Pearl Plant

The distinctive yellow flower stalks and the pearl-like fruit of this desert shrub make it easy to recognize and remember. The pearl plant (Ochradenus baccatus) is quite common in the region and are spotted often on my wanders in the wadis near Dahab. In the springtime, they are buzzing with flying insects – bees, wasps, flies, hover flies, beetles, and more I’m sure. This shrub has been reported as one of the most important food sources for many animal species.

There’s one species in particular that the plant has a special relationship with – the Egyptian spiny mouse (Acomys cahirinus). The fruit – a fleshy, juicy berry – is attractive to desert animals. But when an enzyme in the flesh of the berries combines with what’s inside the seed, it creates a toxic “mustard oil bomb”, deterring most animals from munching on this fruit (and destroying the seeds in the process). The spiny mouse has adapted to this, however. They will collect fruits and bring them to a different, rocky area, one that is safer for them. There, the mice chew and eat the flesh, careful not to bite the seed which they then spit out, avoiding any nastiness and helping to disperse the plant’s seeds. One study suggests these safer places the mice choose are actually “the best places for young O. baccatus plants to germinate, grow and survive.” How’s that for some symbiotic behavior!

The Bedouin of Sinai have also found benefits of the pearl plant, using it in traditional medicine to cure joint pain. A bowl of water in which the leaves have been boiled is placed in a hole in the ground above which a makeshift tent is constructed. The patient then lies beneath its cover for 24 hours. Pearl plant is also used to cure aches and pains in a camel’s body except instead of boiling the leaves, the plant is placed on embers in a hole. In Saudi Arabia, the plant is used to lower blood cholesterol and to counteract malaria.

Recently, a friend and fellow plant-lover asked me if this species had separate male and female plants as she had noticed that some plants were full of berries, while others only had a few. In dioecious plants, only the plants that grow female flowers produce fruit. Date palms are a good example. It turns out, though, that the pearl plant is gynodioecious, meaning that some plants have only female flowers and some plants are bisexual, having both male and female flowers. This explains the phenomenon my friend noticed – two plants, side by side, both in full bloom but only one seeming to fruit fully.

I’ve always liked this plant’s Latin name, Ochradenus baccatus. Ochradenus comes from the Greek for “pale yellow” or “yellow ochre”, and baccatus means “adorned with berries”. It is also known as taily weed and shrubby or sweet mignonette in English and is called gurdhi by the Bedouin in South Sinai.

The Third Edition is Here!

I’ve had many requests over the last couple of years for print copies of the guidebook. I decided that if I was going to print more, the book should be the best, most up-to-date version possible. So that’s what I’ve been working on, updating the book. It’s been four years since the printing of the second edition, and eight years since the first. I continue to discover and learn about the desert plants and so, to this third edition of the book, I have added 13 new plants (for a total of 155) and 90 new or additional photographs for the plants previously included.

And now I finally have a limited number of print copies available of the third edition of Wandering through Wadis: A nature-lover’s guide to the flora of South Sinai!!

The book is printed on thick quality paper bound with spiral wire 2 cm round. The book is 21 cm x 14.5 cm, about A5 paper size. It weighs 518 grams. Something to consider when deciding if you would want to carry it with you on hikes.
A bonus to reading the eBook version, especially on a tablet, is that you can easily zoom in on the photographs of the plants.

Also, depending on your device, it may weigh less than the print copy. My tablet, in a case, weighs 400 grams (100 less than the print copy).
One useful feature of the PDF version, especially when read on a laptop or PC, are the bookmarks that help you easily navigate through the book.

You can download a sample of the book as a PDF file for free here . This requires an email address. If you’d rather not enter an address, click the ‘Preview’ button on the top of this page to view the file online.

Print copies cost LE 400, including free delivery in Dahab. Shipping is possible within Egypt. Send me a message to arrange purchase and delivery of your copy.

The eBook version has also been updated and can be purchased online for $8 here. Contact me if you would like to arrange alternative payment and delivery options. Enter code WADIBLOG for a 10% discount.

Happy Wandering!

Stagshorn Lavender

Many people are surprised to learn that lavender grows in the desert wadis of South Sinai.

Stagshorn Lavender (Lavandula coronopifolia) is one of 47 lavender species in the Lavandula genus and one of two that are native to Sinai. While not as fragrant as its cousins, the leaves of Stagshorn Lavender do have a pleasant scent and are edible, grazed by the local herds of goats, sheep, and camels.

And I can attest to their tastiness! When I had a plant growing in my desert garden, we often added the leaves to our salads.

It is in fact their distinctively branched stems that gave this species its common name – stagshorn. In Arabic, this plant is known as zeiti, diktae, or netash.

Stagshorn Lavender is a small shrub in the mint family and can grow up to one meter in height. Lavandula coronopifolia grows in open rocky habitats, desert plains, and foothills and is the most widespread species of lavender across northern Africa.

The flowers are sky blue to lilac in color and bloom between January and April.

