Growing Mexican
Pinguicula
Everything you need to keep your butterworts (that's the common name for Pinguicula) thriving. Light, water, dormancy, and what to do when your plant arrives.
Light
Bright and indirect. No harsh midday sun.
Water
Distilled or rainwater only, when the mix feels dry.
Soil
Our soil blend, or peat moss and perlite. Never potting soil.
Humidity
Normal household air is fine.
Winter
The plant shrinks and rests. Water far less.
Before Your Plant Arrives
Plants ship bare-root, so a few inexpensive supplies make arrival day easy. Everything here is available at any hardware store or garden center.
What to Have Ready
- A small pot — 2 to 3 inches wide with a drainage hole. Plastic or terracotta both work.
- A fast-draining mix — grab a bag of our Canyon Exotics soil, or make your own with a 1:1 blend of peat moss and perlite. Never regular potting soil.
- A jug of distilled water — about a dollar at any grocery store. Tap water harms these plants over time.
- A bright spot — an east-facing windowsill, or anywhere with bright, indirect light.
Nice to Have
- A clear plastic cup — flipped over the plant, it makes a simple humidity dome for the first week.
- A small grow light — only needed if your home doesn't have a bright window.
Unpacking & Acclimation
Your plant just traveled through the mail. A little extra care during the first few days goes a long way.
Unpacking
Open your package as soon as it arrives. Each plant ships in a small cup with damp paper towels to keep it stable and hydrated during transit. Carefully remove the plant from the cup and paper towels.
Potting Up
Pot it into your prepared mix right away (see Soil & Potting). Give it a light watering with distilled water to settle the roots. Keep the mix loose and airy, don't pack it down.
Acclimation
Place in bright indirect light at first, then slowly accustom it to more light. A little extra humidity helps recovery. A clear plastic cup flipped over the plant works as a simple humidity dome.
What's Normal
Some leaf wilting or minor browning in the first week is just transit stress. The plant will bounce back as new leaves come in from the center of the rosette.
Ordered in Fall or Winter?
Your plant may arrive in its compact winter form: small, tight leaves that aren't sticky. That's a healthy resting plant, not a damaged one. Pot it up as usual and sticky spring leaves will follow.
Light Requirements
Mexican Pinguicula do best in bright, indirect light. Direct sun will scorch the leaves, so filtered light or a shaded windowsill is the way to go.
Indoor Growing
An east-facing window works great. South or west windows are fine too if you add a sheer curtain or set the plant back a couple feet from the glass. Grow lights on a 12 to 14 hour cycle also work well year-round.
How do I know if it's getting too much or too little light?
Too much light shows as bleached or reddened leaves, curling edges, or dry crispy tips — if you see any of this, move the plant to a shadier spot. Too little light shows as elongated, pale leaves reaching toward the light source, and you may also notice less dew on the leaf surfaces.
Watering Guide
Pinguicula are not bog plants. Unlike most carnivorous plants, they actually prefer to dry out a bit between waterings. Think more succulent, less swamp.
How much and how often should I water my Pinguicula?
Never use tap water — use distilled water (a gallon jug from any grocery store works), reverse osmosis water, or rainwater. The minerals in tap water build up in the mix and slowly damage the roots. During active growth (spring through fall), water when the top of the mix feels dry: pour lightly from the top, or set the pot in a shallow tray of water for 15 to 30 minutes and then drain. Don't let the pot sit in standing water for long. In winter, water far less — overwatering a resting plant is the easiest way to lose one. The winter rosette (the plant's compact cold-season form) is basically a succulent, so a light watering every 10 to 14 days is usually plenty, or just water when the mix is fully dry.
Soil & Potting
In the wild, Mexican Pinguicula grow on limestone cliffs and mossy rocks. Their roots are tiny, so they need a fast-draining mix rather than rich soil.
Never Use Regular Potting Soil
Standard potting soil holds too much water and too many nutrients, and it will kill a Pinguicula. If you remember one thing from this section, make it this.
Recommended Mix
We pot every plant in our own Canyon Exotics soil, available in the shop. To make your own, use a 1:1 blend of peat moss and perlite.
Pot Selection
Small pots are all you need. A 2 to 3 inch pot is plenty for most species. Terracotta or unglazed ceramic pots wick moisture well. Plastic works fine too, just don't overwater.
Repotting
Repot every 1 to 2 years or when the mix starts to break down. Spring is the best time, right as the new carnivorous leaves start coming in. Be gentle with the roots.
Humidity & Airflow
Mexican Pinguicula handle lower humidity better than most carnivorous plants. They adapt well to typical indoor conditions and don't need anything extreme.
Ideal Range
40 to 70% relative humidity is the sweet spot. If your home runs dry, grouping plants together or setting them near a shallow water tray can help raise the humidity around them.
Terrariums & Enclosures
Open containers or partially enclosed terrariums work well. Avoid fully sealed setups. Stagnant air promotes rot and fungal issues, so some airflow is just as important as humidity.
Seasonal Dormancy
Mexican Pinguicula shift between two distinct leaf forms throughout the year (a rosette is just the circular cluster of leaves). Understanding this cycle is the key to not accidentally killing your plant during winter.
Summer Rosette (Carnivorous Phase)
Broad, sticky, dew-covered leaves that trap small insects. This is the active growing season. The plant is producing new leaves quickly and may flower.
Winter Rosette (Succulent Phase)
Tight, compact rosettes of small, non-carnivorous leaves. The plant is resting, not dead. Reduce water and stop feeding. This usually starts in late fall as days get shorter and temperatures drop.
Triggering the Transition
Shorter days and cooler nighttime temperatures (50 to 60°F) naturally trigger the shift. Indoor growers can simulate this by reducing light hours and moving plants to a cooler room.
Don't Panic
Outer leaves browning and dying back during the transition is completely normal. The plant is putting its energy into the new rosette form. Leave the dried leaves in place, they help protect the crown.
Feeding
Pinguicula catch their own food with sticky, glandular leaves. They don't need to be fed by hand.
How They Eat
The leaves produce a sticky dew that traps small insects like fungus gnats and fruit flies. Once caught, the leaf slowly digests the insect and absorbs the nutrients. If your plant is near a window or gets any air circulation, it's almost certainly catching enough food on its own.
During Dormancy
When the plant shifts to its winter rosette, the leaves are no longer sticky and it stops catching insects. This is normal. The plant doesn't need to eat during this phase.
