so sorry thst this happened to what could have been beautiful blooms. If it is of any consolation to you things like this happens to all of us at some time. Right now I have a Catt. that the yellow breast attacked the sepals before the bud even burst, and spoiled the flowers. There is another sheath, with buds, coming and I am hoping the birds will let me have those.
Don't despair your next blooming will be magnificent.
