This species was found and collected in the winter 1972, in Chiapas Mexico, by the Dr. A.J. Sharp from the university of Tenessee, Knoxville.

Althought Pinguicula sharpii is similar to P. lilacina, its morphological characters are quantitatively smaller than those of P. lilacina.


Type : From Mexico, Chiapas : on a moist and shaded bank along a road at Yerba Buena near Pueblo Nuevo.

Introduction in culture :

Dr. A.J.Sharp sent the collected plants to Mr. T. Kondo, the junior author's father and well known grower of carnivorous plants. Mr. T. Kondo rapidly popagated this new tiny Pinguicula by sexual reproduction and dispesed its offsprings to many horticulturist and amateurs around the world. 


There is no really doubts taht we are growng the heir of these first generation. 


This is again a proof is necessary that propagated and sharing our plants are the only way to insure their long time being in culture.

Life cycle : This species is annual or biennial and the seeds of the previous year reaches maturity in a few months.   


Media : Many media seems to work from calcareous soil to live Sphagnum moss. I get my best results in Sphagnum moss. This year, I  am trying a mix of 50 % vermiculite, 30 % opening media (volcanic rock and aqualite), 10% organic media from garden center and 10% sand.

You may ask why I am not trying again Spagnum moss : only because I forgot this year to prepare it before sowing the seeds and with the hot days, this media can rot very fast.


Pot : Various.


Cultivation : Nothing in particular : just sow the seeds on a wet media. The germination should occure within 4-5 weeks with high humidity. When the plants are aged of few more weeks, they can be grown in lower humidity. Remimber that this tiny species grow naturally on a moist and shaded bank so a shaded area is better than full sun ! 


Multiplication : Very easy by seeds. Flowers (self pollinisation) are produced at the end of the growing season before the death of the plant. P. sharpii is an annual or biennial species.
