Lettuces Lettuce & Chicory

Daisies are the dominant provider of edible summer greens, particularly the lettuces and chicories. Not as stuffed full of nutritional goodness as cabbages, but still plenty good for you and they make a lot of pleasant salads.

Chicory - Endive   -   [Asteraceae Cichorium]


Catalogna Chicory   -   [Italian Dandelion, Cutting Chicory, C. intybus]
Chicory

A mildly bitter chicory popular in Italy and widely available in the USA. There are also cultivars with red stems, and sometimes white ones will show red streaks. Chicory is generally used raw to pep up salads with fairly heavy dressings, but can also be cooked and will then be milder. The photo specimen was 16 inches long and weighed 13 ounces.

Chicory Root   -   [C. intybus var. sativum]
Chicory Flowers

Chicory Root has long been an adulterant in coffee and sometimes a substitute. In East Germany Mischkaffee, a mixture of chicory, sugar beet and rye was used during a coffee shortage before the fall of the Berlin Wall.   Photo © i0130.

Belgian Endive   -   [Witloof, French Endive, Cichorium intybus]
Belgian Endives

This very bitter chicory is pulled from the field and the green top cut off. Replanted in darkness the roots grow new leaves which lack green chlorophyll and are also much less bitter. This process explains the rather high price, but the flavor/texture combination just can't be found elsewhere and is essential to some recipes. The photo specimen was 5 inches long and weighed 4-3/4 ounces.

Belgian Endive - Red
Red Belgian Endives Eager to entertain (and pick up a little yuppie cash), California growers are now marketing a red variety of Belgian Endive. I found the taste indistinguishable from the regular white but the heads were smaller, looser and more expensive. Use it if the color is important to you. The photo specimens were 5 inches long and weighed 2-1/4 ounces each.

Curly Endive & Frisée   -   [Cichorium endivia]
Curly Endive

A plant from India (Cichorium endivia) valued as a salad green. The Curly variety has fairly narrow leaves with ruffled edges while on the Frisée variety the leaf is both curly and very deeply cut making it quite frizzy. Of course there are many cultivars ranging from one extreme to the other.

Escarole   -   [Cichorium endivia]
Escarole

Escarole is less bitter than most chicories and has broad light green leaves and a very flat head. It is commonly used as a salad green but more mature heads may be cooked as a green side dish. The photo specimen was 13 inches across and weighed 13 ounces.

Radicchio   -   [Cichorium intybus]
Radicchio

A moderately bitter chicory that looks like a head of lettuce in the field. In Italy they have also an all white version but in the US the spherical red and white Radicchio di Chioggia variety is most common but an elongated red and white Treviso variety that looks like a big red Belgian endive is also seen. This is a fairly expensive lettuce because of the production method. In the field they are green. To make them purely red and white they are pulled from the ground and put in water in a dark room until the chlorophyll has faded from lack of light. This is labor and capital intensive and a lot of outer leaves are lost in the process resulting in the high price. The larger of the photo specimens was 4 inches diameter and weighed 9-1/2 ounces. Details & Cooking.

Radicchio Treviso   -   [Cichorium intybus]
Treviso Radicchio

This is simply an elongated variety of the regular round Radicchio di Chioggia. It tastes the same and can be used the same unless leaf shape is important to your application, but it's likely to be even more expensive. The photo specimens was 7 inches long, 2-3/4 inches diameter and weighed 7 ounces. Details & Cooking.


Dandelion   -   [Dent-de-lion (Old French), Pissenlit (French), Taraxacum officinale]
Leaves

Originating in Eurasia and now infesting lawns worldwide, this common weed is a highly successful member of the vast daisy family (Asteraceae). Its long taproot makes it very difficult to eradicate and its efficient windblown seed dispersal system assures reinfection. It prefers temperate climate and moist soil, which is why it has such an affinity for lawns. The photo specimen leaves were up to 14 inches long, but they are sold up to about 16 inches.

