Pinguicula filifolia grows in full sun to light shade in a mild soil alkalinity ranging between 7.6 and 7.8. Filifolia thrives in wet soil and flourishes in white sand savannahs and warm temperatures around 30 degrees celsius. The plant prefers high levels of humidity, up to 70%, and experiences much of its growth in the rainy seasons that last between May and November. In addition the plant must tolerate a dry season that lasts between November and April. They maintain a tropical growth rate and thrive near other endemic species due to the partial shade.
