Introduction in culture :

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. 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 media composed of sphagnum peat 50%, 10% vermiculite, 5% fine sand, 35% pouzzolane (volcanic lava). 

Pot : big plastic box.

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.

I grow my plants in my garden all the year with a good amount of direct sun.  

 

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