I'm wondering whether anyone else on the list is growing "black"  
raspberries that have bud-sported over to producing yellowish fruit.   
I have a couple of such plants that I believe to have originated a  
number of years ago in a batch of rooted Cumberland cuttings.    
They're a little more vigorous than the other blacks, have a  
decidedly odd taste that nevertheless goes okay with vanilla ice  
cream, and the fruit has a really unattractive color scheme (imagine  
Gulden's brown mustard with faint streaks of black shoe polish  
running through it), but _darn_ are they productive even in the  
unirrigated acidic weedy and poorly-lit corner to which they've been  
exiled.
