Ce qu'on demande souvent

Do I need two plants for fruit?
Yes, you generally need at least two plants for cross pollination to ensure a good harvest.
When is the fruit ripe?
The fruit is ripe when it fills the husk and the husk begins to dry and split open.

D'où vient le nom

The genus name Physalis comes from the Greek word for bladder, referring to the inflated husk, while philadelphica refers to its historical classification.

Bon à savoir

  • Tomatillos are a staple ingredient in Mexican green salsas.
  • They are also known as husk tomatoes.
  • The sticky film on the fruit is a natural defense against insects.
