I live in Florida, which is sub-tropical.
Bougainvillea are simply the most evil plant in the entire world.
They’re pretty, and ornamental, with nice red or purple flowers. But they grow like weeds, so you have to cut them back from time to time. They have 1–2” long thorns that will poke you like mad, and then the scratch will itch like a motherfucker for hours.
After two years of fighting with the dang thing, I finally chopped the plant all the way to the ground, cut it into tiny pieces, and burned it – cackling maniacally and howling at the moon as it died its slow, painful death.
Gods, I hate bougainvillea.
