Nepenthes Argentii Cultivation
Nepenthes argentii is a rather rare plant in cultivation. It is also known as the bat plant due to winged appendages under the pitcher lid.
Cultivating Ease - Medium Some folks report it is difficult to get the plant to pitcher, but it is relatively easy if given the correct growing conditions.
Type - This plant is an intermediate highlander, being found at 1400M.
Temperature - Treat this plant as an intermediate or highland.
Humidity - Keep the humidity above 75% at all times, and it should grow well.
Light - Bright light to full (diffused) sunlight. This plant appears to need very high light levels.
Moisture - Keep the plant moist.
Soil - Long Fiber Sphagnum (This is almost a mandatory mix due to its growth habit)
Size - This may be the smallest of all Nepenthes plants. However, it should be grown in a wide pot for pitcher development.
Details: N. argentii seems to refuse to pitcher in cultivation if the plant is not allowed to throw its tendrils into the soil first. The tendrils can be very long, even thought the plant itself is rather small. The plant will thrust a tendril into the soil immediately below the leaf, and the tendril will emerge further away from the plant. The pitcher will then form slightly underground, so that the pitcher is either partially buried or just sitting on top of the soil when it opens. The pitchers have a couple of feathered type appendages under the lid, with an appearance of bat wings. The plant grows in a very harsh climate, and is exposed to extreme wind and rain conditions, followed by intense sunlight. The plant forms very long tendrils, and will plunge pitchers into the soil as to anchor it from the strong winds. The plant stem will eventually elongate, but it appears to do this to continually climb out of leaf litter and debris that builds up around it. Being a small plant, it can easily be covered with this litter material, and so its very reason for climbing appears to keep above all of this. In the wild, it isn't unusual for most of the stem and pitchers of the plant to be covered, with a small section growing above this.
You must grow this plant in a wide pot if you want the plant to consitently pitcher. Even though currently available plants are only 2"-3" in diameter, I would recommend a 6" to 8" pot.
Propagation - I have yet to propogate this plant.
Forms - I only know of the typical form, which produces reddish/purple pitchers.
