Canadian Mammoth Red Clover

Canadian Mammoth Red Clover – Raw Seed
Cold-Hardy, High-Nitrogen Biennial for Soil Health and Seasonal Forage

Canadian Mammoth Red Clover is a cold-tolerant legume bred for exceptional performance in northern climates. Known for its tall growth habit, rapid establishment, and ability to thrive in shorter growing seasons, this biennial clover variety delivers outstanding soil-building benefits while providing nutrient-rich forage for wildlife.

Canadian Mammoth Red Clover can fix 70–150 lbs of nitrogen per acre, making it a powerful soil fertility booster ahead of nitrogen-demanding crops like corn, brassicas, or cereal grains. Its robust taproot penetrates deep into the soil profile, improving structure, water infiltration, and long-term organic matter levels. The dense canopy helps suppress weeds and protect soil from erosion.

As a forage, Canadian Mammoth Red Clover offers 16–20% protein and is highly palatable to deer, turkeys, and other wildlife—particularly in spring and early summer when other forages may be limited. While it produces abundant top growth, it’s best suited for short-term stands of one to two years, as it does not regrow as well after repeated mowing or heavy browsing compared to perennial clovers.

This seed is raw and untreated, making it adaptable for a variety of management systems, including organic production.
