A plant with rough or harsh qualities, though the specific botanical reference is unclear or archaic in modern usage.
A compound word from 'harsh' (Germanic origin) plus 'weed' (from Old English 'weod'). The combination suggests a plant known for rough or unpleasant characteristics, though this term is largely obsolete.
Medieval herbalists named plants based on their obvious characteristics—'harshweed' probably just meant a plant with rough, scratchy leaves or an unpleasant texture, much like how we still call plants 'ragweed' and 'nettles.'
