Introduction in culture :

- Not yet - 

CULTURE AND MULTIPLICATION : 

I would grow instinctively P. involuta like P. lusitanica.

According to the altitude, this species should be grown more as a "temperate" species than as a "tropical" species.

The red coloration can be a result of a high sun exposure.