The plant has both medicinal and culinary value. Young leaves are used raw in salads while older ones are more often cooked or added to soups. . Under their bitterness the leaves have considerable sweetness and have a particular affinity for eggs. Roots are used, as are chicory roots, to make a coffee substitute, and flower heads are used to make dandelion wine. The leaves are a strong diuretic, thus the French name Pissenlit (wet the bed). Herbalists consider dandelion a general tonic and "blood cleanser".   Details and Cooking.

Salsify   -   [Oyster Plant, Vegetable Oyster, Purple Salsify, Goatsbeard: Tragopogon porrifolius]
Whole Plants

Native to the Mediterranean region of Europe, this plant has been introduced to other regions, and now grows wild in almost every state of North America (except the deep Southeast). Salsify has been known to herbalists since ancient times and has been grown not only for its flowers, but for edible roots and stems. The roots are noted for tasting like oysters, thus the alternate names.

This vegetable was popular in England in the 18th century but today is eaten mostly in France, Italy and Russia. It has, however, in recent times often been displaced by Spanish Salsify (Black Salsify, Scorzonera hispanica), a different genus with much broader leaves and yellow flowers rather than purple. The photo specimens were 20 inches long, the root parts being about 7 inches and almost 3/4 inch diameter at the top.   Details and Cooking.

Salsify - Black   -   [Spanish salsify, Black oyster plant, Serpent root, Viper's herb, Viper's grass, Scorzonera; Scorzonera hispanica]
Growing Plants

Native to the Near East and souteastern Europe, this salsify has much wider leaves and longer roots than traditional salsify, and the roots are very dark brown with a corky bark. The roots are not easy to peel and exude a very sticky latex, and peeled root needs to be immediately submerged in water soured with citric acid or lemon juice to prevent browning. Supposedly you can was the latex off your hands with vinegar.   Photo by Rasbak distributed under license Creative Commons Attribution-ShareAlike v3.0 Unported.

Lettuce   -   [Lactuca sativa]

The first depiction of lettuce is from Egypt just under 4000 years ago, but it had been in use there in much earlier times. Egyptian lettuce was similar to our wild lettuce, and similarly reputed to have opiate (and aphrodisiac) properties. Mature lettuce "bolts", sending up a central stalk with many branches holding small dandelion-like flowers. It becomes more bitter and opiate-like when it bolts. Lettuce is a significant source of Lithium.


Butter Lettuce   -   [Butterhead, Boston, Bib or Limestone]
Butter Lettuce

These are very tender loose leaf lettuces often packed in individual plastic containers to protect them from damage. Of the two main varieties, Bib Lettuce is the smaller and considered the more flavorful, but Boston Lettuce is a suitable substitute. Packages I've seen in Southern California do not use either designation but simply call the contents "Butter Lettuce". The package often includes roots and a hydroponic growing matrix to extend shelf life.

Green Leaf Lettuce
Butter Lettuce

Green Leaf is too tender to be a good industrial product but it's a very fine base for quality salads. Plenty of lettuce flavor with very moderate bitterness and good color. The photo specimen, squished a bit flat in shipping, as they always are, was 14 inches wide, 10 inches from stem to tip and weighed 13 ounces.

Iceberg Lettuce   -   [Crisphead lettuce]
Iceberg Lettuce

Crisphead is actually the correct name, but nobody calls it that name. This head lettuce is the darling of the lettuce industry and the fast food chains. It's easy to handle and stands up well to processing and shipping abuse. The fast food people like it because it's easy to shred, bulks up a salad well and stays crisp and bulky for quite a while after shredding.

This lettuce was originally (and still is) grown in Salinas, California. It was put on trains, packed with ice and shipped as far as Maine year round, thus called "iceberg lettuce". It was very much welcomed during New England winters.

Crisphead lettuce contains a lot of water and is 1/5th or less nutritious as loose leaf lettuce. It has rather little lettuce flavor or bitterness but can be useful for recipes that call for lettuce wedges and such or where texture is more important than flavor or nutrition. It's also easy to store in the fridge compared to leaf lettuce. The photo specimen, a somewhat smallish one, was 5 inches diameter and weighed 1-1/3 pound.

