Developing and improving propagation methods for terrestrial orchids

Critical to any orchid reintroduction project is being able to grow the orchid in cultivation. With our partner organisations the Royal Botanic Gardens Victoria undertake hand pollinations of remaining wild populations for seed, then culture the specific mycorrizal fungi required for each species and germinate our orchids symbiotically in our laboratory. Many of the endangered orchid species that we work on have never been grown in cultivation before and success relies on learning from both successes and failures to improve the methods that we use.
