The burning sensation tapers off in severity after a few minutes, but its after-effects (particularly felt when the afflicted part is put under hot water, or subjected to heat) can last up to a whole day. The chemical is formic acid (the same chemical in ant stings), which is injected by tiny hollow hairs covering all the aboveground plant parts.

If you don’t want to touch it, just look closely for densely packed hairs on the leaves, which become larger and more sparse on the stems, almost appearing like spines. But that’s not a fail-safe ID method unless you have otherwise familiarized yourself with its…
