I really don't know. A few decades, certainly. I bought it from someone who bought an entire collection a little neglected because the former owner was no longer able to take care of it. This plant is a little smaller nowadays but most of the tissue affected by the pests has already been replaced by new growth.

Wow awesome, I would like to have a specimen like this! I just have a 3 year old, maybe 3-4cm diameter. ^^

@@projet2684 I understand that perfectly, they grow so slowly... I only got this one because it was at a good price for a plant of this size. Due to the scars he had, of course.
