Piper sylvaticum is closely related to black pepper (Piper nigrum) and also grows creeping or climbing. Its shoots can reach several metres in length.
Pepper grows well in partial shade to partial sun with some morning, evening or winter sun. It should not be exposed to full summer sun.
Regular mixes for houseplants and other potted plants or for herbs and vegetables are suitable.
The root ball should be allowed to dry out slightly between waterings, but should not be left to dry out or submerged in water for long periods.
Liquid fertiliser can be applied monthly from spring to fall. Slow-release fertilizing, such as sticks, can be given in spring and summer.
Piper sylvaticum does not need any fertiliser in the first year after purchase or repotting.
Pepper species are native to tropical regions, so as houseplants they like warm temperatures and can be kept at room temperature all year round.
Propagation from cuttings is easy, with most shoots forming aerial roots. Stem cuttings with only one leaf are suitable. They can be planted in moist soil immediately after cutting.
The plant shown here is sold as Piper sylvaticum, but this does not appear to be the case. As this name has become established, I will use it in this article. The “real” Piper sylvaticum looks like this.
