Maybe I should have left out the flowers

Our CSA delivery this week included remarkably few actual vegetables, but a whole sh*tload of basil. So I figured it was time to try that pesto recipe. It came out ... interesting. I haven't decided whether I like it or not. Was I supposed to use only the leaves? I included the flowers. Was that a mistake? The resulting pesto has a very distinctive flavor - not unpleasant but very different from store-bought pesto.
