Figs

The Wikipedia says that there are about 850 species of figs. However, in another article, it also says that the plant that we use is the common fig, Ficus carica. Most of my knowledge of this plant comes from that article.

Figs have been cultivated by humans since about 9,000 B. C., and may have been the earliest cultivated plants. The first evidence for this comes from the Gilgal archaeological site, which is near Jericho.

Figs may be eaten as they are, or made into jam or preserves, or dried. They don't keep well for transport, so are often sold as dried figs. One form of dried figs is fig newtons.

The fruit is sweet, all right. Nearly 48% of a fig's weight is carbohydrate. The good news is that less than 1% is fat. The fruit is almost 10% fiber, by weight. They are a good source of Calcium and flavonols. As some of you probably know, they have a laxative effect.

Perhaps the most interesting aspect of fig life is the way in which fig flowers are fertilized. In the first place, what we think of as a fig fruit hides the flowers, which were, presumably, inside the green fig shown above in the photo. So how are they fertilized? There are wasps, fig wasps, which live inside these fruit/flowers, and move from one to another, pollinating as they goes. In fact, the Wikipedia on fig wasps says that we may be eating wasps when we eat figs. Apparently the wasps are very small. For more on this topic, including photos, see here.

There are videos, from PBS, available here, and here (several segments of an originally longer video). I am not clear as to whether the fig shown in these videos are the figs we grow and eat.

This post is on many of the times figs are mentioned in the Bible.

Thanks for reading!
