Butterwort (Pinguicula) Care Guide

Butterworts (Pinguicula) catch gnats and small insects on sticky, greasy leaves. Mexican butterworts are colorful, compact, and forgiving, and they make excellent natural fungus gnat control. Their needs differ from bog plants in a few important ways, especially when it comes to soil and winter watering.

Types of butterworts

• Mexican butterworts are the most popular group. They grow carnivorous summer leaves and many form a smaller, succulent rosette in winter. All of the butterworts we sell are Mexican species and hybrids.
• Temperate butterworts from colder climates form tight winter buds called hibernacula and need a cold dormancy.
• Warm-temperate butterworts from the southeastern United States grow in wetter, bog-like conditions.

Water

Use only distilled, reverse osmosis, or rain water. Keep the soil lightly moist during active growth, and let the tray dry slightly between waterings rather than leaving plants sitting in water constantly. Reduce watering during the winter succulent phase.

Light

Bright, indirect light. A sunny windowsill or grow lights are ideal. Too little light leads to pale leaves and stunted growth, while strong light brings out the pink, red, and purple coloring many hybrids are known for.

Soil

Mexican species prefer airy, mineral-based mixes: sand, perlite, vermiculite, pumice, or crushed lava rock with a little peat. Low-organic, rocky soil prevents rot during the drier winter phase. Our Ping Soil Mix is made for Mexican pings. Temperate species prefer a wetter peat and sand mix.

Winter succulent phase

Many Mexican species form small, succulent leaves in winter as days get shorter. At that stage, reduce watering so the soil barely dries between waterings, and stop setting the pot in standing water. Keep them in bright light. The plants look smaller and less sticky during this time, which is normal. Larger carnivorous leaves return in spring.

Propagating from leaf pullings

Mexican butterworts are easy to propagate from leaves:

1. Choose a healthy, mature leaf from the base of the rosette.
2. Gently pull it sideways so it comes away cleanly with the white base intact.
3. Lay the leaf flat on moist, mineral-based mix, such as our Ping Soil Mix.
4. Keep it bright and humid, such as under a clear cover, but not soggy.
5. Small plantlets usually form at the base of the leaf within a few weeks.

Flowering

Butterworts produce showy, violet-like flowers on tall stalks, often in spring. Flowering doesn't harm healthy plants, and the flowers are one of the best reasons to grow them.

Containers and ping gardens

Plastic pots with good drainage are a solid choice. Many growers build ping gardens: wide, shallow containers planted with several Pinguicula together and topped with lava rock or moss. This makes watering easy, looks natural, and raises humidity around the plants. Pings also adapt well to terrariums and open dish gardens, as long as there is airflow and the soil doesn't stay stagnant.

FAQ

Do butterworts get rid of fungus gnats?

Yes. Their sticky leaves are one of the most effective natural fungus gnat traps you can grow, which is why many houseplant collectors keep a few pings near their other plants.

Why is my butterwort shrinking in winter?

Many Mexican butterworts switch to a smaller, succulent winter rosette as days get shorter. This is normal. Water less during this phase and the larger carnivorous leaves return in spring.

Can I propagate butterworts from leaves?

Yes. Gently pull a healthy leaf from the base of a Mexican ping and lay it on moist, mineral-based mix. Small plantlets usually form at the base of the leaf within a few weeks.

Should butterworts sit in a tray of water?

Not constantly. Mexican butterworts rot if they stay waterlogged, especially in winter. Let the tray dry out slightly between waterings.
