|“|| ‘Bless me, Mr. Frodo, but I didn't know as anything grew in Mordor! But if I had a'known, this is just what I'd have looked for. These thorns must be a foot long by the feel of them; they've stuck through everything I've got on. Wish I'd a'put that mailshirt on!’
‘Orc-mail doesn't keep these thorns out,' said Frodo. ‘Not even a leather jerkin is any good.’
–The Return of the King, The Land of Shadow
Stabbing Thorns are brown plants found throughout Mordor. The only thing that distinguishes these plants from dead marsh plants are their colour and the fact that when walked through, they cause 2 () damage to all players and non-Mordor creatures (hence their name). Only Mordor creatures are not hurt by it.
Stabbing thorns can be picked up with shears, but otherwise, they'll break when hit. Like withered moss, they can only be placed on Mordor rock or dirt. It can also be planted into a flower pot. Probably the only thing these plants can be used for besides decoration is an odd form of home defense, as it is completely feasible to drop home intruders into a pit of these.
The anglo-saxon thorn-rune ᚦ (= letters TH) means "thorn" (what else?). Tolkien used those ᚱᚢᚾᛖᛋ for some texts in the initial drafts of "The Lord of the Rings", later on, he replaced them by cirth runes.
|“|| ᚦ The thorn is exceedingly sharp,|
an evil thing for any knight to touch,
uncommonly severe on all who sit among them.
