Pretty sure the 'Seven Flowers' thing was referenced in an older Tani Takeshi Touhou 4koma, so I'm being lazy by not explaining it here.

Is that your way of asking Osa-Sanae to die, Osa-Reimu? You might get a serving of Sanaelation. Also, with that plucked sunflower, incoming Yuuka.

I doubt that part. Considering she(?)'s essentially Yuuka's pet/companion/pillow, it's likely Osa-Reimu gets a free pass on her flowers.
