Branching Bush Kale is a type of kale known for its hardiness, productivity, and good taste. It has a bushy, ragged look. Some of the many common names, including "perpetual kale" and "perennial kale" signify that this leafy green vegetable can live on and be harvested for multiple years (5-6 years, precisely) provided it is protected from frost during the winter. Interestingly, the subspecies rarely blooms, which means no seed production, contributing to its rarity in gardens. Luckily, it is easily propagated from cuttings.
