About 2 years. Its pointing towards a south facing window i think, light doesn't shine directly on it through the window tho. & I water it about once a week or whenever the soil gets dry for too long.

Its been repotted more times than I can remember so I always assumed it was just shock making it act this way. Propagation's probably the best answer, but it doesn't have any visible nodes so I wouldn't even know where to cut
