The plant has a semi-erect rosette of medium-sized leaves. The leaves are green, have slight puckering, medium-intensity waxy bloom, and a slightly wavy leaf margin. The head is characterized by a whitish color in cross-section, and the internal core is of medium or short length.
The hybrid shows resistance to Fusarium wilt. The heads can remain in the field for up to one month after ripening without the risk of cracking. The produce is intended primarily for fresh market sale; the marketable head yield is about 95%.