Mâche Lettuce
Mache

Not actually lettuce, but a member of the Valerian family.

Red Leaf Lettuce
Red Leaf Lettuce

Very similar to Green Leaf Lettuce except for the color. For taste and texture the two are interchangeable. The color is caused by anthocyanin pigments which are the same antioxidants found in red cabbage and red wine.

Romaine Lettuce   -   [Cos Lettuce]
Romaine Lettuce

The second most common lettuce in America after Iceberg and the sturdiest of the leaf lettuces. It's shape and stiffness make it relatively easy to handle but it does have quite a bit more lettuce flavor than iceberg does. It is called for by many recipes where the leaf shape and stiffness is desirable. The photo specimen was 13 inches high. It is often used as a foundation layer on a platter with the featured items placed over it.

Ruby Lettuce
Head of Lettuce

Pretty much the same as Red Leaf Lettuce except for being all deep red with almost no green. For taste and texture the two are interchangeable. The color is caused by anthocyanin pigments which are the same antioxidants found in red cabbage and red wine.

A Choy   -   [Taiwan Lettuce, Chinese Lettuce; Yu Mai Tsai (China)]
Leaves

This is the only common leaf lettuce in China and is popular in stir fries in Taiwan. It is always cooked - raw salads are not eaten in China due to unsanitary growing conditions. This lettuce is now widely available in markets serving a Chinese community - well it is here in Southern California anyway. It is much like a romaine lettuce, but more bitter

Stem Lettuce   -   [Celtuce, Celery Lettuce, Asparagus Lettuce, Chinese Lettuce; Wosun, Woju (China); L. sativa var asparagina alt var augustana, var angustata]
Stems w/Leaves

This lettuce is grown mainly for its stem, which is peeled and sliced or diced and used in stir fries. The flavor is fairly mild, much like a slightly bitter cucumber, so it's usually paired with stronger flavored items. The photo specimens were about 17 inches long (not counting leaves), 1.6 inches diameter and weighed about 8 ounces each. The form shown with a crown of leaves is how it is generally sold. The leaves are like Romaine leaves but tougher and more bitter, but stand up better to cooking. The Chinese do not eat raw greens for reasons you'd probably rather not dwell on.   Details and Cooking.

Wild Lettuce   -   [prickly lettuce, Lactuca serriola]
Wild Lettuce

This is where it all came from, a wild plant with a bitter milky sap. When the plant matures it will "bolt", sending up a central stalk topped with a group of small dandelion-like flowers. The bitter sap is a mild opiate, particularly when the lettuce bolts. The photo shows leaves of very young plants, the leaf margins become deeply cut, ragged and pointy looking.

While wild lettuce is much stronger, other loose-leaf lettuces have similar properties. Some years back I observed that the loose-leaf lettuce in a friend's garden had bolted. Connie remarked that it wasn't as good as before but they were still using it. They were also wondering why they were falling asleep right after their salad (served at the end of dinner in their household).

My pigeons used to rip into the wild lettuce, then go and flake out on the roof, often lying upside-down. Unfortunately they can't do that anymore - there are too many hawks now.


Health & Nutrition

Lettuces vary a little in nutritional content, but they are all very high in vitamin A and beta carotene (which converts to vitamin A). The redder the variety, the more they have. They also contain good quantities of Vitamin K, Vitamin C, foliates, zia-xanthin and B complex, as well as a good selection of minerals and antioxidants. Lettuces are all very low in calories (15 per 100 grams) and are fat free. They do contain oxalic acid, but only 0.33mg per 100 grams.

Lettuces are known to help prevent osteoporosis and iron-deficiency anemia, and are suspected to be beneficial for cardiovascular disease, ARMD, Alzheimer's disease and cancers. Of course, all this is subject to our CloveGarden Medical Disclaimer.
