Mexican Butterworts – Pinguicula

The latest arrivals to the tropical greenhouse are a set of Pinguicula species originating in Mexico and some hybrids and cultivars derived from them. These add to the plants of Pinguicula laueana we have been growing there for the past 6 months.  This kind donation from Dianne Riddiford of the Carnivorous Plant Society will allow some interesting new ideas to be taught.  These add to the Pinguicula laueana donated by William Purvis in 2012 when we were first setting up the greenhouse.

The Mexican Pinguicula species are a monophyletic group (all come from a single evolutionary origin) and have diversified in habitats that are not just unusual for Pinguicula but also for carnivorous plants in general.  They are quite succulent and fleshy plants that form a tight rosette of overwintering leaves that can survive very dry conditions.  Some have even been seen growing side by side with cacti.  The weather in Southern Mexico, where these plants grow is warm throughout the year but the rainfall is highly seasonal.

Grow list

Species: Pinguicula agnata, Pinguicula ehlersiae (Santa Catarina), Pinguicula ehlersiae (Ixmiquilpan, Hidalgo, Mexico), Pinguicula esseriana, Pinguicula laueana, Pinguicula moranensis
Hybrids: Pinguicula laueana x P. emarginata, Pinguicula gigantea x P. moctezumae
Cultivar: Pinguicula ‘Aphrodite’

The curious brick red colour of the compost is beacuse I’m using a mix of 5 parts Seramis to one part sand/loam mix.  This is providing a combination of moisture and free drainage needed fro these plants.
