Small butterwort (Pinguicula pumila) is a diminutive, insectivorous wildflower found in wet pinelands and prairies throughout most of Florida. It blooms winter through spring.
Small butterwort has solitary blooms that vary in color from pale violet to pink to nearly white (rarely pale yellow). It typically measures no more than 1 inch across. The corolla is funnel-shaped with five petal-like lobes, each notched at the top and occasionally with noticeable venation on the lobe surface. The corolla tube may be purple or yellow with reddish striations. The base of the corolla is spurred and reddish. Flowers are born on erect leafless scapes that arise from basal rosettes of succulent yellowish-green leaves. Leaf margins are entire and involute. The scape, sepals and leaves are covered in tiny glandular hairs. Seeds are born in inconspicuous capsules.

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 Small 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, meaning “fat.” It alludes to the viscous or greasy feeling of the leaf surface. The species epithet pumila is from the Latin pumilus, or “dwarf.”

Carnivorous plants have very specific habitat requirements and as such are not suited for use in urban native plant gardens. However, many Florida native carnivorous plants can be purchased from online retailers. Always be certain that retailers are certified by their state agriculture department, who inspect and ensure proper origin of plants.
