Long Pepper Piper longum Vegetable Seeds for Planting

Long Pepper (Piper longum) is a striking ornamental vine appreciated for its glossy heart-shaped leaves and elongated catkin-style fruiting structures. Its climbing habit makes it ideal for trellises, decorative fences, and tropical patio containers. As a warm-season perennial, it performs best in humid, frost-free environments, where it forms dense foliage and dramatic dangling fruit displays.
