One trip in New
Caledonia is enough to make you love this amazing island.... Plant diversity is
remarkable and the range so very different from other regions. One is rendered speechless at every turn. I had a great
opportunity to explore this country guided by a young student who has become a
great researcher botanist: Jean-Christophe Pintaud. Unfortunately,
this
astonishing vegetation is quite difficult to acclimatise in Corsica.
New-Caledonian soils are mainly composed of two substrates: the shale
and
ultramafic rocks particularly rich in nickel and chromium but poor in
nutrients
essential to the growth of plants, such as nitrogen, phosphorus,
carbon, or even
potassium. Here, there is nothing of that at all but decomposed
granite
rocks.... Another problem
remains the acquisition of plants. The Araucaria
collection comes from seeds collected by Professor Dr. Morat, former Director
of the National Museum of Natural History. In my garden Arecaceae failed to flourish on account of the conditions (too
much summer heat and some lack of water, rodents, etc.). Only Kentiopsis
oliviformis, Cyphophoenix elegans and, of course, the Chambeyronia macrocarpa have coped successfully. The Pacific
Islands have such beautiful and interesting vegetation that it ought to be represented
in the garden so is more natural than to associate it with that of New-Caledonia! The niaouli (Melaleuca quinquenerva) originating in New-Caledonia, but naturalized in many of the Pacific Islands, is a proper link between all these locations. |
