Perennial Tree Kales/Collards/Broccoli
Perennial tree kales, collards, and broccoli are remarkable brassicas that provide continuous harvests of nutritious greens for years without replanting, making them cornerstone plants for food forests and permaculture systems. Unlike annual kale and collards that bolt and die after one season, these vigorous perennials develop woody stems reaching 4-8 feet tall, producing fresh leaves continuously for 5-10 years or more.
The tender growing tips and young leaves offer excellent flavor for fresh eating, cooking, and smoothies, providing vitamin-rich harvests nearly year-round in mild climates and through much of the growing season in cold regions. These hardy plants tolerate frost and continue producing through winter in many areas, delivering fresh greens when annual vegetables have long since finished. Tree collards and kales establish quickly, require minimal maintenance beyond occasional harvesting, and naturalize into productive specimens that suppress weeds while building soil.
They thrive in full sun to partial shade, making them ideal for understory plantings beneath fruit trees where their deep taproots mine nutrients without competing with shallow-rooted crops. Easy to propagate from cuttings, these plants can be shared and multiplied throughout the garden. Hardy across USDA Zones 7-10, with some varieties tolerating colder conditions, perennial brassicas are essential for sustainable edible landscapes seeking continuous leafy green production with minimal annual labor.
