Just wanted to update the information on this sedum. Research shows that it is sold under several different specie names (S. hakonense, S. hispanicum, S. Hybridum, and I have seen a couple more species names that it can be sold under).
The database information has been changed from S. hakonense 'Chocolate Ball' to S. polytrichoides 'Chocolate Ball'.
My first two attempts at growing this sedum were not successful. I finally figured out that it does not like full sun/drought conditions. This plant has done well for me in morning sun, fast draining soil, but does not like to be kept dry. It likes to be watered on a regular basis. So far the color has stayed a very dark and intense deep chocolate color.
What are your experiences with this plant?
