What’s the Difference Between Spinach and Romaine Lettuce?
Romaine Lettuce and spinach are very different plants with vastly different origins.
Romaine Lettuce (Lactuca sativa L. var. longifolia) is called ‘cos’ lettuce in the United Kingdom. Across the European continent, it is known by various names, all of which roughly translates to Roman Lettuce in the local language. The North American pronunciation of Romaine is believed to have been brought over by early French settlers who referred to the leafy green as ‘aslaitue romaine.’
Spinach, also known as ‘Persian Green,’ originated in Nepal and was cultivated in China as early as 647 AD. The modern pronunciation comes to us by way of France. In the 14th century, the Middle English word ‘espinache’ was adopted from the French ‘épinard.’
Appearance and Cultivation
Romaine can be tall, bolting to 3 feet or more in hot or dry conditions. Optimally it should be harvested at around 12 inches. It has frilly green leaves with a stiff central rib that grows around a central head or heart.
Spinach has triangular or oval leaves that are a darker green than Romaine. These leaves grow in an alternating pattern on stalks that originate from a root core.
Both spinach and Romaine Lettuce are cool weather crops preferring temperatures in the mid 50’s to low 70’s. However, Romaine is much more heat tolerant than other lettuce varieties or spinach.
While spinach will wilt and die if the weather gets too hot or it receives too much direct sunlight, Romaine will bolt and go to seed.
Both plants prefer loose, loamy soil with a nearly neutral pH. Spinach can withstand poor soil conditions better than Romaine but is more water sensitive.
No lettuce variety can match spinach for nutritional content, but Romaine fares better than most.
- Is higher in pantothenic acid.
- Is lower in sucrose and higher in glucose.
- Is lower in saturated fatty acids and higher in monounsaturated fatty acids.
- Contains more gamma-tocopherol and delta-tocopherol.
- Is higher in fiber.
- Supplies more protein.
- Contains more vitamins A, C, and E.
- Is higher in calcium, iron, potassium, magnesium, and manganese.
- Supplies higher or equal levels of all nine essential amino acids.
Taste Differences Between Romaine Lettuce and Spinach
Romaine lettuce has a juicy, refreshing flavor that is less sweet than iceberg but not as grassy as spinach and with just a bit of a bitter edge in the larger leaves. The heart of a Ceasar salad, Romain, has a mild flavor at home with a light gingery vinaigrette yet still robust enough not to be overpowered by the thickest Ranch Dressing.
Spinach has a stouter earthy taste with a milder sweetness than Romain and a distinct grassy note that can be slightly bitter when larger leaves are eaten raw. Wilting with olive oil brings out spinach’s sweeter side, as does steaming.
