The Common Fig, Ficus carica, the First Cultivated Plant.

The story of the common fig, Ficus carica,  needs more than one blog.

I started writing about the common fig in my last blog- The common fig, Ficus carica, Fruit, Flower or Carnivore? As I uncovered its story I realized that it would take more than one blog to share its long and complex history.  I illustrated the common fig, Ficus carica, several times for the “Digging In” gardening column of the Washington Post. This week I post a botanical illustration of Ficus carica “Negronne” to illustrate this entry. This natural dwarf variety can be grown in containers and is particularly suited to the Pacific North West, where I live.

The common fig, Ficus carica, and the first farmers.

It seems everything I read currently brings me back to the first farmers. Recently while reading about the Burren region in the west of Ireland I learned how the first farmers impacted that environment, using only a simple axe as their main tool. Then, while researching the common fig, Ficus carica, for this blog, I discovered that it was probably the first plant cultivated by humans: predating the Neolithic farmers’ “eight founder crops” -einkorn wheat, emmer wheat, lentils, chickpeas, barley, flax, bitter vetch, and peas, Wikipedia– by many centuries.

Neolithic Farmers.

The Neolithic period (starting c. 9500 BCE) marks the beginning of farming and the common fig comes from the region where farming began, the Middle East. Common fig subfossils found in the Neolithic village of Gilgal 1, 13 Kilometers north of Jericho (present day West Bank,) date from 9400-9200 BCE.

Parthenocarpic figs and human selection.

This first fig crop was a parthenocarpic type i.e. the fruit is produced without pollination (see my last blog for more on this subject.) This means that these fig plants were “cultivars” i.e. plants selected and propagated from cuttings by humans rather than grown from seed. We have been growing and eating figs, as well as introducing them to different parts of the world, for over 12,000 years. Parthenocarpic varieties helped this spread because they don’t need a local insect to pollinate the plants in order to produce fruit.

How much do I know about the food I eat?

Reading about the common fig makes me realize how little I know about the food I eat. I’m not talking about which farm my food comes from, whether it is organic or conventional, what variety it is, or how far it has traveled to reach the grocery shop’s shelf. Rather, I am talking about food’s cultural history. I wonder what it means that we have been eating figs since the end of the last ice age? What a long human-plant relationship this is. Have we co-evolved together?

Plant or human selection?

In my last blog I also wrote about the high nutritional value of figs, especially in relation to our human needs. Is this just a happy coincidence? Science may explain the selection and success of figs as a food crop through a mixture of human interference and natural selection but I wonder if those first farmers choose the fig knowing how nutritional it was to eat or just because it tasted good? Or, could it be, as Michael Pollan suggests in his book The Botany of Desire, that the common fig chose us to guarantee its survival?

Agriculture- from Neolithic times to today.

Agriculture has come a long way since Neolithic times. The highly intensive form that we now practice, with its heavy dependence on chemicals, limited selection of crops grown in vast monocultures and enormous use of fossil fuels and other natural resources to produce the crops, is a far cry from those early days. I imagine those first farmers, mostly women undoubtedly, scratching their heads in amazement. Learning about the common fig’s story raises my awareness of our dependence on nature to sustain us: the long and critical relationship we humans have with the plant kingdom- the source of most of our food- and the role this small fruit has played.

The Common Fig, Ficus carica, unwelcome bounty!

I originally started writing about the common fig, Ficus carica, because of my annual battle with it. Our neighbor’s fig tree leans over the fence onto our yard and rains its bounty of figs onto our vegetable garden every year.  Unfortunately, neither I nor my husband or daughter eat figs. I find them too sweet, preferring fruit with a more tangy taste. Every year I spend hours cleaning up semi-rotten figs after they have smashed their way through our tomato plants before embedding themselves, like small, sticky bombs, into the mulched paths. Then the clouds of fruit flies follow. It is not one of my favorite gardening moments in the year.

Coming to terms with the common fig.

Even though I don’t like to eat figs I do feel guilty that I am allowing this food source to go to waste. I ask friends and neighbors to come and pick but to date no one has taken me up on the offer. In an effort to come to terms with this dilemma I started researching the common fig. Maybe knowing more about the plant would help me change my attitude and even motivate me to eat some of them or make more of an effort to pass them on to others at least.

