That's really nice! I like the progressive expansion: hovering with the mouse brings up a name, clicking brings up a dialog box, and then following the link to the Plant Database gives you everything.
P.S. I like to "CTRL-click" instead of "click", so that I get a new tab and can always get back to the image set with one click (don't have to use "back - back").
Would it be worthwhile to add "See the Parent Plant entry for this plant" as an option at the bottom of database pages?
