Hi there! I'm trying to identify a plant that my brother and I inherited from my mother after she passed away. All I know if that it's VERY hardy and favours underwatering. My mother did not have a green thumb and she had this plant for as long as can remember without ever repotting it! I want to ensure it stays alive (repot it, feed it, etc.) and perhaps take a cutting from it. I would love your help identifying it! Thank you in advance...
