Okay, time for an update on my S. 'Gruenrand'.
The two that were treated with Configure are producing offsets now. The larger of the two treated semps has 4 offsets so far, the smaller has two.
The untreated semp has 6 offsets so far.
Untreated semp with small semp on the left. Sorry you can't see the other offsets on the back side. Soon I should be able to take a photo from above that will show all the offsets.
Sorry, forgot to take a photo of the treated larger semp.
