Have you seen the Anthurium growing on the lava rock? I got several as gifts from LoGees and they are beautiful. Mine finally died. they just sit the rock in water and they are so pretty. I do not know what happened but mine died. It could have been the water. I did not use spring water. I took some cuttings from my stock plant and started them. I thought I may try the lava rock thing, but I just could not see how they kept them in there and growing. They love water for sure, and my cuttings sprouted in water. I have red and pink but they are resting now. They bloomed all Fall and winter.
