Thanks for your reply! All attendees are old enough to not worried about having to have clean versions of tracks, no kids present. No ‘first dance’ with the bride, but we will be dancing together with people. There will be an explicit break from one playlist to the other, about 3 hours after the ceremony.
So pg playlist is 3+ hours long, party playlist is about 2 hours to be safe.
Its in a back yard setting, pretty casual feels.
If your bed is absolutely isolated and there is no way for the runner roots to escape, mint would be a good option. Really make sure it’s isolated though, dig down to the bottom and make sure it doesn’t connect to your other dirt areas like lawn or other planters. If there is a way for it to escape it will, and it will take over.
