Well done! I can't even pick a favorite stanza.
Love the line -- "sweet enough to attract ants", which is so true about a draft (and peonies!)and the last stanza..."lopsided, fragrant""cut for a vase or for a grave"...not sure why... but there's something about the messiness of the bouquet and that fits so nicely with how long the bouquet lasts that interests me! Maybe, too, it's because as a Midwesterner, I grew up with peonies and think of them as plants of my mother and grandmother, and know that lives (and flowers) can be messy and temporary.
