Ice Crystal to me somewhat resembles ice crystals in nature or maybe a . snowflake. At least it puts me in mind of it and I believe that is why it was named that. The flat things you see are rocks. I use rocks on some plants for a couple reasons, to prop up the stem, and if a squirrel decides to dig in a pot I put rock on top to prevent that. Those rocks you see are propping up the plants. I really should just use a stake, but I have more rocks than stakes.
