A few years ago, Theo Wilms decided to try an experiment. He wondered if it was possible to grow orchids out of tree ferns. Such an orchid orchard doesn't exist anywhere in the world, but for an agricultural scientist, that is just a challenge.
It all started in the early 1980s when Mr Wilms was working for what was then called the Taranaki United Council.
"They asked me to look into all the agricultural and horticultural systems in the province to see if any of them could be expanded." As far as outdoor horticulture was concerned, the answer was no, mostly because of the wet climate.URL : http://www.stuff.co.nz/stuff
