Home Grown Exotics

Grow exotic houseplants from fruit and vegetables bought from the greengrocer

There are many fruit and vegetables we can easily buy at the greengrocer’s or the fruit and veg section of the local supermarket, that can be grown as unusual and exotic houseplants.

Pineapple flower

Homegrown Pineapples

The pineapple (Ananas comosus) is one of the best tropical fruits to try growing at home and with a bit of care it will even produce fruit.

I speak from experience, because many years ago when I was still living in Cardiff, I made the HTV News at Christmas with my homegrown pineapple. I was filmed watering my pineapple plant and talking about how I had cultivated it. I said I used soil from the back garden and water from the tap, and that I repotted it when the plant got too big for the pot it was in, but that was all I did. An expert from the Welsh National Botanical Centre praised my achievement, and I was proclaimed as the first Welsh pineapple grower.



All you need to do to follow my example, is to twist the spiky rosette part off from the top of a pineapple, and then remove the leaves at the base to leave a stump. Leave this to dry for a few days before planting by pushing gently into a pot of damp compost. If you are in luck, there may already be tiny roots sprouting from this stump before you plant it.

Once well-rooted the pineapple will grow into a large rosette of spiky leaves and after a few years, all going well, it will produce a flowering stalk right in the centre. Mine took five years to flower but that was in a house with no central heating in Wales! The tiny flowers are a pretty lavender shade and surrounded by reddish spiky bracts.

After the pineapple has ripened and been removed side shoots will form on the main stem. These can be removed for further pineapple propagation or if left on the original plant long enough, they can flower and produce a second crop. I managed to grow another pineapple like this.



Taro or Inhame

The taro (Colocasia esculenta)  is a root vegetable that is sold as “inhame” in Portugal, and ñame” in Spain and the Canary Islands. The corms are cooked by baking, roasting or boiling, but what many people do not realise is that if planted these corms will produce a most attractive houseplant if given the chance. In fact, the taro is often grown as an ornamental plant known as “elephant’s ears.” It gets this name because it has large heart-shaped leaves.

Elephant's Ears

The taro likes a very damp compost and will grow submerged. You can often see these plants growing in fountains and water gardens. I have grown taro in a pot of compost I stood in a bucket of water.

Kiwifruit

You can grow kiwifruit (Actinidia deliciosa) vines from seeds from kiwis you have bought. It takes a long time for the plants to grow big enough to produce flowers and fruit but it can be done. I managed this when I was living in Wales still and followed up my pineapple story in the local media with my success at harvesting kiwifruit in my back garden. I admit it took five years before I had any fruit on my vines but I felt a real sense of achievement when I had my first crop of seven kiwifruit and my picture in the South Wales Echo. If I can grow kiwis in Cardiff, think how much better they would do here in Iberia!

Avocado

Avocado Tree

The avocado (Persea americana) is another fruit that can be easily grown. Just plant the large pits in a pot of compost and wait for them to sprout. Many people think you need special techniques for getting them to germinate but I have never found this to be the case. Simply burying a pit in a pot of damp soil has worked for me.  Your homegrown avocado will make an interesting houseplant when it is young and can be moved outside in Iberia when it gets bigger. Eventually it will form a large tree.

Ginger

Ginger

Another easy plant to grow is ginger (Zingiber officinale). This root vegetable is commonly used as a spice for curries and other hot dishes, and in herbal teas. Fresh ginger roots or rhizomes are easy to find in supermarkets. They will often start sprouting green shoots when in storage, almost as if they are inviting you to plant them!

All you need to do is to break off sections and plant them in a pot of compost. The shoots will take a few weeks to really sprout but will then keep growing into a plant with long narrow leaves. You can harvest your first crop of ginger later the same year, and fresh ginger you have grown yourself is so much fresher than the ginger you can buy.

There are many more fruits and vegetables that will grow from seeds, pips or roots of shop-bought produce.  Why not see what you can get to sprout? It can be a lot of fun finding out what can be grown and what the plants actually look like!

The Cacti of Iberia

Cacti of Spain and Portugal 

Prickly Pears (Opuntia dillenii)

You will see cacti growing in many parts of Iberia, mainly types of prickly pear cactus, and in some places, such as the Canary Islands, they are so common that it is easy to assume they are part of the native species. They look just right for the semi-desert landscapes. But in fact, there are no endemic cacti in Spain or Portugal, though some species from the Opuntia and Cylindropuntia genera have become widely naturalised. There are actually as many as 20 different types of Opuntia recorded as growing wild in Europe and the Mediterranean, but we are looking at the ones found in Iberia, and the ones you are most likely to see.

