Propagation
Sow fresh seed during spring and maintain a temperature of 19º to 27º C. (66º to 81º F).

Cuttings taken during spring with 2 to 3 leaves.
Air layering during summer.
Division of the rhizome during spring.

Botanic information
Leaf: The white-pink oblong terrestrial leaves are up to 50 mm (2 in) long and form small rosettes from which a climbing stem appears. Each rosette is surrounded by numerous terrestrial short tub-like green red-flecked pitchers up to 50 mm (2 in) tall with a rounded base. They have 2-fringed wings and an oval mouth with a narrow lip and the 2-keeled lid is narrow.  

The lower larger, dark green leaves produce similar larger pitches up to 88 mm (3½ in) long at the apex from an extended mid rib that acts as tendril and extend down, touching the ground. These pitches are yellow or green to purplish and aerial pitchers higher on climbing stems are rarely seen.  

Flower: The tiny male and female flowers are found on different plants (dioecious) and have small sepals that fold back revealing a protruding style. They are arranged in a spike-like raceme and appear during summer or sporadically in tropical zones. Under cultivation the flowers are rarely produced.

Fruit: The leathery textured capsule contains seeds with a hair-like growth and is dispersed by wind. The small seed is not commonly used and the plant is normally reproduced vegetatively.

Culture
When growing Nepenthes ampullaria in containers apply high nitrogen fertiliser weekly during the growing period and under glass grow in slatted baskets with a loam-less potting mix of sphagnum moss and peat. Place in a bright indirect light, humid position and reduce water during winter. In spring prune shoots back by one third to encourage new pitcher growth.
