ORIGIN AND HISTORY :

P. elizabethiae was discovered in 1990 during the investigations on the ecological impact of the future building of the Zimapan dam on the Moctezuma canyon. For memory, this is also during the same investigations that was discovered Pinguicula moctezumae.

These plants were identificated as P. cyclosecta according to Casper. The author of the publication compared this species with the related ones : P. colimensis and P. cyclosecta and finally noted that it was a new species.

Localisation / Map: 

- Pinguicula elizabethiae can be found in the canyon of the Rio Moctezuma, state of Hidalgo.

- In Queretaro state (Rio Moctezumae is the frontier between Queretaro state and Hidalgo State), around the road of San Joaquin, Municipality of Cadereyta.

HABITAT:  

P. elizabethiae grows on mosses, with Selaginella lepidophylla, Notholaena sp. and Cheilanthes sp. with a vegetation of matorral submontano. At altitudes between 1000 to 1600m.

P. elizabethiae grows on very inclined slopes of "rocas lutitas calcareas" that are, indeed, sedimentary rock composed largely of clay particles of varying sizes.

Introduction in culture :

This species has just entered culture in Germany...More soon.

CULTURE AND MULTIPLICATION : 

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

Life cycle : The life cycle observed 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. 

 

Media : I will 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 20cm, height 12cm for forming a colony.

 

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.