Which means you can seem them in bloom right now! When I was wandering through wadis last weekend, the lavender plants were one of the few plants with flowers. There would be more if the area had received more rain this season, so my fingers are crossed that the small chance of rain forecast for tomorrow comes through!

You can find Stagshorn Lavender – and over 140 other plants – in my book, Wandering through Wadis: A nature-lover’s guide to the flora of South Sinai. Purchase a PDF copy online here.

Wild Mustard ~ Jahag

During the recent Christmas holidays, I spent a day with my family on a desert safari near Wadi Arada. This area has already been blessed by winter rains, so I was thrilled to see some of my favorite plants already sprouting – and in bloom!

This is a type of wall-rocket (Diplotaxi acris), a wild mustard in the cabbage family, called jahag or yahag by the Bedouin. It is one of the species that appears shortly after seasonal rains in desert plains.

It is an annual plant with alternate, serrated-edged leaves that grow out from the base in a rosette formation. The leaves are juicy and peppery-flavored and make a tasty addition to a fresh salad. Of course, the goats, sheep, and camels like to graze these greens as well.

The four-petaled flowers, also edible, are white to pinkish-purplish in color. There is a related species in Sinai, Diplotaxi harra, that has yellow flowers.

Have you ever seen jahag on your desert adventures? Have you ever tasted it?

The Second Edition is Finally Here!

Wandering through Wadis 2nd Edition COVER

I’m thrilled to announce that the updated edition of Wandering through Wadis: A nature-lover’s guide to the flora of South Sinai is ready!  It’s been four years since I published the first edition and I’ve spent a lot more time wandering, photographing, researching, and learning. I was able to add over 35 new plant species to the guidebook, bring the total number of plants in the directory to 142. I also added dozens of new and better quality images of the first-edition plants. The completely revised introduction now includes information about plant biology and the adaptations that desert plants employ to survive the harsh climate of Sinai, highlighting the fascinating lives of desert flora.

The Second Edition is available solely as an ebook. I have no plans at the moment to produce a print edition. I understand the love of paperbacks and the ease with which we can toss them into our backpacks, but the cost of paper and ink has doubled over the last year, as Egypt imports nearly two-thirds of what it needs from abroad. My book has over 170 pages and 450 photographs. That’s a lot of paper and ink. So, for now, it’s an e-version, a PDF file, which is easily read on tablets, iPads, laptops, and PCs. There is one bonus of reading the book on a device at least – the ability to zoom in on the images.

Happy Wandering!

Foraging with Friends

A memory popped up on my Facebook page today and it’s one of my favorites, so I thought I’d share it here. This post was originally published on May 6, 2014 on Bedouin History Desert Safari’s blog.


It’s spring – my favorite time of year in Sinai! Especially after a particularly wet winter since that means our desert plants are thriving and the goats and sheep have plenty to graze. Recently, we met Freyj, one of Bedouin History’s drivers and guides, at his daughter’s springtime camp in the desert. We were welcomed with smiles and a light lunch of fresh bread and goat milk. It didn’t take long for the children to wander over to see their grandfather and his foreign friends. Freyj knows well my passion for plants and photography and knew I would be eager to explore the surrounding desert. Recalling our failed attempts last year to locate one of the edible plants, Zeinab, one of Freyj’s young granddaughters, eagerly offered to get her digging tools and lead our exploration. So we set off with Zeinab, Farah, Mohamed, and Omar to forage for tummayr (تِمِّير), the Bedouin name for Erodium crassifolium.

Known in English as Desert Storks-bill or Hoary-leaved Heron’s-bill, this plant has an edible tuber that grows deep in the ground. But there are eight different Erodium species growing in Sinai so finding the right one involves a knowledge of what tummayr leaves look like and where they grow. All Erodiums have fruit that look like long bird beaks, hence their common English name, but each species has distinct leaves.

Zeinab and the other children are a wealth of information about the local plants, especially the edible ones, as foraging for these are a favorite past time of the Bedouin children who live in the desert for a few months of the year.

I followed Zeinab through the wadi, trying to keep up with her quick steps and even quicker digging abilities. I try to figure out which Storks-bills are the ones we are looking for and was cheered on by Zeinab when I correctly point out a large tummayr plant.

Zeinab dug quickly, scanning the area to check on the progress of the boys, who are leading their own expedition with my husband. It seems that this had turned into a contest to see which “team” could find the most. But we are all successful and end up with handfuls of edible tubers! The children remove the skins with their fingernails and hand them to us to eat. The small potato-like tubers are sweet and crunchy.

Along the way, the children have also spotted sweet desert onions. They are so quick to dig these up that I never see what the plant looks like when it is still rooted in the earth. The onions, possibly an Allium species, are sweeter and juicier than the tummayr. And easier to reach as they are not buried so deep in the rocky ground.

We returned to camp to share our foraged goodies with the other adults at camp, but they showed little interest in eating our treats. It seems foraging with friends is a childhood habit, something to entertain them during the long days in the desert. How lucky I am to have such amazing young friends!
