What flower is this?
Thanks for submitting your question to Ask an Expert. Unfortunately, the images are not clear enough nor from the right angles to make an identification. Flowers in floral displays can be composed of numerous greenhouse/tropical species that are not grown locally (i.e. they are grown either in the southern regions of the US or further south in Mexico or South America). A local florist may have a better idea of what the flower is because they may have worked with it. Where was the arrangement purchased? They may be familiar with it as well.
Sorry I could not be of more help.
