Hello,

Does anyone know where I can find some information on purple dead nettle?
Plants.usda.gov just gives some taxonomy.

Does anyone one know why it's called dead nettle? Something to do with
death or is it a corruption of some other language? Is it true that it's
presence indicates heavy metals (particularly lead) in the soil? From
hearsay, I've gathered that it tends to grow in 'wasteland' which makes
sense if the part about heavy metals is true.

Hopefully this is a good group to pose this question.

It's called "Dead Nettle" because, although it resembles Nettles
(Urtica spp.), and grows in similar localities, it has no stinging
hairs. Therefore it is "dead".
