No data. The only known fact is that it is not a Pinguicula moranensis. More information will be certainly available later.


No data. According to the name, it is likely that this Pinguicula could come from the surrounding of the Sierra de Pachuca, from Mexico, state of Hidalgowhere is situated the  National Park of El Chico.

El Chico National Park is located on the eastern side of the Sierra de Pachuca mountains and ranges in altitude from 2,320 meters to a height of 3,090 meters above sea level. In 1898 it became the first national park decreed a natural reserve. The park covers an area of 2,739 hectares and is popular with hikers, mountain bikers and rock-climbers who come to scale its rocky peaks, including "La Ventana", the highest point in the park, just outside of Mineral del Chico.

Introduction in culture :

I found this plant in J.J. LABAT's collection (manager of the famous French Nursery "Nature et Paysage").


(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.


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

Flowering period : 


Multiplication : I have succeeded once up to now in pollinating the flowers of this Pinguicula. The plants can be propagated 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 particularly with it's white base as the new plantlets will sprout from this area. Don't try with the summer leaves, it is harder.

In full sun, the summer rosette of the Pinguicula from Pachuca can turn yellowish instead of green. You can note also that the plant can produce many flowers.
