Butterwort Plant Information

Butterwort showcases an astonishing range of sizes, colors, and shapes that make them stand out in any botanical collection. From diminutive one-inch plants to more substantial 18-inch specimens, Butterwort offers a visual feast of white, pink, maroon, green, and yellow hues.

Classifying under the Pinguicula genus within the Lentibulariaceae family, butterworts represent a group of plants encompassing over 80 species. Their natural habitats span various continents, excluding Australia and Antarctica.

Depending on their origin, Butterwort can be categorized as temperate, warm temperate, or tropical, each requiring specific care to ensure their successful growth. The Butterwort plant employs a fascinating insect-trapping strategy. Its leaves are covered in a glistening, sticky substance that lures insects. Once an insect lands on the leaves, they become ensnared in the adhesive secretions. The plant then gradually curls its leaf edges, encasing the prey and initiating the process of digestion.

Butterwort Plant Propagation


You can expand your Butterwort collection through two distinct propagation techniques: leaf pullings and offsets. By mastering these methods with the help of our guide, you can multiply your plants while enjoying the rewarding experience of nurturing new specimens.


  • Choose mature, undamaged leaves from the Butterwort plant for propagation.
  • Put the leaf on the preferred growing medium within a seed-starting tray.
  • Provide consistent lighting, moisture, and temperature levels akin to seed germination.
  • Over time, buds and roots will emerge, signaling successful propagation.
  • Once a second set of leaves develops, remove the humidity cover for continued growth.
  • After several months, transfer each cutting to its individual container for ongoing care.

Propagate Any Plant Cutting Quickly Using this Trick


  • During dormancy, identify clumping sprouts (offsets) on your Butterwort plant.
  • Carefully cut the offset or pups from the parent plant using a sterilized blade.
  • Position the offset with their pointed ends upward within the chosen growing medium.
  • Maintain warm and humid conditions, allowing the offset to root and flourish.
  • Follow standard care practices, tailoring them to the needs of each species.

When to Plant Butterwort

Timing is crucial when it comes to planting Butterwort as it ensures their robust growth and flourishing health.

Requirements for Growing Butterwort Plants



Butterwort thrives in bright, indirect light. Place them in a location that receives filtered sunlight, such as near east or west-facing windows.

If you’re growing Butterwort indoors, consider using artificial grow lights with a spectrum suitable for plant growth. Avoid exposing them to intense, direct sunlight, as it can scorch their leaves.


Selecting the right soil mix is vital for Butterwort growth. You can either buy a commercial soil mix particularly made for carnivorous plants or prepare one yourself.

A recommended mix includes a combination of peat moss, or coco coir, perlite, and sand. This mixture ensures proper drainage and aeration for the plant’s root system. Here are some of the best homemade soil and potting mixes suitable for Butterwort plants:

1. Peat and Sand Mix

  • 1 part peat moss (sphagnum) or coco coir
  • 1 part silica sand (washed and free of minerals)

This mix offers good aeration and retains moisture without becoming waterlogged. The lack of nutrients in the sand complements the nutrient-poor nature of peat, making this mix suitable for Butterwort plants.

2. Peat and Perlite Mix

  • 1 part peat moss or coco coir
  • 1 part perlite

Perlite adds excellent drainage and aeration to the peat, helping to avoid root rot. It’s essential to ensure that the perlite is free from added fertilizers.

3. Pure Long-Fibered Sphagnum Moss

  • 100% long-fibered sphagnum moss

Long-fibered sphagnum moss provides excellent moisture retention while still allowing air to the roots. It’s often used alone for Butterwort plants.

4. Peat, Sand, and Perlite Mix

  • 1 part peat moss or coco coir
  • 1 part silica sand
  • 1 part perlite

This mix combines the benefits of both sand and perlite with peat moss, ensuring good aeration, drainage, and moisture retention.

Important Considerations

  • Avoid Garden Soil and Compost: These typically contain too many nutrients and may have a pH that’s not suitable for Butterwort plants.
  • Water Quality: Always use distilled water, rainwater, or reverse osmosis water when moistening the soil mix, as tap water may contain harmful minerals.
  • Potting Container: Choose a container with drainage holes to prevent waterlogging.
  • Acidity: Butterwort plants prefer slightly acidic soil. If possible, test the pH to ensure it’s around 5.0 to 6.0.


Proper watering practices are crucial to prevent water-related issues such as root rot. Water your Butterwort from the bottom by placing the pots in a saucer of filtered or rainwater.

This method prevents minerals and salts from accumulating on the leaves, which can damage sensitive surfaces.

Keep the soil consistently moist, but avoid waterlogging and allow the top inch of the soil to dry slightly before watering again.

Temperature and Humidity

Maintaining suitable temperatures is essential for Butterwort growth and health. Aim for a temperature range of 60 to 85°F (15 to 29°C) during the active growing season.

It’s crucial to avoid prolonged exposure to temperatures below 50°F (10°C) as it can hinder their growth. Butterwort becomes stressed and less active when subjected to temperatures exceeding 90°F (32°C), and it can disrupt their natural processes and cause wilting, so a balance in temperature is a must.

High humidity levels benefit Butterwort as it mimics their natural habitats. If you’re growing butterworts indoors, consider using a humidity tray filled with water or placing a small humidifier nearby.

This ensures that the plants receive the moisture they need, which is especially important for their carnivorous mechanisms to function effectively.
