Twenty years ago, I did that for my daughter-in-law’s shower, froze violets in ice cubes, served with pink lemonade—it was gorgeous! We used lilac blossoms on the tables, too, it was a lavendar themed shower.
I love eating flowers. And no, I don’t spray, I have a stocked 1/2 acre pond and I’m afraid anything I might spray in the garden will leach into the pond sooner or later, and harm the fish. It could also harm the hummingbirds, who are everywhere.
I hosted a Garden Party like that for my 40th Birthday. My girlfriends are already looking forward to my 50th. Gardening is good, clean fun. :)
