Hello all. I moved into a new house about 8 months ago and have lots of plants growing that I'm not sure what they are. I'm new to gardening. I was able to identify most plants with an A-to-Z garden encyclopedia w/pictures, but the plant in this picture is an oddity. Anyone have any idea what it is? Thick stems, spiky leaves, about 2-3 ft tall, spreads like crazy. I pried one of the blooms open, and its waxy and orange on the inside. Please help!
