Pinguicula vallisneriifolia white flower

Pinguicula vallisneriifolia is a superb pinguicula that thrives in limestone soil.
I personally prefer to keep it in the shade with the water level up to the leaves.
It’s a plant that stands the cold well in winter, but I prefer to keep it frost-free.
The white flower variety, on the other hand, doesn’t produce totally white flowers, but they are much lighter than the classic form.
The plant will be sent in a pot, currently in its resting form.
