10 Seeds Luffa acutangula Thai Ridge Gourd Bitter Luffa Sponge Vine

Luffa acutangula, commonly known as Thai Ridge Gourd or Bitter Luffa, is a vigorous tropical vine prized for its angular, deeply ridged young fruits and its versatile garden appeal. This fast-growing annual produces long, slender green gourds with pronounced longitudinal ridges, and if left to mature on the vine, the fibrous interior can be dried into a natural sponge. Its lush foliage and climbing habit make it an attractive addition to trellises, arbors, and garden fences in warm conditions.

Young ridge gourds are harvested while tender and are a staple in Southeast Asian cooking, where they are used in stir-fries, curries, and soups for their mild, slightly sweet flavor and crisp texture. The vine thrives in full sun with consistent moisture and can reach impressive lengths when given vertical support. As the fruits mature past culinary use, they develop strong internal fibers that can be cleaned and dried for household sponges. Species: Luffa acutangula. Variety: Thai Ridge Gourd.
