Plant Story - Garlic, Allium sativum, the Great Protector

My kitchen is never without garlic. Is yours?

What is this plant that is essential in cuisines from France to China?

Garlic (Allium sativum, amaryllis family, Amaryllidaceae) is thought to be native to central Asia but at least 5,000 years ago it was carried all over Eurasia--to the Middle East, India and China and then Southeast Asia, Africa, Europe and, eventually, the New World. It became an essential part of the diet everywhere it went, to the dismay of those who do not like it.

Garlic is a small onion-like plant that grows well in many climates and soils. That was a critical characteristic for its conquest of the world. Furthermore it reproduces several ways, from seeds but also asexual bulbs formed at the top of the plant to scattering the little bulbs that we eat (garlic cloves) which form just above the roots. Combined these allow rapid, easy reproduction. And spread. It has naturalized in many states in the U.S. (link) and is classified as a noxious weed  in Arkansas.

The name garlic is an old English (or maybe older, German) combination of gar (from gare, a spear) and leac (a leek and more generally a pot herb), referring to the spear-shaped leaf.

The strong sharp oniony taste of garlic is certainly why it is included in foods. But tightly linked to that is garlic's role as a medicinal plant. Traditional cultures used it for a very long list of ailments, from curing asthma to settling the stomach to treating sprains to inducing sleep, to warding off scorpions and snakes and a lot more. Since the beginings of modern science, garlic has been shown to be a highly effective antibiotic.

Highlights of the history of garlic as a medicine include the recommendation to eat a clove of garlic every day--it was considered a potent preventative medicine. It was heavily used in the First World War and, in the Second World War, on the Russian Front as an antibiotic and antiseptic. From those uses come its nicknames, "country man's treacle" (treacle was a sugar syrup used to cure everything: sugar was much more expensive than garlic in Europe until quite recently) and "Russian penicillin."  Its use as a medicine declined since the advent of penicillin but it is still an effective an antibiotic, with other verified medical uses. I refer you to medical sources for more on it as a medicine (web md  consumer reports) and to cookbooks for its use in food (BBC, video).                      

Since it was known to everyone, garlic has lots of folklore.

Garlic was associated in ancient Greece with the goddess, Hecate (link, link). Goddess of the underworld and magic, Hecate could be kind but she commanded powerful evil forces. Offerings to her were prudent. She was frequently portrayed at building entrances, crossroads and other places where you might encounter dangerous strangers. Garlic was among the offerings considered appropriate.

If a mean spirit threatened, you could protect yourself by biting into a clove of garlic and throwing it as far as you could. The garlic would take the spirit with it.

Garlic was worn to protect from evil generally but especially against the plague. Lots of plague survivors gave credit to the garlic.

Mountaineers wore garlic for protection from foul weather and monsters. Korean travelers ate garlic to ward off tigers.

Sailors took it with them aboard ship to protect the ship.

Brides carried a clove of garlic during the wedding for good luck and ward off evil. Garlic was put into the cradle to protect the baby.

In England and North America, slices of garlic were put into children's shoes, against the sole of the foot, to protect them from whooping cough.

Warding off vampires with garlic appears to have developed as a story in the last couple centuries, as writers embellished eastern European folktales of human vampires (Live Science on vampires link). Given garlic's long history warding off evil, this was a logical choice.

It had serious detractors:

Culpeper warned that in choleric men (ruddy, hot tempered) it worstened the condition; in melancholy ones (cold, depressed), garlic provoked strange fantasies and visions.

Evelyn, writing in 1699,  asserted eating garlic had previously been a punishment for "the horrid'st Crimes."

On the other hand, eating garlic was supposed to increase courage and the willingness to fight, according to the Greek playwright Aristophanes and to Roman gladiators.

Garlic would give you an advantage in a race, either by eating it or hanging it from your horse where the smell would discourage the other horses.

Clearly it is a good plant to keep in the kitchen and grow in the yard.

Parks and Wilderness, Access and Overuse

Rocky Mountain National Park

Rocky Mountain National Park
Recently, the Denver Post published a long article on the National Parks, emphasizing that visitation is up, resulting in very heavy use that is hard on vegetation and wildlife, overcrowds parking lots and creates traffic jams. (Link National Parks Crisis, Nov.  21, 2018: I don't know if you can see it without a subscription but on The Guardian's website I think its accessible link; National Statistics link). Many of the problems can be solved by investing in infrastructure, but not access to solitude. It is harder and harder to have a wilderness experience.

Plants on Walls

Sticking potted plants with interesting colors and textures of foliage or flowers into niches in a wall is a recent, stylish form of decoration, often called "green walls."

Sometimes it works, but I see it generally as plant abuse.

Homogenized World--Tropical Plant Distributions

Caribbean beach

I am writing a novel about Paraguay in 1630--because when I saw northern Argentina and Paraguay in the 1980s I was surprised by their natural history and history and have wanted to share their stories.

In trying to bring the 17th century to life, I have to describe what was there and that has been quite an adventure because there has been so much change.

Beginning in the 1500s, conquering and colonizing, European powers carried useful plants all over the world. To describe our world early in that process, I have to figure out what plants are native to the Americas and which were introduced. If it is native to the Americas, it will likely be new to Europeans. If it is from Africa or China, it may not yet be common in South America even if it is abundant there today.

Winter Escape--Honolulu

As the days get colder, I daydream about tropical beaches.

For example, in Hawaii
Waikiki, Honolulu

While I always recommend the Big Island if you are going to Hawaii (for its diversity and its active volcano) I recently did a successful experiment--I had a great botanical time from a single hotel in a easily-reached city. We simply flew to Honolulu last May, stayed in a hotel there, and explored from there.

Winter Escape--Costa Rica

Beach, Costa Rica
The days are getting short and the wind is chilly. So I daydream about sunny warm places.
For example, Costa Rica.

I had never been in the tropics when I went there in 1972. It was magical. I have been back five times since.  It remains wonderful.

Plant Story--Papaya, Tropical American Fruit

papayas for sale
You see them sometimes in northern markets, green-orange fruits looking like small footballs. And I presume sometimes they taste pretty good.

But pretty good is not how they taste in Florida or Hawaii or Costa Rica. A really fresh papaya is a marvelous thing.
