Widely used in Southeast Asian cuisine, particularly Vietnamese dishes, soups, curries, and fresh salads, this versatile herb is a must-have for home cooks seeking authentic flavours straight from the garden.

Fast growing and easy to maintain in warm conditions, Laksa Leaf thrives in part shade to full sun with consistently moist, well-drained soil. Its spreading growth habit makes it ideal for garden beds, herb gardens, and container planting, where it can be easily harvested year-round in suitable climates.
