Curly Kale

Kale plants produce a rosette of elongated leaves with wavy to frilled margins. The leaves are typically blue-green in color but can also be light green, red, or purple, depending on the variety. In a long growing season the main stem reaches a height of 60 cm (24 inches) or more.

The plant may be harvested by cutting off the entire rosette before the stem has elongated, or (especially in areas with long, cool growing periods) the individual lower leaves may be removed progressively as the main stem elongates.
