Okay, one more... I really dont kill EVERYTHING! I have great lucky with roses, ferns, ginger and everything else but my husband planted these and I feel like he planted them too deep. These are pictures are pictures of two Century plants we have in the same bed as the Mexican Palms.
Maybe too much water? Century plants are very cold hardy but like it dry. When in doubt, leave it alone. Mine grows in a pot at the front steps and only gets watered when it rains. Lately, that is not often enough for everything else. Red
