Corn of Many Colours

All About Corn

Corn (Zea mays) is also known as maize. In addition to being delicious, nourishing and fun to grow, corn, particularly the coloured varieties, is highly ornamental; cobs can be dried and used as decorations in the home.

Heritage, or heirloom varieties of corn are far less sweet than modern cultivars, which is to be expected, their value being a lot broader than just sweetness of grain. Keeping varieties pure and saving seed is now very important. To save heirloom corn seeds, plant each variety at least two kilometres apart or at least at one month intervals to prevent cross-pollination.  Plant in blocks as plants need to be close for wind pollination.

There are many categories of corn. The five main ones are Sweet Corn, Flour Corn, Popcorn, Field Corn and Flint Corn. Other categories include Waxy Corn, Slender Corn, Ornamental Corn, and Pod Corn.

Note: We only send our corn seeds within Australia.

There are basically two types of popcorn: round pearl kernels usually produced on large ears and sharp-pointed rice kernels usually produced on small ears. Pearl type (what you usually find commercially) produce large whole hulls when popped. Rice types produce smaller popped corn but it is tender and has little or no hull (that thing that gets caught in your teeth). Rice types are especially prized by home gardeners or can be purchased in specialty shops.The modern varieties of yellow and white popcorn have been bred and altered to produce large yields, easy harvest and popping volumes. Heritage varieties sacrifice all that to grow varieties that focus on taste, texture and overall eating quality.

These are edible when still unripe and soft, but they are usually used ripe and dry for decoration purposes. Easily grown in any rich, well drained soil in full sun and plenty of watering during the growing period.
