Organic Canola Rapeseed {Brassica napus} Winter Harvest | Cold Tolerant | Oil Producer | 20+ seeds Free Shipping! Rapeseed Scientific Name: Brassica napus About Rapeseed: Rapeseed (Brassica napus) has deep fibrous root systems and is used for nutrient capture and a subsoiler. This brassica has been shown to have biological activity against plant parasitic nematodes as well as weeds. It has great versatility when it comes to planting because it can be planted in the spring for a summer cover crop, and may also be planted in the fall for a winter cover crop. Because of its hot and cold dual tolerance it can be a better choice than radish’s in some cases. If you are needing a crop that can last through the winter, it is the best choice if more cold tolerance is desired for the blend or for grazing.
