If you cut flowers from your garden to bring inside, do flower arrangements for a church or events, or buy flowers from a market, this flower food is supposed to extend their life. Collected from buying supermarket flowers and not needing multiple sachets in one vase. Didn’t want to stick them in landfill. There are probably a hundred sachets in the tin, including both powder and liquid food. Tin itself is rusty, but I imagine the unopened sachets last forever!
For collection from Riber, near Matlock.
