Datisca cannabina | False Hemp

$0.00

DESCRIPTION
Datisca cannabina, also known as false hemp, is a tall perennial that produces feathery clusters of yellow-green flowers in late summer, adding an airy, textural element to garden beds. The plant’s slender, pendulous flower clusters are complemented by deeply lobed, fern-like foliage, giving it a lush, ornamental quality. Its blooms mature into delicate, tassel-like seed heads that lend additional visual interest through autumn.

Native to regions stretching from the Mediterranean to the Himalayas, Datisca cannabina has a history of being cultivated for its resemblance to hemp and its traditional uses in dye-making. This robust plant is well-suited to naturalized or wildflower gardens, where its height and distinct form can create a soft, natural screen or provide vertical interest. Its unique foliage and flower structure make it a visually compelling choice for gardeners looking to add depth to informal, wild-inspired plantings.
