extract its scent before its 'one night stand' comes to a close? I've also heard the petals are edible after they are through blooming. True? I've only got one night left... tonight five blooms! last night there were four! Just wish there was a way to preserve one or the scent but they seem too fragile and way too juicy for pressing.
Thank you!
p.s.sorry looks like a couple photos went through sideways...I don't know why but this was my second re-do.Thanks for the patience this is my first post here and hope I've got the right forum as well... yikes.
