first of all... I'm sorry Sharon, but you are well and truly addicted
but hey, don't feel bad... join the rest of the wonderful folks on here whoa re as crazy and smitted about orchids as you... (except for me, I'm just crazy!)
So, this Wildcat of yours... because it is a replica (or to use the proper horticultural term) a mericlone of an original plant ie 'Bobcat', then the variation in size of flower will only be through maturity and health of the plant and good growing environment.
That, I guess, is why at Orchid Shows, you will see many of the same plants but one will come first etc etc... it all comes down to us as well... if we do right by our orchids, then they will reward us with a nice flowering.
