Do you mean Cattleya orchids? In post 33 none of the flowers look big enough to be Catts.
maybe not... maybe phaleonopsis?? or maybe its just peonies..n roses..i would like to see a bigger photo. I am surprised(I don’t know why I am) that it was so pretty incl. Chelsea. course, Jenna Bush’s was beautiful too. But Chelsea’s dress is one of the most beautiful I’ve ever seen.I do wedding flowers almost every weekend :)
