what are the different medium in planting cut flowers?

Answer 1

Some of the various media used to support cut flowers (not plant them) to keep them supplied with water are
Florists' foam (the green stuff that holds water)
Metal frogs (spikes on a backing or a medium screen either of which keeps the stems in place)
Marbles, stones, or glass shapes (acting like soil to hold stems)
Plastic gel that swells with water.
