How many flowers are typically in a bouquet?

[Harper]

I am trying to budget for some table decorations and I’m looking for a standard estimate. When you buy a medium-sized arrangement at a local florist or grocery store, how many flowers are in a bouquet on average? I want to make sure the vases look full enough for a professional look, but I’m not sure if the count usually includes the filler greenery or if it refers strictly to the focal blooms.
