Pinguicula sp. ‘Guatemala’ | Guatemala Butterwort
Broad lime-green leaves and a substantial open rosette give Guatemala Butterwort a very different look from many of the smaller Mexican Pings. During active carnivorous growth, the fleshy leaves are covered in tiny glistening glands and can develop a beautiful peach, pink or reddish blush under stronger usable light. The plant circulating in cultivation as Pinguicula sp. ‘Guatemala’ is an unidentified Guatemalan locality plant, commonly associated with a high-elevation collection around 3,100 meters. Because its species-level identity has not been reliably established, keeping the locality name is more accurate than assigning it a species name.
New leaves develop from the center and gradually build a broad, overlapping rosette that can reach approximately 4–5 inches across under good growing conditions. Its root system is extremely small and shallow compared with the foliage above it, often remaining immediately beneath the substrate surface. That is normal. Watch the center of the rosette because the newest leaves give you the clearest picture of what the plant is doing now.
For natural light indoors, place it directly in an east-facing window or approximately 1–2 feet from a south-facing window, aiming for approximately 1,000–2,000 foot-candles at the leaves. Foot-candles simply tell you how much light is actually reaching your plant. Strong usable light supports a compact, substantial rosette and can encourage the warmer pink and reddish tones this Ping is capable of producing. A healthy green plant is still a healthy plant. Use the size and quality of the newest leaves along with color when evaluating its light.
Under a grow light, use a full-spectrum 5000–6500K fixture approximately 6–10 inches above the rosette, aiming for 1,000–2,000 foot-candles at the leaves. Keep the fixture centered over the plant so the entire rosette receives usable light. Because this is a high-elevation locality Ping, good light paired with comfortable indoor temperatures and airflow supports strong growth better than trying to create an excessively hot growing environment.
Water when your plant needs watered. For Pings at Rooted, that starts with distilled water, reverse-osmosis water or rainwater rather than mineral-heavy tap water. During active carnivorous growth, wet the plant and upper root zone from above in the morning and again in the evening. Its roots sit very close to the surface, allowing you to keep moisture available where the plant is actually using it while the open substrate remains aerated. The pot does not need to remain continuously standing in water.
Give those shallow roots a loose, open substrate made from approximately half organic peat moss and half coarse mineral material. The mineral portion can include coarse pumice and natural aquarium sand or fine gravel. The finished mix should remain visibly gritty and open while containing enough peat to hold some moisture around the shallow roots. Keep the crown at the surface rather than burying the center. If you eventually repot a large healthy rosette and discover only a surprisingly small amount of root underneath it, that shallow root system is normal.
During carnivorous growth, the sparkling droplets covering the leaves are called mucilage. The plant produces them to capture fungus gnats and other tiny insects and absorb nutrients from its prey. Insects caught across the leaves can remain there while the plant uses them, and the sticky foliage does not need to be wiped clean. For additional nutrition, Rooted grows Pings using Schultz Cactus Plus 2-7-7 diluted at one full dropper per ½ gallon of distilled, RO or rainwater. Mix it thoroughly into the water and use the diluted solution during active carnivorous growth so the foliage receives nutrition as the plant is wetted.
Guatemala Butterwort can also change its appearance as its seasonal growth changes. Watch the center of the rosette. New leaves may become smaller, thicker and more tightly arranged, with less of the sticky mucilage seen across the broad carnivorous foliage. The transition can be less dramatic in some plants and growing environments than in Pings that form an extremely tight winter rosette, so let the individual plant show you how strongly it changes. As the rosette becomes smaller and growth slows, its water use decreases as well. Reduce moisture along with the plant rather than continuing to wet a much smaller rosette at the same rate it used during active growth.
The return to carnivorous growth begins in the center. New leaves become broader again and develop their sticky glandular surface as the plant becomes more active. Gradually increase moisture with the expanding rosette and return to its regular carnivorous-growth feeding routine. The newest foliage gives you the signal rather than a particular date on the calendar.
Flowers rise above the foliage on slender stalks and can be allowed to bloom normally. Older outside leaves can gradually decline while healthy new growth continues from the center, especially as the plant changes growth forms. Look at what the center is producing before judging the health of the entire plant by one aging outside leaf.
Success looks like a broad, healthy rosette continuing to produce substantial new growth during its carnivorous phase and healthy compact foliage when its seasonal growth changes. The leaves may remain luminous green or develop beautiful warmer blush and reddish tones as conditions change. Follow the center of the rosette, adjust moisture as its growth changes, and let the newest leaves show you where the plant is in its cycle.
