Sorry to disagree but I think the answer is flower-tops. The poem is about nature yes but the term heads seems to refer to the flower-tops as the topic was daffodils. This is personification as if the daffodils were humans that could dance.
Okay. I hope I'm right with this
1.) Princes is showing ownership so it's princes' rescues is rescue's and dragons is dragon's
2.) Chocolates would be Chocolate's, and again, ownership, mothers is mothers'
3.) You don't put an apostrophe in takes because you don't put apostrophes in verbs. There is no apostrophe in minutes because it's telling how many minutes it takes to get somewhere. Of course in a sentence like, "Let's have a minute's talk," you would place an apostrophe but not in this case. (Not sure about this answer) And suns you would put an apostrophe after the s because it is again showing ownership.
4.) Don't put an apostrophe in lilacs or curtains because grammar rules are weird. But you do put an apostrophe after the s in rooms because it's the rooms charm. The room owns that charm and it's talking about just one room.
Hope this helps. I don't know if everything I've said is right but I've done my best.
