Nepenthes campanulata N. campanulata on Gunung Mulu  CC BY-NC 4.0 by Tom Holenstein Family Nepenthaceae Genus Nepenthes Clade Insignes Species Nepenthes campanulata Author Sh. Kurata Distribution Borneo Climate Lowland - Intermediate Space requierement small Growth habit Rosette Tolerance medium Pitcher size < 10 cm Nepenthes campanulata is a rather small species native to East Kalimantan in Borneo. It has several rather unusual characteristics that are not found in many other species. These include its very compact growth habit and the fact that it does not climb. Plants with a height of around 10-30 cm are already fully grown and capable of flowering. In addition, the pitchers have only a very narrow peristome, which is why it is sometimes referred to as the lowland Nepenthes inermis. The pitchers reach only about 5 to 10 cm in size and do not have a particularly long lifespan. However, the pitcher opening is very wide and can reach up to 5 cm in diameter. The leaves grow to around 12 cm long and 2 cm wide. Occurrences of Nepenthes campanulata are found on moss-covered limestone cliffs that are otherwise mostly devoid of substrate, at elevations of 300 to 400 m above sea level. Some of these sites are located directly on steep slopes. The habitats have high humidity and are very bright. This species prefers daytime temperatures of 24 °C to 30 °C and nighttime temperatures not below 18 °C. Nepenthes campanulata is a fairly widely available species, although it can still be problematic for some growers when kept as a pure species. There is also a wide range of hybrids involving Nepenthes campanulata, many of which have inherited the characteristic bell-shaped pitcher opening. Most plants available in cultivation have purely green pitchers, although a few forms with red speckling inside the pitchers are also known. Cultivation Ideal Conditions Parameter Suggestion Notes Temperature (Day) 24–28°C Works well in Lowland to Intermediate tropical climate Temperature (Night) 18–22 °C Shouldnt fall below 15 °C Light 100–300 PPFD Growths lithophytic on limestone cliffs, with constant small amounts of water running down the wall, gets a fair amount of light. Still all in cultivation from Gunung Mulu site arent that exposed to light Humidity 40–90 % It seems that also lower humidity isnt an issue for this species, still a bit higher amounts seems to be fine at around constant 60-70% Substrate & Fertilizing Parameter Suggestion Notes Substrate AKP, Sphagnum mixed with Limestone AKP is working well, Nerz said he uses Sphagnum 3/4 with limestone 1/4. Akadama/pumice 50/50 can work very well too. Potsize medium The plant has really sensitive roots which break off with ease. Preventing often repots by choosing a pot which fits it for a long time is better Watering Always keep very moist Seems to doesnt like to sit in water or having drops on the leaves for too long Fertilizing around  500-1000 µS every week Needs a bit more fertilization than other Nepenthes species Fertilizer Tolerance high Feels good with a good amount of fertilization Unique characteristics  Non vining species Fresh and still folded leaves and tendril tips can appear black cause of the hairs Roots are very fragile Flowers even with just 10cm diameter and very regularly Doesnt produce upper pitchers, but the maturity changes the appearance of the pitchers a bit Difficult to hybridize as the seed parents: probable endospermic incompatibility Galery General Pictures User Cultivatad Plants  Picture Conditions Temperature Summer Day: 24–30 °C Summer Night: 23–28 °C Winter Day: 25–28 °C Winter Night: 21–23 °C Humidity 85–95 % Light Intensity around 150 PPFD Notes Campanulata AW Clone 08 AKP Substrate always a bit moist Fertilized every 14 Days - 1200µS Hakaphos Biggest Pitcher: 5cm Cultivated By: Kevin Weblinks Wikipedia – Nepenthes campanulata Nepenthes campanulata on iNaturalist Nepenthes campanulata in the Carnivorous Plants Database More Nepenthes-Species on Carnipedia
