Colza

Colza, scientifically known as Brassica napus, is a hardy plant native to France and commonly found in its habitats. This annual or biennial forb/herb thrives in full sun to partial shade with moist soil, making it adaptable to various conditions including light (sandy), medium, and heavy (clay) soils. It grows up to 1.2 meters tall and is known for its edible parts—leaves, seeds, and stems—which can be harvested. Colza's versatility extends beyond just being an ornamental plant; it is also cultivated for its edible qualities, with its seeds often used as a substitute for rapeseed oil. Its light requirements of 6-9 hardiness zones ensure it can grow in diverse climates across its native range and beyond.
