It doesn't have any sharp points! The leaves are strappy and soft. After Hetty's ID, I Googled it and found that it's a xeriscape plant and can get huge. I'm not going to risk putting outside just yet. My little hoop house off the patio is absolutely full, so it'll have to go into the one along the fence. It's in my breakfast room that connects to the kitchen. It was one of the last plants I grabbed when the first freeze hit. I just thought I'd place it somewhere else after the freeze was over. With the Holidays came shopping, article writing, and other obligations. This thing just kept growing, even though I forgot to water it. Nearly overnight, it took a turn for the worse and starting turning brown.
