I had a little plant show up in my yard in California one time. It was so pretty, I let it grow. Within a couple years, it was 50 ft. x 50 ft. and had eaten an entire Oak tree.
I put on my boots, gloves and long sleeved shirt and got out the shovel. Man, what a job! I was happy for the boots and gloves by the time I dug up my 3rd rattlesnake. And I chased rats all over the yard, probably why the snakes were there.
