This is the classic romaine. Its compact, dark green rosette of tall, upright leaves is slightly curly with white hearts and has a crisp, sweet flavor. Slow to bolt. Grows best in full sun, but will tolerate partial shade and even appreciates it in spring in hot climates.

  • Light Full sun to part shade
  • Head size 8 inches (semi-heading)

Nutrition Information

Light requirements: Full sun to part shade. Protect plants from strong spring or afternoon sun in warmest regions.

Planting: Space 6 to 18 inches apart, depending on lettuce type. (Read the stick tag that comes with the plant for specific spacing recommendations.)

Soil requirements: Lettuce needs moist but well-drained, nutrient-rich soil. Amend soil with compost, blood meal or other organic matter prior to planting. Fertile soil helps fuel fast, tender leaf development. Soil pH should be 6 to 7.

Water requirements: Keep soil consistently moist throughout the growing season — that is the key to tender leaves. Mulch soil to reduce water evaporation and keep lettuce clean from splashing soil.

Frost-fighting plan: Lettuce thrives in cold weather—established plants tolerate light frost (28 to 33ºF), and some types even withstand lower temperatures. Frost sweetens leaf flavor. It’s a good idea to protect newly planted seedlings from late spring or early fall frosts by covering plants with a frost blanket.

Common issues: Pests to watch out for include aphids, slugs, and small green caterpillars.

Various fungi can attack leaves during rainy weather. Once flowers begin to form, leaf flavor becomes bitter; harvest remaining leaves immediately.

Harvesting: Harvest leaves as soon as they’re large enough to eat. Pick baby leaves for salads, or wait for maturity. To extend the harvest, pick outer leaves first and allow center leaves to enlarge. For leaf lettuces, consider using a cut-and-come-again method. Cut the entire plant at the base, leaving a short stub to resprout. If harvesting frosted or frozen lettuce, allow leaves to thaw out before picking.

Storage: Refrigerate unwashed leaves wrapped in dry paper towels in a loosely closed plastic bag. Leaves store from 5 to 10 days, depending on type.

Nutritional Information

Like all lettuces, romaine is extremely low in calories and high in water content (about 95 grams in 1 cup). However, romaine packs a larger amount of vitamins, minerals, fiber, and phytonutrients than other popular types of lettuce. The fiber, vitamin C, and beta-carotene content makes romaine an especially good vegetable for heart health. High amounts of folate and potassium add to the heart benefits. Romaine is also an excellent source of lutein, a yellow-colored phytonutrient found to be important to eye health.
