Corn is widely cultivated for its edible seed, especially in tropical and warm temperate zones of the world, there are many named varieties. Unfortunately, the plant is not frost tolerant and so needs to be started off under glass in Britain if a reasonable crop is to be grown. There are five main types:- Sweetcorn is of fairly recent development. It has very sweet, soft-skinned grains that can be eaten raw or cooked before they are fully ripe. Cultivars have been developed that can produce a worthwhile crop even in the more northerly latitudes of Britain if a suitable warm sunny sheltered site is chosen. Waxy corn is used mainly in the Far East. It has a tapioca-like starch. Flint corn, which shrinks on drying, can have white, yellow, purple, red or blue-black grains. It is not so sweet and also takes longer to mature so is a problematic crop in Britain. There are many other uses for this plant as detailed below. Dent corn has mostly white to yellow grains. This and Flint corn are widely grown for oils, cornflour, cereals and silage crops. Corn grows well with early potatoes, legumes, dill, cucurbits and sunflowers, it dislikes growing with tomatoes.
