The plant is potted in stones. I did this because it is a material that will not decay under the combination a hot rainy summer season with daily rain showers and regular nitrogen fertilization that can turn other media to slush in a single season. This plant has not been bothered by the usual culprit, which are slugs and scales. I like the fact that it produces many stems during the growing season.
An unexpected problem is that since the plant is exposed to full sun during the morning, all the stems point to the side of the pot that gets the strongest light. I will move the plant to a spot where it gets a lights from all sides during the day. Also the stems are beginning to become crowded in the pot which means that I will have to repot them, something I dread to do to large specimen plants because some resent when you damage their roots and might sulk for a while or die even if you are extremely careful not to damage the roots during the repotting.
