Description

(Zea mays) Flint corn. The World’s Most Beautiful Corn Plant! Invite this vibrant ornamental flint corn into your edible landscape design and you won’t regret it. Plants reach 6 feet, with foliage developing brilliant, multi-colored stripes of green, white, pink and yellow. Some stalks may be green, while others may be striped with all four colors. Wine-colored tassels and crimson-black kernels add a tropical touch to borders or container plantings. The sturdy stalks make a fantastic trellis for climbing ornamentals like sweet pea. When dried, the kernels grind into a tasty meal.

Native American flint corn was first brought to Japan by the Portuguese in the 1500s; at the time, flint corn was considered primarily a fodder crop for livestock. During the Edo period in Japan (1603-1867), officials of the centralized government (who were mostly vegetarian, for religious reasons) discouraged the consumption of meat and the need for corn to feed livestock plummeted, relegating the newly introduced corn crop to relative obscurity. With the Meiji period (1868-1912), meat was reintroduced to the Japanese diet, and the need for corn as fodder rose. Along the way, it was discovered that corn could be a tasty crop for humans as well. Striped Japonica was bred in Japan, and later introduced to America in the 1870s.

We have worked for years to find a pure strain of Striped Japonica, as most on the market were badly contaminated by GMO corn. After much effort, we may now present a strain that tested Non-GMO! Please enjoy this stunning treasure from historic Japan!

Growing Tips: Striped Japonica corn is a rare and stunning ornamental and edible variety known for its vibrant green, white, and pink-striped foliage. Beyond its beauty, it produces small, colorful ears with kernels often used for flour. Grow in full sun and fertile, well-drained soil enriched with compost. Plant in blocks of short rows for effective pollination and maintain steady watering during tassel and ear formation.

When to Grow

Plant Striped Japonica corn after the last frost when soil has warmed to at least 60°F. It thrives in long, warm growing seasons and performs well in most temperate regions with full sun exposure. In cooler zones, start seeds indoors in biodegradable pots and transplant carefully once soil warms.

How to Sow and Plant

Sow seeds 1–2 inches deep in nutrient-rich soil. Space plants 8–12 inches apart in rows 30–36 inches apart. Plant in clusters or blocks of four or more rows to ensure wind pollination. Keep soil consistently moist but not waterlogged. Thin seedlings to maintain airflow and strong growth. Avoid planting near other corn types to prevent cross-pollination if saving seed.

How to Grow

Provide regular watering, especially during tasseling and ear fill. Apply organic fertilizer or compost once plants reach knee height and again as tassels form. Striped Japonica corn is both ornamental and functional—its pink-striped leaves add garden color, while the small, dark ears can be used for culinary or decorative purposes. Harvest when husks turn brown and ears are firm.

How to Save Seeds

  • Corn is wind pollinated and will easily cross with other varieties (including GMO corn!). You will need at least 1 mile of isolation to avoid cross pollination. You can also use staggered timing or caging techniques.
  • Hand pick ears when fully dried on stalk. Seeds keep best if left on the ear; just remove at planting time.
  • Sweet corn seeds will remain viable for 2 years; dent corn will last up to 5 years when properly stored.

FAQ

Can Striped Japonica corn be eaten or is it just ornamental?

It’s both! While prized for its showy foliage, Striped Japonica produces small, colorful ears that can be ground into cornmeal or enjoyed as decorative corn once dried.

What makes Striped Japonica corn unique?

Its foliage features bold stripes of green, pink, and white—making it one of the most ornamental corn varieties. It also produces stunning dark crimson colored ears that add visual appeal to any garden.

How can I keep the foliage colors vibrant?

Ensure full sun, balanced soil nutrition, and consistent moisture. Avoid overfertilizing with nitrogen, which can reduce the distinctive striping and favor plain green leaf growth.
