Duchy College Micropropagation Unit
A nationally renowned research unit for the propagation and cultivation of endangered plant species
The micropropagation unit at Duchy College, Rosewarne was established in 1991, primarily as an educational resource for horticultural students studying at the College. Over a number of years, the Duchy College facility has become an important, nationally renowned, research unit for the propagation and cultivation of endangered plant species.

The Rosewarne Micropropagation techniques support the following;
- The development of new propagation protocols for new retail lines
- Conducting research on plant health
- Preservation and reintroduction of important species
- Rare Species Conservation
- Bulking up nursery collections
- Propagating new varieties, in confidence, for commercial release
- Producing virus free stock by meristem culture eg. Potato, Daffodil, Rhubarb
- Propagation of difficult to root species, eg. Daphne
The Rosewarne Micropropagation facility is still a valuable educational resource and we endeavour to keep the facility to a high standard of quality and cleanliness to encouraging best practice in our students. It is run by a small, dedicated and knowledgeable team.
