Japanese knotweed seed

LATIN NAME: FALLOPIA JAPONICA

COMMON NAME: Japanese Knotweed

The Japanese knotweed canes the tall, upright stems with the large, shield-shaped, green leaves and the long, arching sprays of the small, creamy-white flowers that open through the late summer, the hollow, bamboo-like stems with the reddish speckles rising fast into the dense, leafy thicket. The plant grows vigorously and spreads by the runners, and it stands the cold well. It likes the sun or the part shade, and the moist, well-drained soil. The young shoots rise early in the spring.

Scientific Research & Plant Biotechnology

In the buckwheat family, the knotweeds have a long, vigorous record in the studies of the colonising perennials, and the Japanese species appears in the research on the runner spread and the root chemistry. The pharmacologists value the root preparations, while the ecologists note the fast, dense growth. The seed biology fills out the picture, and the growers of the hardy ornamental perennials keep the species in their catalogues.

Ecological & Economic Value & Wide Applications

In the sunny border, the Japanese knotweed canes the tall stems and the cream flowers. The young shoots serve the spring greens for the ages, the arching sprays feed the bees late in the season, and the roots have served the traditional preparations. It grows well in the moist, well-drained ground. Bold, vigorous and late-blooming.

To grow the Japanese Knotweed from seed,

Scatter the seeds over the moist, gritty surface of the tray, then press them in gently, keep the tray in the bright, cool spot and mist lightly

Keep the tray bright and just damp, and plant the seedlings out in the open ground. The tall canes rise fast within the season.

. The seedlings rise within a couple of weeks, and they grow on fast. Settle the young plants in the moist, well-drained ground, and the bamboo-like stems will cane the border through the summer.
