Upright growth and high yield Anconi RZ is a smooth, dark green endive with a well-filled heart. Its narrow leaf and high yield make it especially suitable for processing. The plants are healthy with upright growth and good field standability when mature. They are very resistant to tip burn and slow to bolt. Anconi RZ is recommended for early summer, summer and early autumn in Northern Europe, and summer and autumn in Southern Europe. Anconi RZ is also suitable for organic production.
