Zea mays 'Multicolor Hybrids' Spectacular ornamental corn with brilliantly coloured decorative cobs Zea mays 'Multicolor Hybrids' is a spectacular ornamental corn grown for its highly decorative cobs packed with brilliantly coloured kernels. Each cob develops its own distinctive combination of colours, including shades of red, orange, yellow, blue, purple and cream, creating an impressive mosaic effect that becomes especially striking as the cobs mature and dry. Growing to approximately 150 cm tall, the strong upright plants also add valuable height and structure to summer borders. The colourful cobs mature towards autumn and are particularly prized for harvest decorations, dried arrangements, wreaths and seasonal crafts. Once properly dried, they retain their rich colours for a long-lasting natural display.

Corn is wind-pollinated, and group planting helps ensure good pollination and well-filled decorative cobs. ● Choose the warmest, sunniest and most sheltered position available, as corn needs plenty of warmth and sunshine to mature its cobs successfully. ● Water consistently once plants are actively growing, paying particular attention during flowering and cob development. ● For dried decorations, allow the cobs to mature fully until the kernels become hard, then harvest and dry them thoroughly in a cool, dry and well-ventilated place.
