my name is Igor and I have a house plant that I have been trying to ID for a number of days. I started it from cuttings from another plant and placed them in a vial of water for a few weeks until it made a large enough root system. I then planted it in a rich loamy soil and after a few years it has really taken off. The original plant I started it from was my Grandmothers, and she had planted nearly 45 years ago. She has always called it an Elkhorn Cactus but, when I went online to read a little more about them I couldn’t find any that resembled the plant I have. Hopefully you’ll be able to help me.
