Thank you,
@Stush2019. That is so strange. I appreciate your advice too, to cultivate it as a "tree" and I look forward to seeing what it looks like in a year or so. I am learning to like it - this strange, mutant thing in my house - only because it's rare and different. I am not so crazy about its appearance, but it may end up being more attractive when it has leaves coming out of the top. Thank you for sharing your knowledge, and many thanks for your words of encouragement!
