Grandmother

[critical mass]

Heslopian

Lots of good images here.

Promenade works in the rhyme, unless its used in square dancing
then it's (aide).

I think strum in stead of play, or something similar would work better.
would sound more musical.
Play is generic I think.

I agree with everyone else about the purple flower line.

Not much to dislike in this.

Thanks
