Howard Wills photo shows mottled purple and green leaves. To me this mottling indicates that this semp is going to change color a LOT during the different seasons and even year to year.Pictures in the other data bases and ours confirm this. The form (shape) of the plant is consistant is all the German sites and most of the photos on ours. Spring Colors photos seem to be of a different plant. Not only is the color not in agreement with the other photos but the form is very different.
jkbingh's photo is also too different in color and form. Semps that display mottling of purple and green/blue at one time of the year usually do not turn solid burgundy/red at another season. This is only my humble opinion. and I could be 100 percent wrong as some things did some pretty extreme color changes this past winter This is why I think that ALL pictures should be dated as they are on Sempervivum Liste
