ORIGIN AND HISTORY :

 

The type specimen of this species was collected near Guadalcazar in the Mexican state of San Luis Potosi by Mrs Renate Ehlers in 1979. 

 

The plant was introduced and grown in the botanical garden of Linz where F. Speta and F. Fuchs published it under the name Pinguicula ehlersiae. 

 

It is easy to understand the etymology of the name.

HABITAT:         

No data on the type specimen habitat was published but P. ehlersiae can be found at altitude betwenn 1200 to 1650 m on gypsum substratum. More soon on a postcard of Fernando Rivadavia.

Introduction in culture :

This species can be easily found worldwide in many carnivorous plants collections and carnivorous plants nurseries. 

CULTURE AND MULTIPLICATION : 

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

Life cycle : The life cycle observed in culture for this Pinguicula consists of two seasons, one wet and the other dry (see link). The plant forms different leaf rosettes according to the season. During the resting months (winter) the small succulent rosette is composed of numerous non-carnivorous leaves. The carnivorous leaves are produced in spring and during all summer. The life cycle of the plant is probably similar in it's native habitat but I have no data.

 

Media : I use a 100 % mineral media : 2 perlite, 2 vermiculite, 1 small sand (for aquarium), 1 fine white sand, 1 pouzzolane (volcanic lava), 1 aqualit (expansed ceramic for aquarium). The aqualit can be replaced by 1 of pouzzolane. Plants in this media grow slower but have a stronger root system.

 

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

 

Cultivation : I think that a slightly airy situation inside the greenhouse is important to avoid air stagnation. For this reason, I use a fan 24h/24h all the year round.

Watering is very important : from May to September (summer). I let the media drying slightly between two watering. I use rain water poured on the top of the pot taking care not to wet the rosette.  From October to April, It is important to let the media drying completely (no watering) but with an atmospheric humidity of about 80%. 

The mentioned months are indicative and can change according to your own growing conditions. In fact, when this Pinguicula begins to produce its non-carnivorous leaves, you have to stop watering and let the pot drying out completely. Inversely, when the plant begins to produce in early spring its carnivorous leaves, you have to progressively start watering again the pot.

Temperatures : during growth period, day temperatures are about 25°C but may reach 35°C when the sun is shining on the greenhouse in spite of the use of shading covers. Night temperatures are around 20°C. During resting period : day/night over freezing point. Lower temperature observed : - 4°C. I use an electronic petroleum heater to provide heat.  

 

Multiplication : I have succeeded once in pollinating the flowers of this Pinguicula but the seeds didn't germinate. The plants can be propagated  very easily using non-carnivorous leaves separated from the rosette  at the end of winter. You only have to carefully tear out the totality of the leaf including the white base as the plantlets will sprout from this area. Summer leaves can be used too.
