I hate how this plant takes over everything when it's not in it's natural habitat. It's one of the worst weeds in Brisbane, Australia. One plant produces thousands of seeds. The plants are rhizomatous, so you have to dig it out of the ground to kill it. They climb up and over trees which blocks out light for any smaller native plants trying to grow.
HAHA it's funny you say that as I killed my last beauty when my cat wouldn't stop peeing in it. I wish they grew like weeds for me hahahah
maybe you just need some huge native giant cats
There were giant animals in Australia thousands of years ago, but humans killed them all.
