Probably 6 years old or so.
Rescue from a neighboring business that kept it under next-to-dark-conditions in 8" of water a couple years ago (my guess at least, it was in an un-drained planter and the mineral stains go that far up the exterior of the plastic pot).
I got about 6 happy new plants after I adopted it.
It's still in the original soil with top dressings over the years.
Trying to decide whether to keep it as is, re-pot, up-pot, or just dump it out and break it up and take cuttings from what I can't divide. Just getting it out will be a chore so I have no clue what the roots looks like, but regardless of what I do I think it wants new soil.
A friend just gave me a dozen 2 gallon pots, so I'm leaning towards breaking it up and seeing what there is to work with.
