Pinguicula macrophylla is a rather unusual species of butterwort native to Guanajuato, Mexico. It produces large oval carnivorous leaves at the end of long stalks (petioles) in the summer and during winter, grows a bulb-like bud of dormant leaves. Pinguicula macrophylla prefers a well draining mineral-based substrate and partially shaded conditions.