Prickly Pears

Harvested Prickly Pears

Cacti in the Opuntia genus are commonly and collectively known as prickly pears. The name refers to their edible fruit, which are found budding from the large and very prickly pads. These cacti have large numbers of tiny spines or glochids that project and will detach easily from the small bumps on the cactus skin that hold them, and which are technically known as aeroles.



There are two main species of prickly pear seen in Iberia: O. ficus-indica and O. dillenii. The first of these is known in English as the Indian fig Opuntia and the Barbary fig. The plant is referred to as “nopal” in Mexican Spanish, and its fruit is a “tuna.” The flowers are red, yellow or white, and the fruits are green, turning yellow or reddish as they ripen. It has been historically grown as a food crop for thousands of years in Mexico. You need to carefully remove the spines on the tunas by rubbing in an abrasive material and also peeling the fruit. They are usually eaten chilled and resemble watermelon in flavour. The fruit are also used to make jams and jellies, and have been used in the production of alcoholic drinks too. You will often see them for sale on fruit and vegetable counters.

The green pads, or nopales, can be eaten too. Again, you must carefully remove the spines, and the sliced pads can be fried or boiled.
Prickly Pear Flowers

The species O. dillenii is also known as O. stricta, and in English it is called the erect prickly pear. It has lemon-yellow flowers followed by purplish-red fruit with smooth skins, though, once again they are protected by spines. I used to eat a lot of these fresh when I lived in Tenerife, and used to manage to safely peel them using my thumb and finger-nails, but it is a tricky procedure so cannot be recommended. The tiny spines are notoriously difficult to get out of you and they hurt! This cactus is actually regarded as an invasive weed in many parts of the world where it has invaded the land. All species of prickly pear spread easily from pads which have broken off from the parent plant but which then root where they have fallen.

Cholla cacti

A very prickly Cholla

Speaking of cacti that spread easily from pieces that have become detached brings me to the cholla cacti in the Cylindropuntia genus. In Spain and Portugal there are two species that are commonly encountered: C. spinosior and C. imbricata. The first of these is known as the walkingstick cactus or the spiny cholla, and the latter species is called cane cholla or chain-link cactus. Both species are well-protected with large numbers of the most vicious spines imaginable all over the sections of the plants. The spines will easily break off, and the sections of cactus can also be readily detached. My advice is be very careful with these plants, because the spines are really painful. Fall accidentally into one of these and you will regret it!

The cholla cacti come from Mexico and the southern states of America but have spread to many parts of the world, where like the prickly pears, they have become invasive weeds.  Although these cacti can be problem plants, they also make formidable fences. Anyone caring to ignore them is asking for trouble!



Peruvian Apples


In addition to the cacti in the Opuntia and Cylindropuntia genera, you may see the Peruvian apple cactus (Cereus repandus/peruvianus) growing in gardens, and also on waste ground in Iberia. This cactus is very tall and produces columns that can easily reach as much as 10 metres in height. It comes from South America but stands up to cold periods in Spain and Portugal well. This cactus produces spectacular cream-coloured flowers that open at night and are only open for the one night. The flowers turn into edible fruit, known as Peruvian apples or pitaya.

Besides all these cacti that might be encountered in Iberia, many gardeners introduce other species into community-used ground near their homes, and cacti often root when they have been thrown out, so you can at times find all sorts of surprises but none are native plants. Gardeners in Portugal and Spain often grow many cacti outside that in the UK are strictly houseplants. The hot summers and mild winters give us an advantage when it comes to cactus growing.

The Ancient Herbalists Assigned Herbs to Planetary Rulers

Why the Ancient Herbalists Assigned Herbs to Astrological Rulers

Nicholas Culpeper (Photo: Public Domain)

As far as we know, there are no more planets in this Solar System that have plants growing on them, though some people have suggested there may be vegetation of some sort on Mars. Ancient herbalists, however, had a system of assigning herbs to planetary rulers; in other words, they claimed that deities linked with the heavenly bodies held dominion over herbs that grow on Earth. Let us take a look at a selection of herbs that were placed under the astrological ruling of other planets, and see why it might have been that herbalists, like Culpeper, decided to assign them to specific heavenly rulers.

