ORIGIN AND HISTORY :

 

Pinguicula nevadensis is an endemism of the alpine zone of the Sierra Nevada in southern Spain.  

Localisation / Map: 

From Spain, Sierra Nevada and Sierra de Alfacar.

HABITAT:  

Pinguicula nevadensis is exposed to very intensive sun radiation in habitat but its leaves remains only slighty reddish colored. The plants can be found near sunny springy slopes and alpine lake. It grows on silicate granite ground. As the species occured at altitudes between 2160 to 3100 m, snow covered the plants for 5 to 7 months !. There are also frequent fog.

Casper publication, add the following species that occured with Pinguicula nevadensis : Carex intricata, Gentiana alpina, Gentiana sierrae, Ranunculus acetosellifolius and Ranunculus angustifolius-uniflorus.

 

Temperatures and  CLIMAT :

 

- Average temperature for a year : 6C

 

- January : max. : 2C - min.: -10C

- August :  max. : 14C - min.: 0C

 

- Some ponds can 

- Nearly no rains in July or August

- Rains in May to June and September to October

 

- Snow remains on ground from October to May, and sometimes until June.

 

- Some ponds can still be frozen until june.

Introduction in culture :

I grow some young plants from french carnivorous plants nursery, Nature et Paysages.

CULTURE AND MULTIPLICATION : 

(North hemisphere, France near Paris, in a garden - see the map -)    

 

Life cycle : In spring, the cycle begins by the opening of the winter buds and the production of the first carnivorous leaves. The first leaves are followed by the flowers. New carnivorous leaves are produced during all the season. Near autumn, or earlier, if your conditions are not optimal, the next hibernacula is revealed in the centre of the rosette. Then leaf production stops and the old leaves decay slowly. The plant (reduced now to a small hibernacula) is ready for winter and for the next cycle. 

 

Media : I use the following media : 1 peat, 1 vermiculite, 1 sand (all size). 

Pot : In big box, with direct sun for more than 8 hours per day.

Cultivation :  The long term cultivation of temperate Pinguicula is difficult : If the summer growing conditions are not optimal, the plants will form very weak hibernacula which easily rot. 

Optimal summer growing conditions are : good air humidity, cool temperature and UV lights.This species need a good amount of good sun to grow.

 

Multiplication : By seeds or using the gemmae produced around winter hibernacula.
