Discovering the Kei Apple

How I discovered the Kei Apple

I first came upon the Kei Apple whilst wandering around the El Botanico gardens in Puerto de la Cruz on the island of Tenerife in the Canary Islands. I didn’t know it by name then but needed to find out what it was. I was accompanied by my friend Gill and both of us were suddenly struck by a wonderful fruity aroma that filled the warm air. 

We discovered that it was coming from a tree very near to where we were in the gardens. Its branches were laden with fruit and some had fallen on to the ground below. These fruit were golden yellow and reminded me of small apples.

Of course I picked one up and smelled the amazing aroma. I decided to take it home with me in order to see if I could identify it online and find out more about this tree and whether the fruit were edible. They certainly smelled like they should be! I made a note of the Latin name which was Dovyalis caffra that luckily was on a label underneath the tree.

 

More about the Kei Apple

The Kei Apple, which is what the tree we had found was, is actually named after the River Kei in South Africa. This is where the tree grows in the wild and its range also extends up into the neighbouring African region of Tanzania. The Kei Apple is perhaps not commonly known as an edible fruit but the tree has nevertheless been introduced into many subtropical parts including countries bordering the Mediterranean, and the States of Florida and California in the south of the US.

The Kei Apple belongs to the Flacourtiaceae family and the tree is also known as the Umkokola. I think Kei Apple is easier to remember though so that will do for me.

 A small evergreen tree, the Kei Apple has branches covered and protected by spines and it reaches some 6-9 metres in height. It is excellent for use as a hedge when pruned, and this is why it was originally brought to Australia. It is well suited to a hot and dry climate being both drought and salt resistant

The Kei Apple has both male and female trees. They have very small flowers in the axils of the tree’s leaves. According to Wikipedia, some female trees are actually parthenogenetic and can produce fruit without being fertilized with the male tree’s pollen in the usual way. Kei apples can be produced in such great numbers tha they actually weigh down the branches of their parent tree.

The Kei Apple is most often grown from seed, and several of these are produced in each fruit. They can be propagated by taking hardwood cuttings. However, Kei Apple saplings take around four years before they are at a size where they can flower and bear fruit of their own.

The Kei Apple is often cultivated as an ornamental tree for parks and gardens. Its pleasantly aromatic fruit contain vitamin C and although they are edible they are very acidic and are too sour for many people’s palates.

Jams and Jellies

Kei Apples can, however, be used to make delicious jams and jellies, or as an ingredient in chutneys. The apples can be eaten raw but, as already noted, many people find they taste far too sharp. Sugar or honey can, of course, be used to sweeten the fruit.

Winter drought on Mt Teide. January 2012

Tenerife is still suffering an ongoing drought having not had anywhere near the normal rainfall last autumn or in  the winter months. The island depends on the storms that normally occur at these seasons to fill up the reservoirs and small number of ponds and to soak the ground so the plants can all grow. It simply didn't happen this time around.

Here I am filmed up on Mt Teide, the highest mountain in Spain, in January 2012, talking about the terrible state of the highland vegetation there. Much of it was dying or dead and crumbled to dust in your hands.




The media here for some unknown reason failed to report on this climatic disaster until over a month later. People I spoke to that live on the island thought I was making too much of a big deal about this. They told me it would rain in February and all would be OK. It didn't!

My report on the unusual winter drought was published in Tenerife News, making me, as far as I know, the first serious news report on the subject. Since then a few other news stories have gone out about the problem. It is sad that it is the worst winter drought in 50 years.

Apparently sometimes you get no rain or very little in the autumn and early part of the winter but then in the New Year the thunderstorms arrive and make good for the lack of rain until then. It is very unusual for there to be no rain in the autumn followed by none in the winter too!  This is a very serious problem, not only for farmers, but also for much of the varied and unique flora and fauna of the island of Tenerife.

Because Mt Teide is so high the rain falls as snow up there. It is usually capped in gleaming white from November onwards, sometimes as late as may of the following year but not this time. The one place you can normally count on having a White Christmas in the Canary Islands didn't have one, and visitors to Tenerife over the winter months did not get to see the majestic mountain arrayed in a white mantle that can be seen easily from the windows of planes approaching the island.

The unique, and in some cases, very rare plants that grow high on Mt Teide may well be drought resistant to cope with the extreme climatic conditions experienced up there but they are not adapted to withstand drought for this length of time. They normally get a very hot and dry spell in the summer but this is followed by autumn rains that help to rejuvenate them but sadly these rains never came.

 Ponds in the village of Erjos that usually fill up in autumn and winter with enough water to carry them through the summer months did not get their seasonal top up. These ponds, which form a unique wildlife haven for water birds, frogs and aquatic insects such as dragonflies and water-beetles, were drying up as early as March. Even tough vegetation like brambles that grow around the ponds have suffered very badly and are dried up and gone brown in the heat. Where tadpoles could normally be seen in large numbers a cracked and barren expanse of dried mud baking in the sun meets the eye.

It is impossible to say how badly hit the wildlife of the island has been by this drought and we can only hope and pray for some equally very unusual summer rainfall, and as much as possible is wanted, if not by the tourists, but by the farmers and the animals and plants that live on the island.

Edible plants: Mallow

Tree Mallow

Many people today are becoming increasingly interested in foraging and finding out what edible plants are out there that we can safely gather. There are many books and videos on the subject available and anyone that knows much about the subject would I am sure agree that it is vitally important to be able to identify the plants you can eat and to avoid those you cannot. There are wild flowers out there that can make you very sick and some that can actually kill you. So this is why identification of an edible species is so important.  Fortunately there are many common plants that are very easy to find and that are difficult to mistake for poisonous ones. The Mallows come into the common and safe to eat category.

