Luffa (Luffa aegyptiaca)

Luffa (Luffa cylindrica): the famous loofah!
Interesting Cucurbitaceae (sometimes called pumpkin) from Asia, used both for the vegetable sponge it produces and for consumption as a fruit (when still unripe).
The plant has a climbing habit but can also be left in the ground.
Easy to grow because it's particularly hardy and resistant to fungal diseases. It requires good irrigation, especially in the early stages. It's vigorous and very productive; rich soil will ensure exceptional results.
Sowing should be carried out in a seedbed at a minimum temperature of 15°C,
It's best to grow it in a heated nursery: the fruit takes several months to ripen, and by growing it early, we'll avoid problems with low temperatures. We recommend growing it under a pergola or climbing support so that autumn rains don't rot the fruit before harvest. The flowers are large and numerous, similar to those of lagenaria but a deep yellow in color, and very decorative.
The fruits can be eaten like courgettes when unripe, the flavour is reminiscent of the latter, with a more herbaceous component.
However, they are not grown for consumption but for the sought-after sponges, as you can learn more about in the next section.
