Can confirm that if you have a group of stalks that start to yellow, put them in a sunnier location and they will green up again. They also love a bathroom for the humidity. Didn't know new plants could be rooted from clippings - I'll try that. I grow mine in water exclusively, with gravel or stones. While it's easy to change water every couple weeks, the roots get extremely bundled up in gravel once they get older and it's not feasible to clean the substrate. You'd have to replace it every time, so just replacing the water is usually enough. I don't mind some algae in a clear container but I keep them in all sorts of different pots, some clear, some not. Often, if one stalk yellows suddenly, the entire group will die fast thereafter. I've had many groups that live for several years, yet others don't make it more than a year. But since they are inexpensive, I just replace as needed.
