Violet butterwort’s solitary bloom may be pale violet to nearly white with five notched petals. The corolla is slightly tubular with a deep violet throat and violet veination. It is borne on an erect leafless scape that arises from a basal rosette of succulent yellowish-green leaves. Leaf margins are entire and involute. The scape, sepals and leaves are covered in tiny hairs. The hairs on the leaf surface secrete a sticky mucilage in which insects become trapped. (Insects often mistake the mucilage for drops of water.) Enzymes are then secreted to help the plant digest the insects. The ability to trap and digest insects allows violet butterwort (like most insectivorous plants) to survive in nutrient-deficient conditions. Subsequently, it helps prevent insect predation.
The genus name, Pinguicula, comes from the Latin pinguis, which means “fat” and alludes to the greasy feeling of the leaf surface. The species epithet, ionantha, references the Latin word ianthinus, or “violet.”

Soil: Moist to inundated, acidic soils with poor nutrients
Growth habit: About 6” tall
Garden tips:Although not commercially available, violet butterwort can be propagated by seed. Getting seed, however, may be challenging as it cannot be collected from public natural lands. Your best bet is to find someone who has it growing on privately owned land. Be sure to get permission before collecting on private land.
