all lettuces, romaine is extremely low in calories and high in water content (about 95 grams in 1 cup). However, 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. This eye-catching romaine deserves a spot in both the vegetable and the flower garden. Colorful leaves start out green, then fade to a deep red-bronze as they mature. Red Romaine leaves bring a sweet, flavorful crunch to salads and sandwiches. The heads (if allowed to form) are thick enough to grill. Plants are slow to bolt and grow best in full sun, but will tolerate partial shade and even appreciate it in spring in hot climates. Resistant to mosaic virus. ? Light: Sun to part shade ?
