Overview
Pinguicula pumila Michx. is a carnivorous plant that belongs to the Lentibulariaceae family. It is commonly known as the Dwarf Butterwort.
Origin
Pinguicula pumila Michx. is native to North America, particularly in the eastern parts of Canada and the United States.
Description
The Dwarf Butterwort has rosettes of small leaves that are about 0.4 to 1.2 inches long. The leaves are glossy, green, and are covered with minute glands that secrete sticky mucilage. The mucilage traps small insects which are then digested by the plant. Pinguicula pumila Michx. produces delicate, pale blue to purplish flowers that bloom from May to August. The flowers are about 0.6 to 0.8 inches wide and have a distinct yellow patch on the lower lip.
Uses
Due to its insect-eating habit, Pinguicula pumila Michx. is considered a natural pest control option for small insects such as fruit flies and gnats. The plant is also cultivated for its ornamental value and is a popular addition to carnivorous plant collections.
Light Requirements
Pinguicula pumila Michx. requires a substantial amount of sunlight to grow and thrive. The plant should be exposed to direct sunlight for at least four hours a day. However, extreme heat and excessive sunlight can lead to wilting and damage, especially during the summer. As, in their natural habitat, the Pinguicula pumila Michx. survives in the full sun, they can harm when kept in low light conditions.
Temperature Requirements
Pinguicula pumila Michx. is a tolerant plant, meaning that it can grow in a wide temperature range. The ideal temperature range for this plant ranges between 10° to 28° Celsius. During winter, the temperature should not fall below 5° Celsius. The plant needs a coldness period to induce dormancy; hence it is advisable to keep the plant at a lower range of the temperature during winters.
Soil Requirements
For Pinguicula pumila Michx. to grow optimally, a well-draining growing medium is crucial. A combination of peat moss, sand, and perlite yields ideal results. A soil pH between 6 and 7 is ideal for this plant's growth, which means the growth is optimal when soil is slightly acidic to neutral. When watering plants, avoid the use of hard water as the build-up of minerals will harm the soil and plants in the long-run. To maintain optimal health, avoid the complete drying of the soil.

- Alternatively, you can place pots in trays of water (without submerging them) to help keep the soil moist without increasing the humidity levels excessively.
Fertilization for Pinguicula pumila Michx.
The Pinguicula pumila Michx. is not a heavy feeder, but it requires some nutrients to stay healthy. Here are some tips on fertilizing the plant:
- Use a balanced fertilizer or one intended for carnivorous plants, such as 10-10-10 or 12-12-12.
- You can fertilize the plant once a month during the growing season, May to August
- A modified method of fertilizing is from a tea bag of fish meal in a large water volume and keeping it for some hours before adding the solution into the soil in the pot
- Do not overfeed the plant as it can lead to nutrient lock, and the plant will die gradually
Pruning for Pinguicula pumila Michx.
Pinguicula pumila Michx. does not require much pruning but removing the dead leaves and flowers can significantly improve the plant's appearance.
- Trim or pluck the dead or damaged leaves and flowers as they appear to allow the plant to allocate resources to newer growth and blossoms.
- If you notice leaves turning yellow or browning, it could be a sign of over-exposure or sudden change in environmental conditions. If you suspect this is the cause, avoid cutting them and modify the growing conditions accordingly.
- If removing flowers or leaves, be careful not to damage the neighboring shoots which are extremely fragile.
Propagation of Pinguicula pumila Michx.
Pinguicula pumila Michx., commonly known as the southern butterwort, is a carnivorous plant that can be propagated through several methods. Here are some of the propagation methods for this plant:
1. Division
Division is the easiest and most common way to propagate Pinguicula pumila. The rosette can be gently pulled apart to reveal a cluster of individual plants, each with its own root system. This method is best done during the spring or early summer when the plant is actively growing.
2. Leaf Cuttings
Pinguicula pumila can also be propagated by leaf cuttings. Cut a healthy leaf from the plant along with the entire petiole (leaf stalk) and place it on a damp peat moss or a 50:50 mix of peat moss and perlite and cover it with a plastic cover. Keep the cuttings in bright, indirect light and high humidity. Over time, the leaf will develop small plantlets at the base of the petiole and new leaves will form at the tip.
3. Root Cuttings
Root cuttings can be taken from Pinguicula pumila during the plant's dormant period, usually in the fall. Cut off a section of the root that is about 2-3 inches long and plant it in a pot filled with a well-draining soil mix. Keep the soil moist and in a bright location but out of direct sunlight. The cuttings will develop new plantlets within a few months.
4. Seed Propagation
Pinguicula pumila can also be propagated from seeds. Sow the seeds on the surface of a damp soil mix and cover the pot with plastic. Keep the pot in bright, indirect light and high humidity. The seeds will germinate in about 4-6 weeks. After the seedlings have developed a few true leaves, they can be transplanted into individual pots.
Propagation of Pinguicula pumila is relatively easy and provides gardeners with a great way to increase their stock of these unique carnivorous plants.
