Dark Blue Garlic seeds grow into a cool-season perennial plant that is commonly cultivated as an annual in home gardens and raised beds. The plants develop upright, narrow foliage and a clump-forming growth habit that performs well in temperate climates with cool to moderate growing seasons. Garlic establishes best in full sun and fertile, well-drained soil, where consistent moisture supports steady growth. This type is suitable for garden beds, small plots, and seasonal planting schedules.
