Tree: high yield from floricanes, low yield from primocanes; primocanes green, sparse purple spines largely restricted to basal portions; primocane production moderate with frequent branching; winter hardy. Reaction to spur blight similar to Boyne; less susceptible to cane spot than Boyne, susceptible to tomato ring spot virus; susceptible to infection from pollen transmission of raspberry bushy dwarf virus.
