What it is: This listing is sold as a Mexican butterwort 'Weser' (Pinguicula) in the bladderwort family (Lentibulariaceae). NC State Extension describes butterworts as rosettes of greasy, sticky leaves that trap small insects. We have not found a published extension or Royal Horticultural Society profile for the 'Weser' selection, so size follows the genus. We are not assigning the temperate winter cut-back described for some butterworts to this Mexican listing.

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: Keep it in your brightest frost-free window or under a grow bulb, and do not let the mix dry out.

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.
