About Rapeseed
Brassica napus × rapa, a hybrid between rapeseed and turnip, is an annual or biennial herbaceous plant from the Brassicaceae family, primarily cultivated for its oil-rich seeds and, in some varieties, for its edible leaves. It features branched stems with lobed basal leaves and smaller upper leaves, culminating in bright yellow flower inflorescences. It is ideal for extensive cultivation in agricultural fields or as a cover crop.

Care tips
This plant thrives in full sun, requiring at least 6 hours of direct light daily for optimal development. Watering should be regular, keeping the soil consistently moist but not waterlogged, especially during flowering and seed development. It prefers well-drained soils, rich in organic matter, and with a neutral to slightly alkaline pH. A common mistake is late sowing, which can significantly reduce seed yield.
