The Orchid Society of Great Britain

Judging classes

Only members of the OSGB are eligible to compete in monthly Table Shows, but the Spring and Autumn Shows are open to non-members.

At these latter shows rosettes will be awarded for first, second and third places in each class.
OSGB trophies will be awarded to members of the OSGB only. If the winner is not an OSGB member, a certificate will be awarded in place
of a trophy. Any plant entered in classes 1 to 39 must have been in the entrant’s possession for at least 12 months.

​

At the discretion of the judges, any class with numerous entries can be split and a new sub-class created if needed.
The Society reserves the right to amend the schedule as necessary according to any official reclassification of the genera etc.
