Pinguicula 'Pirouette' is a hybrid produced by Leo Song.  Technically it is Pinguicula agnata X (moranensis X ehlersiae).  Under certain light conditions it produces very pink leaves.  If you want to have plants like this you will need fluorescent lights with a high red component.  Standard "kitchen and bath" fluorescent bulbs that try to match the spectrum of incandecent bulbs work well.  Under these conditions, P. agnata and P. ehlersiae will also be pinker than "normal".
