Roscoff Pink Onion Keravel - Organic
$4.49
Unit price perOriginating in northern Brittany, France, the Roscoff pink onion has been shaped by sea winds and coastal soils. The 'Keravel' variety, offered in organic farming, continues this story in today's organic vegetable gardens. Its pinkish bulbs, round to slightly flattened, grow in neat rows and color the garden from late summer onwards, like small suns with coppery reflections.
In the garden, it's a reliable plant: upright foliage, consistent growth habit, and easy harvest time when the leaves gently bend. When properly cultivated, it produces good-sized bulbs with pale pink flesh, prized for their sweet and fragrant flavor. In a thriving garden, the onion structures the beds, complements neighboring crops, and contributes to a respectful approach to soil and the natural cycle of the seasons.
