Thanks Walter. This is a wealth of information. Side note: I smeared a lot of 
Satan's Mistress pollen this year. Did not know it to be arilbred, just liked 
the black and amount of pollen (intuitive hybridizing). Will watch seedlings 
if any for dormancy. Sometimes easy to confuse dormancy/semi-dormancy with 
lack of vigor.
