A good rule of thumb to remember when looking at flower stuff and there is more than one type of thing that could be seed, is to test with your fingers. The seeds will hold together while the other stuff will crumble or if moist roll up in a ball. Viable seeds are always hard and will not easily crush/break under pressure.
