Hi Ford! what part of the south are you in? im just south of London. anyway back to your topic.... have you tried equatorial plants (if they still exist?) i had an old list and i can remember seeing it on there, however they are seedlings, but normally they have a stand at the London Orchid show selling larger plants of their stock. Or rareplants.co.uk i know they have alot of hardy orchids including a good variety of Cypripedium species and hybrids, but not sure if they have Ophrys.

hope this is of some help!
