The plant is of medium height. Leaves are large, green, with characteristic weak blistering and fine serration. Ray florets are yellow. The head is characterized by a semi-pendulous shape and a straight stalk.

The hybrid belongs to early-ripening varieties with an early flowering period. The main agronomic feature is resistance to tribenuron-methyl group herbicides, which allows the use of ExpressSun technology during cultivation.
