It affects everything. The flavors of (say) avocado-flower honey and citrus-flower honey are so different, that you might not recognize avocado honey as honey if you're not used to it.
Wow, I've never heard of avocado-flower honey. What kind of flavor does it have?
More complex, a little less sweet. I don't know how to describe it, except (to paraphrase Douglas Adams), "it is quite, but not entirely, unlike citrus-flower honey."