Herbs of Mars


Dragon Tree (Photo: Public Domain)


Nicholas Culpeper was one of the most famous herbalists who believed that medicinal and culinary plants could be grouped in this way, according to their various characteristics that were linked to those of a specific god or goddess. For example, because Mars was regarded as the god of war, herbs that had something aggressive about their physical appearance or something that resembled blood, were candidates for being ruled by this planet. The strange Dragon Tree (Dracaena draco) is a perfect example of a herb ruled by Mars because it has sword-shaped leaves, reddish-coloured berries and it bleeds a resinous sap that goes a dark red when dry and is known as dragon’s blood. The Dragon Tree comes from the Canary Islands, and a specimen in the town of Icod de los Vinos is thought to be 1,000-years-old or more. It is known as the "Drago Milenario," has its own park, and is a tourist attraction nowadays.

Steve Andrews explains why the Dragon Tree is a herb of Mars

Herbs of the Sun

Herbs of the Sun include the Sunflower (Helianthus annuus) and the Chamomile (Anthemis nobilis). These two plants have petals that radiate out from a central disk like the rays of the Sun, and the Sunflower is, of course, a bright yellow, which is a colour linked with the central star of our Solar System. The St John’s Wort (Hypericum perforatum) is another herb in this group. It has yellow star-shaped flowers and is harvested in midsummer when the Sun is at its strongest and the days are at their longest. St John’s Wort has become well-known as a herbal antidepressant, and one of its alternative names is Sunshine Herb. Mistletoe (Viscum album) is an herb of the Sun because it was traditionally harvested by Druids at the time of the Winter Solstice. It was cut down from an oak tree using a golden sickle.

Herbs of the Moon

Herbs ruled by the Moon were often ones that are associated with water, because the Moon is linked with the oceans because it causes the tides. White flowers or a silvery colour on the foliage are other characteristics linked with the Moon, and plants that have something to do with the night might also be thought of as herbs of the Moon. The White Water Lily (Nymphaea alba) is a herb ruled by the Moon. This is because of its white flowers, rounded leaves, like full Moons, and because it grows in lakes and ponds. The Jasmine (Jasminum officinale) has white blooms and its perfume is strongest at night. The White Willow (Salix alba) is another herb under the dominion of the Moon. Willows, of course, like to grow by water. The Lettuce species (Lactuca spp.) are ruled by the Moon too. This is because they have a white milky sap if cut. This sap is known as "Lettuce opium" and has similar sedative effects.

Herbs of Mercury

Mercury was thought of as the messenger of the gods, so herbs ruled by this planet have to really communicate to us in some way. Strongly aromatic herbs were often chosen as herbs of Mercury. The Fennel (Foeniculum vulgare) is a great example of a herb in this group. It communicates to our senses with the visual appeal of its tall graceful stems and ferny foliage, to our tastes with its sweet and spicy flavour like aniseed, and with its scent like anise when crushed. It is used both as a culinary herb and in herbal medicine.

Periwinkle (Photo: Public Domain)

Herbs of Venus

Herbs ruled by Venus, not surprisingly include the Rose, which is a symbol of love and passion, and, of course, Venus is the Goddess of Love. The pretty blue-flowered Periwinkle (Vinca spp.) is another herb in this group, and this is because it has been used in love potions and spells. It was thought that merely sprinkling this herb under the bed of a couple of lovers would increase their passion. In fact, the Periwinkle is a poisonous plant but that never stopped it being linked with love.

Lime Tree (Photo: Public Domain)

Herbs of Jupiter

Jupiter is a giant planet and expansion is one of the characteristics associated with it as a planetary ruler. Various trees come under its dominion because of their spreading branches. One of them is the Lime Tree (Tilia spp.), a tree which gives us lime flower tea, which is known to help relaxation and is very popular in many parts of Europe. It was once thought that anyone suffering from epilepsy would be healed by merely sitting under a Lime's branches. The Oak (Quercus) is a very important and sacred tree for Druids, and it too comes under the rulership of Jupiter.

Deadly Nightshade (Photo: Public Domain)

Herbs of Saturn

Saturn is another gigantic planet and famous for its rings. To the Ancient Herbalists it was associated with the passing of time and with old age and death. It symbolises the “Grim Reaper.” Many poisonous herbs come under its dominion. The Deadly Nightshade (Atropa belladonna), the Henbane (Hyoscyamus niger), Hemlock (Conium maculatum) and Monkshood (Aconitum napellus) are all very dangerous herbs that were once used by witches as ingredients for their “flying ointments.” The Morning Glory (Ipomoea violacea) is another herb under the dominion of Saturn. Its flower has a circular mouth to a funnel-shape and could remind us of the Rings of Saturn. Its seeds, especially in varieties like "Heavenly Blue," contain lysergic acid amide, which as hallucinogenic effects and has often been used by hippies and shamans because of this. This flower looks so beautiful it could be from another world, and its psychoactive effects could make you feel like you were on one.

