Mimosa diplotricha, also known as the giant sensitive plant, is a species in the Fabaceae family.
A native from Brazil, it is extremely invasive in the Pacific, where it has been introduced on all island groups, except (so far) Tonga. It was introduced on Niuē around 2000, but an ongoing eradication program has virtually destroyed all occurrences there.
Left undisturbed, the plant can grow 2 meters high and its big and sharp spines make it indeed a very unwelcome guest.
