Escaped througout most of North America

Florida is the Winter Watercress Capital of the U.S.

Leaf shape can vary

Nasturtium officinale (nas-STUR-shum oh-fis-in-AY-lee ) is one of the oldest leaf vegetables known to be cultivated by man. It’s naturalized in Florida and in fact all of North America, Europe and Asia, the latter two where it is native. Wild watercress is a short-lived edible in central Florida. January to March and maybe a little of April just about sum up its season, and that’s being generous.  Of course the farther north you go the later in the season it can be found such as in Gainesville in May. Locally Watercress  can also be found in drainage ditches leading to the St. Johns River and occasionally along the banks of the St. Johns River.  No doubt in other agricultural areas such as Lake Apopka it can also be found as well as in canals. The only place I have found it past its season is downstream from natural springs that maintain a 72F temperature year round, such as Wekiva Springs.

And while it can indeed by found throughout North America central Florida is the capital of winter watercress production in the United States. The old winter watercress capital was Huntsville, Alabama, but that city traded the mustard member for aerospace technology. I discovered watercress about 23 years ago in Sanford, Fl., some 15 miles north of here.

Given a chance it will root at the nodes

In 1863 Francis Peyre Porcher in his book the “Resources of the Southern Fields and Forests, Medical, Economical and Agricultural, Medical Botany of the Confederate States” wrote of watercress: “Introduced. Ditches Florida. Northward. This plant came into pretty high favor about a century ago [1776] as a spring salad; and it soon obtained preference to all other spring salads on account of its agreeable, warm, bitter taste, and for sake of its purifying, antiscorbutic and diuretic properties. It was greedily gathered in all of its natural habitats within some miles of London for the supply of the London Market, and eventually became an object of regular, peculiar, and somewhat extensive cultivations.” To read more about Dr. Procher read my article on Smilax.

Man is not the only consumer of Watercress. It is eaten by ducks, muskrats, and deer who know a good thing when they find it. Watercress contains significant amounts of iron, calcium and folic acid, as well as vitamins A and C. It has a long history of medicinal use and was even popular in Roman times.  The Greeks thought it was good for the brain and thinking. Many benefits have been attributed to eating watercress, such as that it is a mild stimulant, a source of phytochemicals, a diuretic, an expectorant, a digestive aid and anti-cancerous. Research in Iran has shown it to have antioxidant potential as well as able to lower cholesterol and triglycerides. Research in the United States suggest it has a role in preventing or treating cancer.

Typical four-petaled mustard flower

Cultivated since ancient Persian times, watercress may cause cystitis in some people. It’s consumption is not advised for those who have a delicate stomach or suffer from acidosis or heartburn. I have a tempermental tummy but cooked it has not bothered me. I like it with salt, pepper, olive oil, a sprinkle of garlic and balsamic vinegar.  (I only eat it raw when I collected immediately downstream from a spring.)  Excessive or prolonged use may lead to kidney problems and advise against eating it during pregnancy.

Nutritionally, watercress is no lightweight. It’s 19 calories per 100g and is 93.3% water. However, it has: Protein: 2.2g; Fat: 0.3g; Carbohydrate: 3g; Fiber: 0.7g; Ash: 1.2g; Calcium: 151mg; Phosphorus: 54mg; Iron: 1.7mg; Magnesium: 0mg; Sodium: 52mg; Potassium: 282mg;  A: 2940mg; Thiamine (B1): 0.08mg; Riboflavin (B2): 0.16mg; Niacin: 0.9mg; C: 79mg. Recipes below.

There are actually several “watercress” in North America you might want to investigate. They include: Barbarea vulgaris, Barbarea verna, Cardamine bulbosa, Cardamine pensylvanica, and Arabis alpina.

Nasturtium” means literally “twisting nose” and was the Roman name for peppery watercress.  Officinale means it was approved in ancient Rome to be sold as a food or medicine in special stores. The Greek name for watercress, Nerokarthamon, broadly translated, means “able to tame Nero’s mind.” It was thought in ancient Greece Watercress could cure insanity.

