Endive is a leafy chicory relative that forms a frilly, slightly bitter head used in salads. The curly-leaved type is often called frisée, and blanching the center reduces the bitterness.
About Endive (Frisée)
Endive (Cichorium endivia) is a leafy chicory relative from the Mediterranean that forms a frilly, slightly bitter head. The curly-leaved type is often sold as frisée. It grows as a rosette and fits a 5-litre pot, which makes it manageable on a windowsill with medium light, a practical salad crop for a small space if you don't mind a little bitterness.
The trick growers use is blanching: tie up or cover the center for a week or two before harvest, and the inner leaves pale and sweeten. Keep it cool and evenly watered, because heat and stress push the bitterness up. You can also pick outer leaves young if you prefer milder greens. It takes medium light and moderate water. A head is ready around 65 to 90 days from sowing.
What it’s like to grow
Endive rates moderate because getting it sweet takes the extra step of blanching and steady cool conditions. Left in heat or unblanched, it turns aggressively bitter, which is the most common disappointment. A wet, dense center invites slugs and rot, so don't overwater into the crown. It grows in medium light with moderate water. Worth a little fuss if you want a crisp, slightly bitter salad, and it is non-toxic to cats and dogs.
What to expect
First harvest in about 65–90 days. It asks for a little consistency, but nothing fancy. No sunny window? It also does fine under a clip-on grow light.
