Having grown these plants for about 50 years in South Africa I can not agree at all with this information as regards seed production.

Practically every flower will produce viable seed pods if hand pollinated regardless if they are self or cross pollinated.

The seed can be grown in vitro with ease but here in Durban I simply plant the seed in prepared seed beds with a good degree of success.

This orchid is a pioneer plant in its natural habitat which matures to flowering size in between one and three years depending on conditions.

Over the last few years I have trialed these plants as green roof plants under conditions where they only receive natural rainfall mostly in the summer months with great success

For anyone wanting more information on Eulophia speciosa or wanting information on growing it on green roofs take a look here http://www.ecoman.co.za/green/green_docs/eulophia_speciosa.h...
