Characterized by abundant fruiting over a wide temperature range, actively fruits until late autumn. Sun-loving, with medium or above-average branching; exhibits type 2 self-regulation of branching (when high fruit load on the main stem suppresses vigorous growth of lateral shoots). Forms 2-3 to 5-7 fruiting nodes per node. Fruits are ribbed, white-stemmed, bright green, 8-11 cm long; excellent taste and pickling qualities. Hybrid resistant to powdery mildew, olive spot, and common cucumber mosaic virus; tolerant to false powdery mildew.
