Because I was given the plant as a gift, and I can't stand to throw good plants away.
I think it is a fine plant, but I have read mixed results on it. Some say it is aquatic, some say it is not. I think it is a great looking plant. my LFS just got some more in that look even better than the ones I got, wish I could swith out. I think they look nice.
Mine is neither growing or rotting right now. Although I swear I have one new growth on one of them, but as soon as I noticed it, it stopped LOL.
