The Dwarf Butterwort, Pinguicula pumila, forms a small rosette about 1/2" to 1" across, made of pale green leaves with slightly rolled edges. It is similar in appearance to a miniature Yellow Butterwort. It is a short-lived (1-2 years), warm-temperate perennial. In cultivation, it is best treated as an annual, with the yearly collecting/sowing of seeds. It prefers moist, not wet, sandy peat soils, and open sunny conditions. It is often associated with P. caerulea and P. lutea, but not P. ionantha, P. planifolia or P. primuliflora which favor wetter habitats. It benefits from the dappled light provided by growing among grasses and other plants. It blooms mid Spring with small flowers that vary in color from yellow and white to purple. It rarely tolerates a light frost, preferring warmer winters. There is no winter bud. It has the widest distribution of any Pinguicula of the southeastern USA growing from coastal North Carolina throughm Texas, and the Bahamas. Though considered a perennial, it often dies soon after flowering. It can be continued by sowing its seeds, or extending its live by removing the flower stalk. It does not tolerate drying out. The Dwarf Butterwort is a curious addition to the carnivorous collection indoors or out. This selection comes from seed, and will show some natural variations.
