TWILIGHT THORNLESS BLACKBERRY, a revolutionary new blackberry variety! The best of eastern and western blackberry genetics has been crossed to create Twilight, a new distinctive, hardy, thornless, semi-erect blackberry variety out of Oregon State! Originating from seed produced from a cross between the thornless female blackberry plant ‘Ouachita’ (U.S. Plant Pat. No. 17,762) and the thornless, male parent blackberry plant ‘ORUS 2867-4’. This new blackberry cultivar is known for its outstanding blackberry jam flavor with hints of floral honey notes!!! It is fairly early ripening for a semi-erect blackberry, and it produces large sized, very firm berries with durable, glossy midnight purple skin and a distinguished crisp textured "pop" when eaten! Less bleeding and handles better than other blackberry cultivars. Superior in not only flavor and size compared to Chester and Triple Crown but also vigor. High yields are borne on fully thornless semi erect canes in mid-season. Self-fruitful.
