Oh dear, I just started some cuttings from new growth. Should I discard
them and start over or is there a chance they will root anyway?

No
You need stems that have flowered

if i throw the bottle over
the plantings and love them and stuff?

No
You'll probably cook them. Try using open-topped gallon-sized plastic
milk jugs.

i envision a row of glinting and humid glittering hemispheres of 2l
bottles nurturing my rude cuttings jammed into a nice little garden
bed...

Why not just put the bottles out, if you'd like.
