Nepenthes Maxima Cultivation
Nepenthes maxima is an easy plant, with lowland and highland varieties.
Cultivating Ease - Easy
Type - This plant has two distinct forms and many different varieties. The lowland variety grows 60 meters and up. Highland varieties can range to well over 2000 meters, but none of the forms I grow are difficult, and all can be grown as intermediates. The lowland forms can be grown in a stovehouse.
Temperature - Daytime temperatures can range from 80-95 degrees. Nighttimes temps between 60 degrees and 70 degrees for the highland forms, and above 80 for the lowlands.
Humidity - The humidity should remain above 70% for best growth.
Light - Semi-shaded light to full sun.
Moisture - Keep the plant moist. I usually grow this plant on a tray method. I sit the pot on about 1" of water, and over a week or two the water will evaporate and the soil will start to dry a bit. I then water again.
Soil - Long Fiber Sphagnum
Size - The plant will eventually start climbing, and will grope about the rest of your collection. It will need to be pruned every 6 months to a year in order to keep it in check unless you have ample room for it to run around in.
Details: An easy plant that produces beautifully shaped lower and upper pitchers. There are many different forms of the plant, with many of them not formally documented. It has a decent range covering a good amount of area and altitude, so it should not be uncommon to have many different forms. All forms appear easy. All forms have a filiform appendage at the tip of the lid overhanging the mouth. This appendage can be quite long in some forms.
Propagation - Very easy from cuttings. The plant produces many offshoots from the basal area as well. Small tc plants grow into large plants in a very short amount of time.
Forms - lowland & highland. There are also a multitude of different varities and forms. Some are named after the area of origin, such as "Sulawesi", and others are named after color or size, such as "deep purple" or minor. The colors vary from total green in the Sulawesi form, to very very dark scarlett purple in the deep purple form. The typical form has purple cylindrical lower pitchers, and green specked uppers whichhave a candy cane striped peristome and infundibulate. In some forms, such as Sulawesi and Pierenensis, the persitome can be quite rounded.
