Feral and ruderal Cannabis
Feral and ruderal Cannabis refers to populations of the cannabis plant (Cannabis sativa) that grow outside cultivation, whether as escapes from former hemp or drug growing that have become self-perpetuating (feral) or as colonisers of ground disturbed by human activity (ruderal). In Cannabis the two descriptions overlap heavily: most naturalised stands are both feral in origin and ruderal in habit, and the same populations are often labelled by either term.
Ruderal is an ecological category, a ruderal species being one that colonises disturbed, nutrient-rich and open ground, while feral is a statement of origin, a domesticate that has reverted to unmanaged growth. Populations of this kind tend to re-acquire or retain a wild-type syndrome of small stature, sparse branching, seed dormancy and readily shattering achenes that sets them apart from the crop they descend from.
This article treats feral and ruderal Cannabis as an ecological and population phenomenon. The formal taxon to which the wild and weedy plants of temperate Eurasia have been referred, and its contested nomenclatural history, are covered separately under Cannabis ruderalis. Such populations matter as reservoirs of genetic variation outside the cultivated gene pool, as the source of the day-neutral (autoflowering) trait now common in hybrid cultivars, and as agricultural volunteers and weeds, the low-cannabinoid feral hemp of North America (known as "ditchweed") being the most widespread example. read more →
