Description
This mix of large varieties of Ornamental Corn, also known as Zea mays japonica, produces large ears composed of grains in various vibrant colours. They range from red, pink and orange to blue, among many other shades. Reaching a height of 2m (7ft) in one year, this annual grass likes sunlight, fertile soil, and water.
Zea mays japonica is a tropical annual plant with running roots from the poaceae family. Native to Mexico, Central America, Colombia, Venezuela, southern Colombia, Ecuador, Chile, and Brazil, it was the staple food of Native American peoples before the arrival of Christopher Columbus. This plant has rapid growth, reaching a height of 2m (7ft) and a width of 50cm (20in) in one season. It has a single, thick, woody stem with several 20cm (8in) internodes, bearing only one leaf per node. Each leaf is alternate on either side of the stem. The large, lanceolate, arching leaves have a waxy texture and measure up to 10cm (4in) wide and 1m (3ft) long. They are light green with parallel veins. In spring and early summer, male flower panicles, 20cm (8in) long, and axillary female inflorescences of the same size appear, followed by the formation of large, colourful grains with a diameter of 1cm (0in). The colour difference is due to the presence of plant pigments such as carotene (yellow, orange) and anthocyanins (blue, violet, red), which are present in smaller or larger quantities and superimposed in different seed tissues. All the grains are edible, regardless of their colour.
Ornamental Corn will. of course, fit well in the vegetable garden. It is easy to cut the corn, leaving only a few leaves, and dry the ear upside down in a cool and airy place. They are easy to sow in a greenhouse or directly in the ground, even by children.

Planting and care
Sow from March to May under cover in seed trays and pots, or in open ground in rows in May-June. Germination takes 14 days at 21°C (69.8°F). Transplant the young plants when they are large enough to handle, or thin out if sown directly in open ground. Maintain a distance of 50 cm (20in) between each plant. Cultivation: Maize has a running and shallow root system. It adapts to a wide variety of soils, even clay or limestone, but prefers fertile ones. It is a water-demanding plant that needs full sun.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
