About Broadleaf Batavian Endive: Endive, a member of the chicory family, most likely originated in Egypt or the Mediterranean region. Pliny the Elder praised its medicinal properties, stating that it purified the blood and cured insomnia. By 1200 AD, many varieties of endive were known throughout Europe; the first American reference to this vegetable comes from an 1806 cookbook. Endive still thrives in the gardens and kitchens of Mediterranean countries, where it often makes a tasty addition to salads.
Broadleaf Batavian Endive Germination: Endive makes an excellent fall crop, since light frost sweetens the taste, and excess heat causes bitterness in the leaves or bolting. For an early summer crop, sow seeds indoors 2 months before the last spring frost; sow them 1/4" deep. When the seedlings emerge, thin them to 6" apart. Four weeks after planting them, set them outside 12" apart. For a fall crop, direct sow seeds in July. Water the ground, scatter the seeds on the surface, then cover with 1/3" of soil. When the seedlings emerge, thin them to 12" in all directions. Areas with warmer winters may be able to plant a winter crop about two months before the last frost.
Growing Broadleaf Batavian Endive Seeds: Keep the soil moist to prevent toughness or a bitter taste, but avoid getting the leaves wet as this may cause rotting. Mulch helps conserve moisture and control weeds. If desired, blanch the leaves about 2-3 weeks before harvesting by tying together the outer leaves to shade the inner part of the plant. Make sure that the leaves of the plant are completely dry before tying them, or rotting may result.
Harvesting Broadleaf Batavian Endive: Cut individual leaves for baby greens as soon as they reach a good size for eating. Cut mature heads off at the base. For additional growth, leave an inch of stem.
Saving Broadleaf Batavian Endive Seeds: Endive needs to be overwintered in order to produce seed. For areas with severe winters, this requires cutting the plant down to 2" and storing the roots in a humid location in damp sand at 33-40 degrees F until spring, when they can be replanted. Endive can survive milder winters with a thick layer of mulch. Allow the plant to flower and go to seed; when the seed heads are dry and the seeds feel dry and firm, spread them out on a surface to dry for at least 10 days. Either plant the seed heads whole or clean them by putting them in a bag and applying pressure with a heavy weight. Store the seeds in a cool, dry place for up to eight years.
