ORIGIN AND HISTORY :
The plant was discovered in 1910 by Shafer and described 10 years later by Barnh and originated from the region of Moa-Baracoa.
The region of Moa-Baracoa, is the most important area for the vegetal endemism in Cuba, and probably in all the Caribbean area, with 967 taxa endemic, of which 365 can be seen in that area.
It is impressive to note that, directly or indirectly, the greater floristics relations of all the regions of Eastern Cuba are in Moa-Baracoa.
These evidences demonstrate that the flora of this zone has played an important role in the formation of the other local floras of the Eastern of Cuba.

Pinguicula benedicta is growing on the river's steep and rocky banks of the fast running Rio Jaguani as stated in IPSG Vol. 10, 2000 by Paul Temple.
" ... some 1 metre above the river and spreading over a band some 1 metre wide, a mass of P. benedicta plants could be found spreading for at least several hundred yards".
"At first sight there would appear to be no threat to this type of location. However, the moutain air would present the greatest threat. The east of Cuba is an important mining area, particularly for Nickel but also for other minerals. The factories working with the raw ores produce thick smoke that pollutes the air causing acid rain. There was no evidence that this was causing a problem to Pinguicula benedicta but any damage to the surrounding forest could be disastrous. Direct mining seems unlikely to be an immediate risk as plenty of areas present easier targets than rivers and river banks, but should communism end or relax in Cuba, the consequential influx of US dollars and business could rapidly change this view. Similarly, the use of timber is not currently a direct threat but political changes could see this change too. Happily, the Cuban government is a good example of a government willing to apply pragmatic conservation plans to sensitive areas as evidenced by the large number and size of conservations areas in Cuba. " Paul Temple in IPSG, Vol. 10, 2000.
Introduction in culture :
It seems that this species may be (or was) in culture in Europe. No more informations are known.
CULTURE AND MULTIPLICATION :
P. benedicta is a plant of high altitude, requiring much humidity and damp soil according to the observation Paul Temple did during his discovery of P. benedicta along the Rio Jaguani.
A culture on wet peat moss should work.
Paul Temple added the following information (personal communication on 24th february) :
" I believe that P. benedicta may be very difficult to grow successfully. Not much is known about it. In the wild it grows on almost pure laterite soil (poisonous to most plants)." Paul Temple.
This rare component can be purchased in few aquariums center like here :
