Botanical Overview

Plant Description

Betel leaf distinguishes itself from Betel pepper (Piper betle) and is an evergreen creeper reaching up to 90 cm. Featuring shiny heart-shaped leaves and small white flower spikes, it thrives in rich, well-drained soil with partial shade. While it prefers consistent moisture, it is sensitive to waterlogging. Although frost can damage leaves, a well-established plant survives. In colder areas, it can be cultivated in hanging baskets or large pots, moved to a sheltered spot during winter.


  1. Culinary Applications: The spicy leaves are culinary treasures, utilized both raw and cooked in Southeast Asian cuisine. For raw consumption, young tender leaves work best. In Thailand, ‘mieng kum,’ a popular snack, involves using betel leaves as wraps for fillings like peanuts, shrimp, shallots, lime, and raw ginger. Soaking leaves in cold water with a hint of sugar subtly alters their flavor.
  2. Medicinal Uses: Beyond its culinary contributions, betel leaf boasts various traditional medicinal applications.

Planting Details

  • Planting Time: Propagation from cuttings is straightforward, especially during warmer periods.
  • Planting Depth: Cuttings, approximately 25 cm long, should be stripped of leaves on the bottom half, buried to half their length in potting mix, and kept consistently moist.
  • Spacing: Optimal spacing is between 60 to 100 cm apart, allowing the plants room to spread.