Marshmallows are very popular sweets but what you probably don't know is that they are named after a wild flower, the roots of which were once used to make a confection. Actually many plants in the Mallow family (Malvaceae) are edible and many have properties that make them useful in herbal medicine too.

The leaves of the Common Mallow can be cooked like spinach greens and the flowers are edible, as are the roots that ban be boiled and eaten. Most plants in the Mallow family can be eaten and some have been used in recipes in different parts of the world. The leaves cook well in soups and stews and because they contain vitamins and minerals are a nutritious ingredient to add.

Edible plants: Fennel

Fennel in bloom

Fennel with its aniseed aroma and feathery foliage has got to be one of my favourite herbs. It grows wild in Tenerife in many places too and I can't pass by a clump of the plant without being able to resist eating some of its fresh leaves or the very tasty seeds. I simply cannot end up crushing some of it up in my hand and inhaling the wonderful perfume. I love Fennel!

Fennel is one of many common wild flowers that is edible and nutritious. It is a herb that foragers would look out for. Of course, when gathering wild plants to eat or use in herbal medicine it is vitally important to be able to identify those that are safe to consume. There are some plants out there that can make us very sick and some that can be lethal. Some relatives on the Fennel in the Apiaceae or Parsley family come into this dangerous category. Fools Parsley and Hemlock are tow of the deadly ones.  Fortunately Fennel is very easy to identify. It has a distinctive aroma that poisonous plants that look a bit like it do not have. That is one way of checking if you have found a true Fennel: crush some of the leaves or flowers and see if there is a pleasant perfume that reminds you of Anise.

Fennel grows on waste ground, in grassy places and by the sea. It is often found in large clumps and its fine feathery foliage and tall flowering stems are what to look out for.

Frogs need saving too

I have loved frogs ever since I was a little boy so the news that they are disappearing is very sad to hear. Fortunately a charity has been set up in America called Save The Frogs, and as its name suggests, it is all about frog and amphibian conservation.
As many as a third of the frog species in the world are endangered and some types have already become extinct. The frogs are dying out due to a combination of lack of habitat, water pollution, a deadly chytrid fungus disease, predation by invasive species, over-collection by humans and Climate Change. Pesticides and herbicides like Atrazine and Roundup are taking a heavy toll. Many frogs get run over by heavy traffic on roads that the animals have to cross to get to and from their spawning sites.
It is really sad to know that these amazing animals are dying out in many places, often due to human behaviour that is destroying the habitat of these amphibians. Conservationists are working on saving the frogs but a worldwide effort is really needed.
All children love to see tadpoles and to watch the amazing transformation into tiny froglets. Frog spawn and tadpoles used to be such a normal thing to see in ponds in parks, gardens and the countryside but sadly this is no longer the case in many places. Something must be done to give the little creatures their chance at survival.

Tenerife News of the environment that doesn't get reported

Tenerife News media are not reporting much about a number of environmental issues affecting the island. The worst problem is the ongoing drought that is drying up everything and killing vegetation that shrivels in the heat.  Ponds are dried up or in the process of drying up and reservoirs are very low. Unless the island has heavy rainfall soon this will mean disaster for farmers. In Erjos, where the ponds are a real haven for wildlife, most of the water has dried up leaving cracked and caking mud to bake in the heat. Water birds such as Coots and Moorhens will have to fly away in search of a new home unless the rains fall soon.

Besides the drought problem, pine forests are losing trees killed by bark beetles and the island's Dragon Trees are under attack by a species of scale insect. There are dead and dying trees to be seen all around the island. This is a sign that all is not well at all, and yet so few people seem to notice or care and the local media is not reporting these matters.

Tenerife relies on tourists coming here and a main attraction that the island offers besides the sunshine and beaches is its incredible countryside. The forests are a big part of this but Canary Pines are under attack and many are dead. Bark beetles are killing them and others were severely damaged by approaching hurricane force winds that battered Tenerife back in the winter of 2010.

Teide Violet and other endangered wild flowers found on Mt Teide

Tajinaste Rojo (Echium wildpretii) Photo by Steve Andrews

Tenerife's Mt Teide is the highest mountain in the Canary Islands, and the highest mountain in all of Spain. Its very great height and volcanic nature have created unique environments in which some very rare plant species grow.

The Tenerife highlands are a real paradise for botanists who can hunt for rarities on the slopes of the mountain and the rocky scrub-land that is exposed to extremes in temperature and sunlight. Mt Teide usually has snow on its peak in winter, though none has fallen this year so far in the ongoing drought. Extremes of heat and cold and the very barren volcanic terrain offers a very unique habitat for the flora and fauna that live high on the mountain ranges. It can be freezing by night and baking hot by day and yet there are mammals, birds, reptiles, insects and many wild flowers and shrubs that live on Mt Teide's highlands.

Some plants such as the Teide Violet (Viola cheiranthifolia) and the Red Viper's Bugloss (Echium wildpretii) or Tajinaste Rojo are not found growing in the wild anywhere else in the world. These are two of the endemic rarities that can be found on Mt Teide. The Teide Violet is found very high on the mountain where no other plants are growing. The Red Viper’s Bugloss grows at lower levels near the Tourist Centre and hotel as well as by where the cable-car leaves from. This unusual flower, with its tall flowering spikes of red is often photographed and is the subject of paintings of Mt Teide.
