Black pepper (Piper nigrum) | seeds, 10 pcs.

Latin name: Piper nigrum
Danish names: Peberplante, sort peber
English names: Black pepper plant, pepper vine

Piper nigrum is the plant behind our well-known spice black pepper – and, in reality, green and white pepper as well. It is a flowering, tropical climbing plant that originally hails from India, where it grows in warm and humid rainforests. To succeed in cultivation, it is therefore important to be able to offer roughly the same conditions with warmth, humidity, and support to climb on.

The plant develops long, winding shoots with shiny, dark green leaves and forms hanging spikes of small flowers, which later turn into the familiar peppercorns. It is actually the same plant that gives rise to the different types of pepper:

• Black pepper: boiled and dried unripe fruit
• Green pepper: dried unripe fruit
• White pepper: ripe fruits with the pulp removed

This makes Piper nigrum one of the world's most important and versatile spice plants.

Cultivation and requirements

Piper nigrum thrives best in bright, but not direct harsh sunlight, similar to conditions in a tropical understory. It prefers humus-rich, well-drained, and moisture-retentive soil, consistent watering without sitting in water, high humidity, as well as warmth and stable temperatures.

The plant is not frost-tolerant and is grown in Denmark as an indoor plant, in a greenhouse, or a conservatory. The temperature should preferably be kept above 18 °C for optimal growth.

It needs support, such as a moss pole or trellis, as it naturally grows as a climbing plant.

Tip: Pepper does not like being repotted or moved. It is therefore a good idea to find a stable growing location from the start and limit repotting as much as possible.

Growing from seed

Seeds of Piper nigrum require warm and stable conditions to germinate. For the best result, it is recommended to soak the seeds in lukewarm water for 12–24 hours before sowing. Sow them in a light, humus-rich, and well-drained soil mix, keep the temperature at 25–30 °C, ensure high humidity, and keep the soil evenly moist, but not wet.

Germination can be slow and take several weeks to months. Young plants grow slowly at first and need stable conditions without fluctuations in temperature and humidity.

Utility and collector value

Piper nigrum is one of the world's most used spice plants and has been traded for millennia. The opportunity to grow your own pepper plant completely from seed makes it a particularly exciting utility and collector plant.

In practice, it requires warmth and time to reach your own production of peppercorns, but the plant itself is decorative with its shiny leaves and climbing growth.

For plant enthusiasts, it is a unique opportunity to grow one of the world's most important spice plants – and at the same time gain insight into how the different types of pepper actually arise.

Piper nigrum is an obvious choice for the patient plant lover who wants to grow real pepper completely from seed – a tropical climbing plant with historical, culinary, and botanical significance.