I have illustrated the common fig several times for the Digging In gardening column of the Washington Post. Both times I used my neighbor’s tree for reference. I love drawing botanical illustrations, regardless of the subject, especially when I can use a live specimen, and there is no shortage of live specimens of fig in my garden!! I feel I owe this tree something seeing as it has helped me out in the past.

The common fig, a fascinating story.

Once again I start researching a plant and find myself drawn into a long and intriguing story that brings me all the way back to Neolithic times and the first farmers. By coincidence I am reading a book at the moment that has spurred on my research- The Fruit Hunters, A Story of  Nature, Adventure, Commerce and Obsession. This book by Adam Leith Gollner is a great read and even if you have only the slimmest interest in plants you will find it full of great stories to edify and entertain.

Too good a story for just one blog entry.

The story of the common fig, Ficus carica, is a complex and multi-faceted one that merits a book or indeed a series of books. There are two aspects of the fig’s story that have delighted me and sent my imagination into over-drive.

1. The reproductive cycle of the fig and its pollination strategies.

2. The first farmers (Neolithic) who domesticated the fig.

For this reason I’m writing two blogs on the subject starting with the reproductive cycle of the fig and its pollination story.

A fruit that is not a fruit!

I should write ‘false fruit’ or ‘multiple fruit’ when referring to the fig because what we eat is in fact the flower or inflorescence (an arrangement of multiple flowers.) The fig ‘fruit’ is a flower turned inside out: its juicy, red interior made up of lots of individual flowers and seeds growing together. The pollinator, a small female fig wasp that depends totally on the fig for its life cycle, must enter through a small opening in the fig, loosing her antennae and wings en route, to lay her eggs on the female fig flowers.

Fig tree pollination-well, sometimes?

Before all you fig lovers start spitting out your figs let me reassure you. Figs have several ways of producing fruits and most of the varieties in our gardens (Adriatic, Black Mission, Brown Turkey, Brunswick, and Celeste) are self-fertilized i.e. parthenocarpically. This means that they do not need pollination to produce their fruit.

Carnivorous figs?

The fig varieties that are pollinated by female wasps (e.g. Calimyrna, Marabout, and Zidi) consume the wasp after she has done her job laying her eggs and pollinating the flowers (Does this make the fig a carnivore?) When these eggs mature into female and male wasps the males (who are wingless) mate with the females and chew a tunnel through the fruit creating an opening through which the female wasps can escape. This suggests to me that the wasps may have left the fruit to find new fruits to pollinate before the fig is eaten but one account I read said that we eat the wasp’s eggs with the fruit- extra protein for us all?

Great nutrition- keep eating your figs.

I hope my account of the coevolution of the fig and fig wasp and their symbiotic relationship doesn’t put all you fig lovers off your figs, but rather fills you with the wonder and awe that nature continues to inspire in me? Who needs science fiction when we have nature all around us. I do eat dried figs and now that I’ve learned what a nutritious food it is, I plan to eat more. According to Wikipedia, figs are one of the highest plant sources of calcium and fiber and USDA research on the Mission variety found that dried figs are richest in fiber, copper, manganese, magnesium, potassium, calcium and vitamin K, relative to human needs. They also contain many antioxidants.  So keep eating your figs and maybe I’ll figure out a way to dry some of my neighbor’s next year.

A Well-Travelled Exotic Insect- The Brown Marmorated Stink Bug.

A ‘botanical’ illustration that walked into my blog.

All my blogs so far have been about my botanical illustrations. This week however, while continuing to write on the theme of fruit and vegetables, I write instead about an insect. This one appeared in our bathroom a few weeks ago. It left such an impression that I had to write about it. I have illustrated many insects for the “Digging In” gardening column of the Washington Post. Most of them have been garden pests but not all. This insect, above, is definitely a pest and has the potential to become a serious problem for fruit growers.

A stinkbug!

The mottled brown, six-legged creature, sporting dark antennae with white bands towards the tips, is only three quarters of an inch in length but hard to miss on our white linoleum floor. I immediately recognized it as a stink bug because of its shield-shaped body- they are also called shield bugs. My first thought was; how on earth did it get into our upstairs bathroom? Later I learned that this species takes shelter in houses over the winter.

We have a very permissive attitude towards insects in our house, with only a few of the usual exceptions. After all, we live in an old house full of nooks and crannies and very attractive to insects. Usually I, or my daughter, carefully release any tiny visitors to the outdoors.

