Evergreen (Escarole)
Endive & Escarole in the US

Getting Endive and Escarole started from seed is how you'll do it, as you don't often see plug plants for these. Sowing times vary a fair bit by your USDA zone, so check the GrowMore CookMore app for the best dates for you, from late winter in warmer zones right through to fall. Pop seeds about 1/4 inch (0.5 cm) deep, spaced an inch (2.5 cm) apart. You can sow indoors or direct outside, depending on the variety and your weather. Aim to keep the soil consistently moist but not waterlogged. A little succession sowing every few weeks will give you a steady harvest rather than a massive glut all at once, you know what I mean.

If you've started your seeds indoors or undercover, you'll want to prick out the strongest seedlings when they're big enough to handle, moving them into individual pots. Once they've got a few true leaves and all danger of your last frost has passed, start hardening them off gradually over a week or so. Then, you can plant them out into your garden, giving them about 10-12 inches (25-30 cm) of space between each plant. They're fairly sturdy once they get going and don't usually need any support.
