing it hydroponically to increase the yield