 Watercress Soup

In this recipe, freshly harvested watercress is cooked with potatoes, chicken stock, milk, onions and garlic to make a deliciously light soup.  To ensure the watercress retains its tender crunch, add it to the soup last. If you wish, you could also blend all the ingredients for a smoother soup.

* 1 medium white onion, diced

* 2 cloves of garlic, crushed

* 1 Tbsp of butter & 1 Tbsp of olive oil

* 2 cups of organic chicken or vegetable stock

* 2 cups of milk

* 2 tsp of sea salt

* 1/s tsp of freshly ground black pepper

Preparation:

1. Heat the butter and olive oil in a pot over a medium heat. Add the onions and sauté for 30 seconds. Turn the heat to low and sweat the onions for 15 minutes. Stir them occasionally to ensure they don’t caramelize. 2. Turn the heat back up to medium-high and add the garlic. Fry for 30 seconds. 3. Now add the potato cubes, salt and pepper and fry for 1 minute. Add the milk, the stock and stir. 4. Let the soup simmer for 10 minutes. Add the watercress and stir well. Turn the heat down sightly and simmer for 5 minutes. 5. Add a pinch of black pepper and serve immediately.

Green Deane’s “Itemized” Plant Profile

IDENTIFICATION: A coarse, many branched pungent member of the mustard family with deeply divided compound leaves, low-growing, dense in suitable small waterways. It has the customary four-petaled flower of the Brassica family, white petals, and seed pods on stems. It grows in the same location and time of year of young water hemlock. Pick carefully.

TIME OF YEAR: January to March in Florida, spring though fall in some temperate climates.

ENVIRONMENT: Likes to grow in clean, running water but not rapids.

METHOD OF PREPARATION: Raw or cooked. Wholesome water is hard to find so cooked is the preferred way. Prepare like any mustard green.

 

HERB BLURB

Research supports traditional views that watercress has medicinal applications. Herbalist use it as a stimulant and diuretic, research suggests it has antioxidants, the ability to lower some blood lipids, and to prevent or treat cancer, particularly that of the lungs.

Chestnuts Roasting… Sequoias of the East

22 December 2014

Chestnuts have done more than just disappear from the landscape: They have dropped out of our lives save for a token appearance at Christmas. Whether in Eurasia or North America chestnuts were a major staple. Long before the cultivation of wheat entire European populations lived off chestnuts as later populations would depend on potatoes. In […]

Roses

15 October 2014

I’m not sure I found wild roses or they found me. Growing up in Maine the local soil was usually either ground-up glacial sand or clay which is decomposed feldspar, or ledge. Not much of a choice if you’re a plant. We had sand, over ledge with a thin veneer of topsoil. And in that […]

Chokeberry: Bushy Health Food

22 August 2014

It’s a long ways from the mountains of Maine down the Appalachian Trail to the mountains of western North Carolina. It is also a long ways from ones 20’s to ones 60’s. These distances revealed themselves recently when I notice a plant while hiking in the Smokies. It was familiar but not familiar, a wrong […]

American Lotus: Worth Getting Wet For

21 July 2014

 More American than apple pie Nature fights back. Much of Florida is giving way to housing. For several years I passed a large abandoned pasture with a dry lake bed. Then it was developed into a subdivision and the lake watered again. For a while very little seemed to grow in the lake and then […]

Chickasaw Plum: Yum

Can We Eat Grass?

That simple question has a complex answer: Yes, no, and maybe.  It’s a topic I explored in a recent Green Deane Newsletter and the basis for this article. Strictly speaking we eat a lot of grass, but in the form of grain: Wheat, rice, rye, barley, millet, sprouts et cetera. What most folks want to […]

A Pitch For Spruce Gum

29 December 2013

Real spruce gum is not easy to chew. It is not soft or sweet. Hard and crumbly is more accurate along with pieces of bark and bits of insects. But if you have good teeth and patience it will in time become a stiff gum. And if you leave it on your bedpost over night […]
