Luffa aegyptiaca

Luffa aegyptiaca

Luffa aegyptiaca or Sponge Cucumber is an annual climbing or creeping plant from the family of Cucurbitaceae or cucumber-like plants.

The fruit is edible when young but is best known as the inside of the ripe fruit that can be used as a sponge (loofah). This sponge is best known in Europe as a sponge for personal hygiene but can also be used for washing dishes and especially to scrub pans.

Fun to grow yourself because, like most of the Cucurbitaceae, the plant becomes very large (up to 9 m) and quickly covers any support with long stems and fairly large leaves.


Luffa aegyptiaca is an annual vine that quickly covers any support it finds. When it finds no support it crawls along the ground.

The leaves are large and lobed with silvery spots on the top.

The yellow, striking flowers measuring 5-7.5 cm in diameter and have five petals.

The fruit is green, up to 60 cm long and 7.5 cm in diameter. It is cylindrical and smooth and slightly wider at the tip. Young fruits is small and looks like okra or cucumber. On older fruits, the outer shell eventually turns brown and papery.
