Details

Conyza canadensis is a herbaceous plant, erect, branched in its upper part, and sometimes also from its base

Its leaves are elongated, narrow, pubescent, frank green, and slightly sticky : The whole plant is aromatic and resinous, and its contact may cause skin reactions

During summer, small flower heads appear at the top of the plant

Flowering is quickly followed by the release of a multitude of seeds carried by the wind

Canadian horseweed likes heat and sun, and will strive even during drought

It is a pioneer plant that grows on poor, rocky, and abandoned soils, such as scree, industrial and forest wastelands, roadsides, crevices along sidewalks, etc.

WARNING !
Conyza canadensis is a very invasive species
Prevent its uncontrolled spread by harvesting before it produces seeds

Yet, we offer it in the catalog because it has very interesting dyeing properties, which were known and exploited by the Amerindians

Very intense, and extremely wash and light fast, Golden Yellows, can be dyed at a very low WOF ratio

Erigeron canadensis is also a plant with medicinal properties: Anti-inflammatory, Anti-rheumatic, Astringent, Diuretic, Emmenagogue, Hypoglycemic, and Vermifuge

Cultivation

Sow the seeds in late spring

Don't sow them too early : They would not sprout until it gets hot

Tamp them on the surface of a moist potting soil, in godets

Plant in the final location a few weeks later, when the plantlets are sufficiently developed

Harvest the leafy stems when they begin to branch out to flower

We strongly recommend that you uproot the plants before they make seeds, and destroy any unused waste
