Cultivating Ease - Very Easy

Type - This plant is a lowland, but can tolerate very cool temperatures as well.

Temperature - Keeping it warm at all times is advisable, although it can tolerate temperatures as low as 35 degrees (non-frost) at night for weeks at a time. Even though it can tolerate cold temperatures, it should be kept between 75 and 95 degrees farenheit for optimum growth. It grows well as an intermediate.

Humidity - This plant needs humidity above 70%.

Light - Shaded conditions to full direct (diffused) sunlight.  It grows very well in a large chamber under lights.

Moisture - Keep the plant moist to wet.

Soil - Long Fiber Sphagnum

Size - The plant can grow to a significant length. Even small tissue culture plants can grow very fast. It is an candidate for larger grow chambers (4'x4'x8') under lights, but pruning every 6 months to a year will eventually be required.

Details: Rafflesiana produces Nepenthes characteristic pitchers, having a high toothed peristome and frilly wings. A very nice first plant.

Propagation -  Plants grown from seed mature relatively fast. Small tissue culture plants also grow rapidly. Rooted cuttings are very easy to take.

Forms - Contrary to Dansers 1928 monograph, rafflesiana has an extraordinary amount of variability. To Dansers credit, many of these have only recently been described. Some forms once known are probably gone from cultivation.

"Typical" - The typical form can occasionally produce frilled winged tendrils.

"Squat Red" - Produces small squat pitchers, with the entire plant and pitchers being colored a dark pink to blood red color.

"White" - Produces whitish green pitchers with red flecking.

"Singapore Giant" - This and a few other giant forms can produce pitchers rivaling that of N. rajah.

"Elongata" - This plant produced greenish leaves and pitchers that can be 2 to 3 times as long as the typical variety.

"Elegance" - A type of elongata that is beautifully colored.

"Alata" - Consistently produces frilled winged tendrils.
