Lynn,
NO arachnoideum in Oddity for sure. The 'Albidum' parent plant is ether a pure tectorum or X wulfenii. I have never seen anything I would call great winter coloring in it either. Certainly nothing special to be noted.
Hope that helps!
Am not sure where the dates of introduction of these plants was put into the data base. It mist have come from one of the European lists.
