Description
This listing is sold as Pinguicula primuliflora, a butterwort. Like other Carnivorous Plants, they are sold in our Carnivorous Plants collection. They are not all one genus. Venus flytraps belong to the sundew family (Droseraceae). Tropical pitcher plants (Nepenthes) belong to the Nepenthaceae. Sundews are also in Droseraceae. Hardy North American pitcher plants (Sarracenia) belong to the Sarraceniaceae, and butterworts (Pinguicula) belong to the bladderwort family (Lentibulariaceae).
What it is: This listing is sold as Pinguicula primuliflora, a butterwort in the bladderwort family (Lentibulariaceae). We have not found a separate NC State Extension species page, so care and size follow the genus profile. This is a southeastern North American species; the genus profile notes that a dormancy period is needed to regrow and bloom in spring.
Light: Give it full sun to partial shade (NC State Extension). A grow bulb helps in our dark winters. In a container, use whole-fiber sphagnum moss, or equal parts peat moss or coir and coarse vermiculite or sharp sand (NC State Extension).
Watering & care: Keep the mix consistently moist; do not let it dry out (NC State Extension). Prefer rainwater or distilled water, as with other carnivorous plants.
Humidity: A humidifier helps in our dry indoor winter air.
Temperature: Treat it as a houseplant here. NC State Extension lists the genus in USDA zones 8 to 11, which is not a promise of outdoor winter survival in Alberta. Keep it off cold glass.
Winter indoors: NC State Extension, writing about the genus, says a dormancy period is necessary for plants to regrow and bloom each spring, and to cut back dead leaves in winter or early spring. Keep the mix moist, and give it a bright, cooler winter rest rather than a warm, dry one. A grow bulb can come back on as new growth resumes.
Expected indoor size: NC State Extension lists the genus at about 2 to 12 inches tall and 1 to 6 inches wide. We do not have a published size for this particular selection, so we are not guessing beyond that genus range. A potted plant is typically a small rosette.
Feeding: Do not use a regular houseplant fertilizer. Like other carnivorous plants in this collection, it is adapted to nutrient-poor soil and takes nutrients from small insects trapped on the leaves (NC State Extension).
Pets & pests: We do not have an ASPCA listing for butterworts, so we are not calling them pet-safe. It is still a plant, not a snack.
About your plant: Every plant is a little different. Size, fullness and leaf count vary from plant to plant and change with age and light, so we can't promise a particular trap or pitcher size, leaf count or colour. The options listed (2-1/2") refer to the pot or container size. They do not guarantee an exact trap or pitcher size, leaf count or colour. Photos show typical plants from our greenhouse, not the specific plant you will receive. The shared gallery image shows other Carnivorous Plants as inspiration. Our existing listing noted that this plant can help with fungus gnats, ants, fruit flies, house flies and spiders. These plants do trap small insects as food; that is not a promise they will clear a pest problem.