The Brown Marmorated Stink Bug.

When I saw the stink bug I called my daughter so that she could have a good look. Then she gently lifted it onto a piece of tissue and released it outside onto our front porch. I didn’t think much of it at first. All insects are interesting and worth a second look but something about this one made me pause. It nagged at the back of my mind for a few days before I finally remembered that I illustrated a pest stink bug just like it for the “Digging In” gardening column a couple of years ago and then I remembered it’s name- the brown marmorated stink bug.

A potentially serious pest.

Of course the “Digging In” gardening column deals with gardening queries from the Washington D.C. area and not the Pacific North West. I didn’t connect the two stink bugs at first. I assumed this couldn’t be the same species all the way across the continent but rather a native species. I ‘googled’ the brown marmorated stink bug anyway. There are lots of photographs on line. I saw that our house visitor looked very similar. As I read on I felt rather guilty because I learned that we might have released an exotic, potentially serious pest into the neighborhood.

When a second one appeared in our bathroom a few days later I was ready with a jam jar and called the local extension service almost immediately. I brought the stink bug to their office and they confirmed that it was indeed a brown marmorated stink bug. However, they alleviated my guilt somewhat by letting me know that it was not the first found in the area.

A stink bug far from home.

The story of the brown marmorated stink bug is an interesting, cautionary tale. It was first found in the U.S.A. in Allentown, Pennsylvania in 1998. No one knows how it got there from its native range in China, Korea, Taiwan and Japan but it is presumed that it hitched a ride in some cargo. It is a pest in its own native range using fruit trees and soy, amongst many other species, as a host plant. The stink bug has sucking mouthparts and feeds by piercing fruit and stems. For this reason it could become a serious agricultural pest, especially here in Oregon: a huge fruit growing state.

Now  found in Oregon.

It was first found in Oregon in Portland in 2004 and later in Salem – where I live. As of today it has managed to find its way to over half the states in the U.S. According to an Oregon Dept. of Agriculture information sheet only two specimens of the stink bug have been found in the Salem area. If this information is up to date this means that the two stink bugs I found may be number three and four. If you think you have seen this stink bug in your house or yard bring it along to your local extension service and have them check it out. If, like me, you don’t like squashing bugs or spraying them with pesticides, an alternative way to kill them is to put them in a container in your freezer for a while.

Bell Pepper, Capsicum annuum- The Only ‘Sweet’ Pepper!

/0 Comments/in , , /by

Bell pepper, Capsicum annuum © Aislinn Adams

Bell Pepper, Capsicum annuum- a Central and South American native.

Continuing my theme of fruit and vegetables I post an illustration of Bell pepper, Capsicum annuum, originally created for the “Digging In” gardening column of the Washington Post. Both hot and mild peppers come from the species Capsicum annuum. Inadvertently I have chosen another species native to Central and South America, like the tomato posted in my last blog, and although we are inclined to think of bell pepper as a vegetable, like the tomato it too is a fruit.

Cultivated in ancient times.

Capsicum annuum has been in cultivation for millennia in Central and South America. According to Roger Phillips and Martin Rix in their book “Vegetables” from The Garden Plant Series, pepper seeds were found in archaeological deposits in Tehuacan, Mexico as early as 7000 BCE and the earliest records of peppers in cultivation are from about 2000 years later.

Christopher Columbus, naming ‘pepper’ and expensive condiments!

Unlike the tomato, when peppers were introduced into Europe by Chrisopher Columbus in 1493 they were accepted quickly as a food plant. Columbus is also credited with giving them the name ‘pepper’. It is most likely that it was the hot type that he brought back first not the sweet, bell pepper. At the time any species with a hot, pungent taste was called pepper after the true pepper, Piper nigrum. True pepper, a native of southern India, was a prized condiment in Europe then and very expensive.  Europeans quickly learned to grind the ‘hot’ pepper species to a powder and use it as a cheaper substitute to true pepper.

Bell pepper and recessive genes!

Bell pepper, on the other hand, is the only member of the Capsicum family of peppers that does not produce capsaicin, the chemical that causes that strong, burning sensation when eaten. This is due to a recessive gene that eliminates capsaicin from the bell pepper, thus making it ‘sweet’. Thanks to this recessive gene we can all enjoy the tangy, sweet taste of bell peppers without having to run for the tissues.
