Description (In Casper)Permalink

(See description of Pinguicula grandiflora)

Differt a typo calycis superioris labii lobis obtusis, subaeque longis ac latis; corolla plus minusve rosea vel pallide-lilacina, corollae lobis brevioribus; fauce violacea vel pallide violacea-pilosa; calcari recto, subulato, acuto, breviore.

Chromosomata 2n=32

Origin and HistoryPermalink

This endemic species has all the characteristics of Pinguicula grandiflora. But the spur and the flowers are smaller, the spur is also purple. The colour of the flower differs also (see pictures below), pale pink for the corolla with nice purple strips in the throat. The corolla margin seems to be often more undulated than in the normal form according to J. Steiger.

Location / MapPermalink

Pinguicula grandiflora subsp.rosea is a species endemic of the calcareous mountains around Grenoble.

HabitatPermalink

Shady and half shady mossy places on slopes or in dripping limestone walls

Introduction to HorticulturePermalink

No data, my plants comes from seeds labelled from the place described below.

Growth and PropagationPermalink

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

Life CyclePermalink

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.

MediaPermalink

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.

PotPermalink

In small box, with direct sun for 5 hours per day.

CultivationPermalink

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.

PropagationPermalink

By seeds or using the gemmae produced in great number around winter hibernacula.
