Is there hope after Phal. crown rot ?

[euplusia]

This plant was bought in a DIY superstore and used for decoration in a south Americans vendor's booth during a sales expo. Due to wrong watering it developed crown rot and was given into my hands. Only one leaf and a flower spike were left over, roots were intact.
I took it for the challenge and cut off the spike to save the plant's energy. Placed it on a windowsill next to my other Phals where it received regular care with reduced watering and fertilizing (because metabolism and evaporation are reduced).
After 9 months a new plantlet at the plant's base between roots and leaf was formed and grew rapidly. The old leaf was shed, new roots were formed. I avoided repotting so far.
This is how the plant looks after 2 and a half years. A commercial grower produces a plant like this from a deflasked seedling in maybe 9 months. This hybrid is sold by thousands for a cheap price in order to attract customers to the DIY stores.
For the hobbyist doctors here it may be encouragement and hope when dealing with crown rot.
