Okay, are they cute or what?
For years I’ve pulled hemp nettle “aliens” out of my garden — given a chance they run rampant. It grows quickly and will overtake everything around it. If there’s soil, hemp nettle will set up shop. If you’re a farmer it’s particularly bad as it competes with crops for moisture and soil nutrients.
Despite the term “nettle” I’ve never had a problem pulling them out sans gloves, although some sources say the tiny stem hairs can pierce the skin.
Classed as a noxious weed, it hitchhiked to Canada from Europe and Asia and was enjoying life in its new country by the 1880s.
Hemp nettle belongs to the mint family — square stems, tiny flowers, paired leaves. And volatile oils. No surprise that its relatives include basil, rosemary, thyme, sage, oregano and lavender.
I’d give hemp nettle a pass, though.
