Found this info - seems to be grown in USA:
Semi-erect, large, firm berries with good keeping quality. Virus yested principally in Maryland and Ohio
A true thornless variety (i.e. should not revert like my canes did) When tested for anti-oxidants at Fruit Laboratory, Beltsville, Maryland USA, The 'Hull Thornless' cultivar contained the highest levels, whereas 'Black Satin' consistently had the lowest activities for all the enzymes tested in this study. In USA they are slow to break bud and remain dormant later into the spring.
Can't find anything on taste though!