In Conclusion

Thinking about how the herbalists assigned various herbs to the rulership of planetary deities, according to their characteristics, certainly makes for a fascinating study and something for us to think about. My new book Herbs of the Sun, Moon and Planets (Moon Books) explores this subject in greater detail.

Great Crested Newts in Heath Park Pond and the Flora and Fauna of Heath Park

Heath Park is a wonderful nature conservation area

Heath Park Second Pond (Photo: Steve Andrews)

Heath Park in Cardiff is a wonderful area for nature conservation and is home to a colony of the rare great crested newt (Triturus cristatus). The amphibians breed in the pond there that has been in the park for very many years.

Great Crested Newts

Those responsible for the park and pond’s upkeep have very wisely left dead tree-trunks around the edges of the pool and in the woodland that surrounds it.

Habitat created for Great Crested Newts (Photo: Steve Andrews)

Water plants, such as watercress (Nasturtium officinale) are enclosed in mesh so that they are protected and this creates a wonderful area for the newts to lay their eggs in and to hide. Great crested newt females wrap their eggs in the leaves of aquatic vegetation, as do other species of newt.

Aquatic plants (Photo: Steve Andrews)

An information board gives a lot of information about the great crested newt, including how far it travels away from water. The much smaller palmate newt (Lissotriton helveticus) also breeds in Heath Park Pond. This comes as no surprise to me because I used to have a girlfriend many years ago, who lived in the nearby King George V Drive that circles Heath Park, and these far commoner newts could be found in the garden pool of the house where she lived. On the info board, there are illustrations and notes about the other interesting species of wildlife that can be seen in the pond. The common frog (Rana temporia) is another amphibian that breeds here.

Info board (Photo: Steve Andrews)

Aquatic insects that use the Heath park Pond include the great diving beetle (Dytiscus marginalis), the water boatman (Notonecta glauca) and dragonfly and damselfly species. The great diving beetle and its larva hunt tadpoles, small newts, fish and worms. The larvae have large mandibles with which they grab their prey as they suck out the life-blood. Both adults and larvae will bite. The adult beetles fly by night to look for suitable stretches of freshwater. The water boatman or backswimmer can also fly. It is a predatory bug that feeds on mosquito larvae and other small water creatures. It gets its name from its habit of swimming upside down and using its legs as paddles to propel it through the water.

Alien and invasive species

Parrot's Feather

The information board includes a warning and request: the public are asked not to release species that are non-native and alien to this country. An example being species of terrapin that can be a danger to British wildlife. The species of water milfoil known as parrot’s feather (Myriophyllum aquaticum) is mentioned as an example of an invasive species, and it is pointed out that this particular plant caused a problem at Heath Park Pond where it grew abundantly and had to be carefully removed. It is a threat to British species because it grows so well that it displaces native plants.

Elsewhere in Heath Park

Elsewhere in Heath Park they have constructed a second pond near the golfing area. The information board explains that great crested newts do best in places where there are more than one pond, so that if one pond dries up in hot weather, for example, the amphibians can still breed in another. I don’t know if any newts are using it but it is certainly big enough and there were two mallard drakes swimming around on it.

Walking a dog to Heath Park Main Pond

There is quite a lot of woodland and areas which were once rough ground and scrub have been allowed to grow into thickets of small trees and bushes. There are plenty of great places for birds and other wildlife to live in the park. It is reported that the green woodpecker (Picus viridis) lives in this woodland, and I wouldn't be at all surprised because it is a great place for them.

Paths help you enjoy walking around the woodland and many people take their dogs for walks in Heath Park.

In the grassland and extensive lawns of Heath Park there are extensive colonies of lady’s smock or cuckooflower (Cardamine pratensis), which takes its name from its habit of flowering around the time when the first cuckoos could be expected to arrive in the UK.

Cuckoo Flowers (Photo: Steve Andrews)

It is of especial interest, and a useful plant when it comes to wildlife conservation, because it is one of the main food plants of the caterpillar of the orange tip butterfly (Anthocharis cardamines). This pretty species, with orange tips on the forewings of the males, has been increasing again in numbers in some parts of Britain, so anywhere that plants that its larvae feed on grow, is going to be helpful in ensuring this butterfly’s survival. The cuckoo flower used to be gathered as a substitute for watercress, and like the latter plant it likes to grow near water.

The abundance of lady’s smock plants in the park, as well as the natural woodland, and the obvious great attention that had been paid to making the ponds a suitable habitat for great crested newts and other aquatic wildlife, made me feel that Heath Park is one of the best parks in Cardiff for nature conservation.
