maybe.... and i don't say this to be mean or to hurt plants... but maybe it is a gift to heal - that you can heal by beating the plant into bits. destroy it and the trigger? have power over the trigger by being more powerful than it?
(mind you, a trigger/phobia of mine is 8-leggeds; if some one gave me one as a gift they'd have to take it out with them immediately).

or have someone that likes cacti come and get it.

put it out on the road with a "FREE" sign in it.
