  • Luffa on vine

This type of squash while not strictly a vegetable can be eaten when young. They are more commonly grown to use when mature and dried.

The plants need warmth to grow successfully. Keep inside until all risk of frost is gone.

They grow on vines similar to cucumbers.

A large loofa makes a great back scratcher. Luffa can be cut into many shapes for scrubbing pads, padding, and other uses.

Culinary hints - cooking and eating Luffa

The luffa flowers and fruits are soft and edible when young and are sometimes cooked and eaten like squash or okra. Loofah has been an important food source in many Asian cultures. The leaves and vines should not be eaten.

Hi I bought some loofah seeds on eBay and want to know if I can plant them now. From what I read it would be possible and have fruit by April. Could you please confirm Many thanks Betty

Loofah are cold and frost tender, so if you have a suitable micro-climate that will provide warm weather and enough water until April, it's worth trying.
