Walking stick kale is a tall biennial to short lived perennial brassica grown for its upright woody stems and leafy growth. It is adapted to cool temperate climates and performs well in well drained fertile soils with consistent moisture. The plant develops elongated stems over time, which can be used traditionally as walking sticks once dried. It is suitable for garden beds, open plots, and cool season cultivation where extended vegetative growth is possible.
