ORIGIN AND HISTORY :

- soon - 

 

A population of Pinguicula vallisneriifolia, far from the Sierra area was found in the "Hoz de Beteta" location near Madrid and mentioned in Casper. It was later published under the name Pinguicula dertosensis (- more soon -). 

Localisation / Map: 

From Spain, Prov. de Jaen. This is a natural Parc made of many Sierra. The most important is the Sierra de Segura. The Sierra de Cazorla or de Las Villas are smaller. 

 

Jurg Steiger told me that he found 74 populations of Pinguicula vallisneriifolia in the Sierra area, all with little differences.

HABITAT:  

Grows on vertical limestone rock walls, below overhanging rock parts in niches protected from direct rainfall. The plants in some locations grow near falls and are in very wet area.

Introduction in culture :

I grow differents clones from seeds and from carnivorous plants nurseries :

- Sierra de Segura, Cerrada de Elias, Rio Borosa. At this site the flowers are almost white and the corolla lobes are less overlapping than in the Cazorla site.

- Sierra de Las Villas. This is the northern site of this species.

- La Iruela, Sierra de Cazorla. This is the most vividly coloured of the locations of this species. The wide corolla lobes are overlapping. 

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 in summer and the stolons. After flowering Pinguicula vallisneriifolia forms the long-leaved summer rosette. Pinguicula vallisneriifolia has also digestive glands on the underside of the leaves as for P. longifolia subsp. longifolia. 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 a 100 % mineral media : 2 perlite, 2 vermiculite, 1 small sand (for aquarium), 1 fine white sand, 1 pouzzolane (volcanic lava), 2 marly calcareous detritus. 

Pot : plastic, colour terracotta, diameter 12.5cm, height 12cm.

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.

 

Multiplication : By seeds or using the gemmae produced around winter hibernacula. You can also leave the plant producing its runners naturally.

PICTURES: (click to enlarge)

Serge Lavayssiere went in the Sierra area in august 1994. The plants had finished flowering but the long leaves were present. We went all three, Jean-Rémi Fierfor, Serge Lavayssiere and Eric Partrat in April 2003 but it was too early to have the flowers unfortunately. The flowering is in late may of June in our opinion. We will show you below the two periods.

Sierra de Cazorla : la Iruela

According to many people, Pinguicula vallisneriifolia from "La Iruela", in the Sierra de Cazorla is the most vividly coloured of the locations of this species. This is on limestone at altitude of 1200m.

Sierra de Segura : Cerrada de Elias, Rio Borosa

"At this site the flowers are almost white and the corolla lobes are less overlapping than in the Cazorla site" (Jurg Steiger in ICPS database, April 16, 1973). This is also on limestone, in a gorge, at altitude of 900m.

Sierra de Las Villas :

Serge Lavayssiere found only two flowers in this location as it was late august 1994 and then too late for the flowering time. Both flowers were white with yellow heart. We all thought for many years (10) that this location had only white flowers but the flowers bulbs we saw there in April 2003 were "unfortunately" colored.
