Dear Susan, how lovely to hear from you! I if asked don't really have a favourite, but I adore terrestrial Lady's slipper orchids.
This year at Chelsea there were untold new varieties and many very rare ones from all over the world, so that was a great treat to see.
This is the Kentucky Lady's slipper orchid but pink, and is stunning, It is [
Cypripedium kentuckiense pink. Unfortunately it did not say if this was a variety or a naturally occurring one,
This is
Cypripedium U.R.G. 'Puebelo' and is a hardy hybrid.
This was undoubtedly the star of the show to me as the highly rare
Cypripedium calceolus is a rare orchid in the UK although it does grow here naturally.
This is a hybrid and is
Cypripedium calceolus Var. pubescens. it was developed in America.
