Just like my P. planifolia I grow my P. lutea outside all year with sun during the morning and shade in the afternoon. They are grown with the tray method. I tried undrained pots previously but they succumb to rot easily. P. lutea can tolerate somewhat drier conditions in the wild than some other Pinguicula.
Pinguicula lutea flower "sleeping" at night. This movement is called nyctinasty.

A side view showing Pinguicula lutea's spur. It looks like a bee could fit perfectly in there.
It is really starting to feel like spring!
