Abstract:
The hardy and half hardy orchids i.e. temperate terrestrial orchids, are a very large and diverse plant group. Despite their "exotic" flowers, interesting biology, the large number of species and their great popularity as wildflowers, the temperate orchids have never featured, to any great extent, either as garden plants or as potplants. The main problem in the large scale production of the temperate terrestrial orchids is propagation. To elucidate some of these problems and thus make the introduction of hardy or half hardy orchids as potted plants possible, a three and a half years research project was launched. Three years after the start of the project, some of the goals have been achieved, but only for a few orchid genera and for a few species. The highest degree of success has been reached with species of Dactylorhiza, Disa and Cypripedium using aseptic in vitro propagation.
