Botanical description
Maize stems superficially resemble bamboo canes and the internodes can commonly be 7 inches. Maize has a distinct growth form, with the lower leaves being like broad flags, generally 50?100 centimetres long and 5?10 centimetres wide (2?4 ft by 2?4 in), the stems are erect, conventionally 2?3 metres (7?10 ft) in height, with many nodes, casting off flag-leaves at every node. Under these leaves and close to the stem grow the ears. They grow about 3 millimetres a day[18].Uses

Medicinal uses(Warning!)
The corn silks are cholagogue, demulcent, diuretic, lithontripic, mildly stimulant and vasodilator[19][20][21][22][6]. They also act to reduce blood sugar levels and so are used in the treatment of diabetes mellitus[20][6] as well as cystitis, gonorrhoea, gout etc[23]. The silks are harvested before pollination occurs and are best used when fresh because they tend to lose their diuretic effect when stored and also become purgative[20]. A decoction of the cob is used in the treatment of nose bleeds and menorrhagia[6]. The seed is diuretic and a mild stimulant[19]. It is a good emollient poultice for ulcers, swellings and rheumatic pains[19], and is widely used in the treatment of cancer, tumours and warts[6]. It contains the cell-proliferant and wound-healing substance allantoin, which is widely used in herbal medicine (especially from the herb comfrey, Symphytum officinale) to speed the healing process[23].
The plant is said to have anticancer properties and is experimentally hypoglycaemic and hypotensive[6].Ecology

Propagation
Seed
Seed - sow April in individual pots in a greenhouse. Grow on quickly and plant out after the last expected frosts. A direct outdoor sowing, especially of some of the less sweet varieties, can be tried in May. [Britain]
Cultivation
Corn is widely cultivated for its edible seed, especially in tropical and warm temperate zones of the world[25], there are many named varieties[27]. 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[9]. Popcorn is a primitive form with hard-skinned grains. When roasted, these grains 'explode' to form the popular snack 'popcorn'[9]. Waxy corn is used mainly in the Far East. It has a tapioca-like starch[9]. Flint corn, which shrinks on drying, can have white, yellow, purple, red or blue-black grains[9]. 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[28][29][26], it dislikes growing with tomatoes[29].

Cucurbita (Squash)
All vine species of the genus Curcubita can be intercropped with Zea mays. If the latter is not planted too densely, the thin leaves allow plenty of light to reach the ground and vines of the former can spread and its large leaves provide ground cover to retain moisture and prevent compaction and nutrient leeching from rain.Polycultures & Guilds
