Subtropical Climate

Canarius | Tuesday May 11th, 2010 |

Subtropical climates are non tropical climates with cool winters with little or no frosts. In subtropical climates, Winter is a noticeably cooler season. It is relatively warm, but never as hot as the summer season. These climates rarely, if ever, see frost or snow. Subtropical belts exist in both hemispheres and they are located just North and South of the tropics.

Rainfall patterns vary widely throughout the subtropics including hot deserts, savannas, monsoon forests, humid forests and the warmer parts of the Mediterranean climate zone. Subtropical regions include:

Northern Hemisphere: California, Texas, Florida, Canary Islands and Madeira, parts of the Mediterranean, northern India, southeast China, Southern Japan

Southern Hemisphere:  So. Brazil, N. Argentina, Parts of Chile, Uruguay, large parts of Australia and coastal South Africa (Mostly Natal)

Subtropical Climate in Europe

Europe has some Subtropical spots too in warmer, coastal areas within the mediterranean climate area. The climate in the Southern Mediterranean, with little or no frost , can be defined as Subtropical climate. This is the case of the coastal areas of Southern Portugal (Algarve), Southern Spain (Andalucia, Almeria, Murcia), Southern Italy (Sicilia, Calabria) and Southern Greece. Even cooler Subtropical areas can be found in Southern France (Cote d’Azur). Warmer spots are also found in the United Kingdom, precisely in the Isles of Scilly with 6 °C (42.8 °F) average in the coldest month. Of course there is a lot of difference between the Isles of Scilly and a typically hot subtropical climate like Florida. The English islands have a cooler, even climate reminiscent of the mountain climate in the warmer Subtropics.

The Canary Islands are located in the Subtropical belt too, very close to the tropics. The climate is frost-free on the coast, but it less hot than in many Subtropical areas because of the trade winds and the cold ocean. The Canaries are the only territory of Europe located straight into the subtropical belt.  Even here we do not have a typical subtropical climate, because our climate is also Mediterranean, because of the rainfall pattern and also Oceanic, because of the cooling effect of the sea.

Exotic Gardens and Crops in Subtropical Climates

Many tropical species will tolerate the winter in the Subtropics and will grow outdoors. More than 500 palm species can live in Subtropical areas with little or no frost, exotic flowers such as Bird of Paradise (Strelitzia) or (Heliconia) and many Cycad species. The beautiful Bromeliad Family is a must in any garden. Hundreds of species of Succulent Plants from dry areas can grow and bloom as long as they are kept dry in winter. The dry subtropics include many of the world desert, so here is where most desert gardens are developed. Also the tropical succulent species will do fine, like Melocactus or Adenium and Pachypodium if kept well drained. Palm-like desert plants, such as Yucca and Dasylirion, thrive to perfection.

Fully tropical species can grow in the Subtropics. They may slow down or stop in winter but most will grow reasonably well. Many tropical fruit trees grow freely. Mango, Papaya, Sugar Cane and Avocados are produced commercially in various subtropical regions of the world. Occasional frosts or short summers limit the spread of tropical horticulture in the Subtropics.

An impressive number of Palms and Cycads is kept by collectors. Many tropical flowers will winter outdoors. Bromeliads can be used freely as garden plants, as well as Heliconias. In lower latitudes, Cacti and Succulents are simply part of the landscape. Different species of Agave, mostly from Mexico, grow wild on the hillsides of Mediterranean Europe and Aloes flourish in pots and gardens. Large specimens will often enhance the garden of the villa, in the ground or in large pots. Southern Spain and Portugal are even sunnier, almost as Northern Africa so Cuban Royal Palms (Roystonea regia) and Royal Poincianas (Delonix regia) thrive in many coastal location, papayas will fruit with little effort.

With some protection and some effort you can grow subtropical plants in colder climates. Visit our blog section about Tropical Gardening in Northern Climates.

The video clip of the Frost-Hardy Palm Trachycarpus princeps in Habitat

Canarius | Thursday May 6th, 2010 |

These are marvelous images from a place in China called “The Stone Gate”, in the habitat of the cold resistant Trachycarpus princeps – a palm species with silvery fan leaves. This video was published in 2008 by Stéphane Ringot, with the original name of “Voyage au Pays des Trachycarpus Princeps“: Trip to the land of T. princeps.

The video shows:

  • The trip by boat and the walk through the forest.
  • Adult, tall palms growing on the vertical cliffs, in full sun, with no soil.
  • Seedlings, juveniles in the shade of the forest
  • Beautiful vistas from the cliff.

Trachycarpus princeps is a new species of palm which is hardy to frost and cold conditions in Europe.

Canarius.com is now offering seedlings with palmate leaves in the shop: Trachycarpus princeps

Mango Varieties sold by Canarius for Mediterranean and Subtropical Climates

Canarius | Wednesday May 5th, 2010 |

The mango tree, Mangifera indica, is an evergreen tropical tree tolerant of cooler conditions and short droughts. There are literally thousands of different types, called varieties or cultivars.

Canarius offers a selection of varieties better adapted to non tropical climates, grafted on a the hardy rootstock “Gomera-1″. You can buy young trees in the shop. Mango will effortlessly grow and fruit outdoors in warm Mediterranean Climates, such as coastal areas of Portugal, Spain, Italy and Greece. Adult plants resist short freezes at -4°C (25°F), but young trees are more sensitive. Mango is the third most important tropical crop in the Canary Islands, after banana and avocado.

Different varieties hide different flavours, fruit sizes and colours. Mangos may be dark green, greenish-yellow, yellow, red, orange or purple. By planting different varieties, the fruiting season can be extended up to four months. Low-growing varieties, such as ” Keitt ” can grow and fruit in large pots. The yellow Canarian mango “Gomera” is the most resistant to cold and frost and it fruits even in South France. “Lippens” fruits well in cooler conditions, so it is planted at higher elevations in the Canaries. “Osteen” is grown commercially in Mediterranean Southern Spain.

Grafting is the best way to reproduce the best varieties. The mangos sold at Canarius are all grafted and the rootstock is the hardy canarian mango “Gomera-1″, because it is resistant to drought and wet, cool soil in winter. Our mango trees are hardier to cold because we use this type of rootstock.

Fruits of Mango Gomera-3. Gomera is a hardy Canarian variety used as a rootstock. Mango trees grafted with gomera are less sensitive to cold and drought.

Canarius offers the varieties that are planted here in the Canary Islands, in our subtropical-mediterranean climate. We ship to your home the same grafted trees that are sold to local farmers , ready to go to the field: same plants, same size, same deep pots.

The plants you purchase are at least 2 years old, because the root trees are grown for 1,5 years before grafting. Then they are grafted and grown for at least six  moremonths. These plants will fruit in two or three years. They will bloom very soon but you will need to remove the inflorescence during the first two years, to allow stronger vegetative growth before fruiting.

Grafting Mangos in the Nursery

In our shop you can purchase a wide selection of mango trees of different varieties. All trees are grafted by hand, with specific cultivars. We ship to any countries in Europe.
