Organic Onion Ring

Unit price perThe result of a rigorous and deeply human scientific approach, this exceptional red onion was born in the research fields of the University of Wisconsin. For several years, Dr. Michael Havey, a renowned horticultural geneticist, and his team pursued a simple yet ambitious idea: to develop an onion variety with a round, dense bulb and a single center, perfect for producing uniform slices. This project, carefully conducted within the USDA Onion Lab breeding program, embodies an approach rooted in knowledge, patience, and attention to detail.
When the program ended, this remarkable lineage was entrusted to the Gardens of the Ecumene so that it could continue to thrive in the hands of gardeners. Since then, this variety has been cultivated with passion, passed on to a community that has given it a name, a place, and a future in living vegetable gardens.
In the garden, it stands out for its vigorous, upright growth habit, good tolerance to climatic variations, and impressive production capacity. The bulbs that form are firm, glossy, and a deep red, and their finely detailed internal structure makes them easy to cut. In well-prepared soil, it offers excellent consistency and adapts readily to garden plots, whether for individual or community use. It thus embodies the balance between horticultural innovation and the age-old practice of sowing seeds, between high quality and ease of cultivation.
