It is a nice photo. Not positive it's a hyacinth, but it isn't an agapanthus. You're looking only at the individual flowers and not noticing how the entire inflorescence is constructed. There is only one little flower on the end of whatever each little stalk is called, many of which make up the whole umbel-like inflorescence, not multiple blooms per stalk as your picture shows. My botanical vocabulary is lacking, but my eyes know what they see
