It is a brand name of a gravel like 'expanded shale' that is sold as a permanent soil amendment to increase aeration as well as to be used when planting to literally surround the bulb with a layer of rocks that repel voles (scratches their tummies or something like that)... so far it has seemed to work...bulbs are coming up through it no problem....I will reserve judgement as to how good it really is until they make it to next year without being eaten...
