This is one of my favorite times of year to wander through the wadis of Sinai. For many reasons. Because of recent rains, the wadis are bursting with tiny green baby plants right now. I always enjoy stopping to discover what plants come up first after the rains, and what they look like when they’re so young. Fascinating! For me. 🙂 Another reason I love this time of year is that the arghel plants are in bloom – and they give off such a delightful fragrance!
Some wadis, like Wadi Kid, are lined with arghel plants (Solenostemma arghel), called harjal in Arabic. If you are lucky enough to walk through one of these wadis in November, it will be a joy for your senses! Often you will smell the flowers before you turn a corner and see the plant.
Harjal is an evergreen shrub in the dogbane family. The plants grow up to 1 meter high and 10 meters in diameter. They live in gravelly, sandy, and rocky soils usually at the edge of wadi beds. Here’s a picture of a large harjal plant growing near Wadi Connection in Dahab:
The leaves are greyish-green and their white flowers grow in bunches. The fruits are purplish-green, oval shaped, and can grow up to 5 cm in length.
When they are ripe, they turn yellow and dry to a light brown. They split open, releasing dozens of tufted seeds that are blown by the wind.
Bedouin in Sinai use this plant for medical reasons, as do many people throughout Egypt. Sadly, this plant is endangered due to over-collection for sale at herb shops dealing in medicinal herbs. Locally, the stem and leaves are used to treat a variety of ailments – infected sores and cuts, coughs and colic.
I’m not the only one attracted to these fragrant blooms! Butterflies, bees, and other pollinators are drawn to the flowers’ sweet nectar. In the picture below you can see two orange Painted Lady butterflies – the species I see most often on the harjal flowers – and a Brown-veined White butterfly.
