🥬 Full Heart Batavian Escarole

What it looks like

Why this variety

Full Heart Batavian is the classic escarole: upright, broad, smooth dark-green leaves with less basal rot than older strains, wrapped around a nicely bunched, creamy-yellow blanched center. It is the imported Royal Sluis NR65 strain, and it has been the standard against which other escaroles are measured for decades.

A note to avoid confusion: this is not the same plant as Broad Leaved Batavian, which already has a guide as an endive variety. Broad Leaved Batavian is the old 1860s heirloom; Full Heart Batavian is the tighter, more upright, later selection bred from that family — similar blood, different plant, and a deeper, better-blanched heart. At 85 days it is a slow escarole, so plant it early in the cool season and give it the full run.

How to grow

Sow seeds 1/4 inch deep, started indoors 6–8 weeks before transplanting or direct-sown in the bed. Transplant at 12 inches apart with rows 18 inches apart. Escarole is a cool-season crop that wants a long, steady run — most types take 48–90 days — so in Florida it belongs to the fall-through-spring garden, planted early enough to head up before heat arrives.

Escarole is the broad-leafed half of endive: same species (Cichorium endivia), but the latifolium variety, with smooth, broad leaves instead of frills. That matters in the kitchen — broad leaves cook down like a green rather than shattering like a salad leaf — and in the garden, because escarole heads blanch themselves more readily. The inner heart turns creamy yellow-white on its own as outer leaves shade it, though tying outer leaves loosely a couple of weeks before harvest makes the heart even paler and milder. For the crop’s curly cousin, see the Endive guide.

Water & feeding

Escarole wants steady moisture — about an inch a week at the soil line, with mulch to hold it. Uneven water causes tipburn and bottom rot, the two complaints that trace back to the watering can. Feed with worm castings at planting and one side-dress as heads fill; escarole is a moderate feeder, and in sandy soil a split feed beats one big dose that washes past the roots. Water in the morning so leaves dry before night.

Common problems

• Bolting in heat — a central stalk means the plant has decided summer is here. Plant for the cool months, choose slow-bolting types like Coral, and harvest before sustained warmth.
• Tipburn — brown, papery leaf edges, usually from uneven water and fast growth. Mulch and water evenly.
• Bottom rot — mushy lower leaves in wet, crowded conditions. Give airflow, space properly, and avoid overwatering late in the day.
• Slugs and snails — ragged holes and slime trails, worst after rain. Beer traps, boards flipped in the morning, and mulch pulled back from stems help.
• Aphids — clusters in the heart and on undersides. Blast with water or use insecticidal soap; check hearts before eating.

Harvest

Cut escarole heads whole at the base when full and firm, with a well-blanched creamy heart. Outer leaves can be picked earlier for cooking, but the head is the prize — a tight, pale-centered rosette that braises beautifully with beans, wilts into soup, or grills in wedges. Harvest in the morning and use within a few days; the broad leaves wilt faster than cabbage but hold better than curly endive.

Saving seeds

Full Heart Batavian is an open-pollinated heirloom — a 1934 All-America Selections winner — so saved seed comes true; let a plant bolt and set seed in the cool season, and isolate it from other endives, which cross readily. The full method is in the Saving seeds section of the Escarole guide.
