Rosario is a medium-early onion variety with a vegetative period of about 80 days, distinguished by high yield and resistance to unfavorable conditions. The plant has lush, dark green leaves, and the stem tip is small, oval, and pinkish. The onion has a delicate taste, especially valued when fresh and when fried. This variety adapts well to drought and low temperatures, preferring cultivated loamy soils and light loams.
Rosario is characterized by rapid development due to large bulbs of size 17/18, which ensures powerful and abundant flowering. The plant forms dense inflorescences with a beautiful symmetrical shape, making it attractive not only for growing in a vegetable garden but also for use in decorative purposes. The onion is suitable for creating color accents in borders, mixed borders, and pots, and can also be used for forcing and cut flowers.
A feature of the variety is its high resistance to various climatic conditions — it withstands frosts, heat, rain, and short-term drought well, while being almost immune to diseases. Flexible branches bow under the weight of inflorescences, creating an effective fountain silhouette, which should be taken into account when planning plantings. Thanks to these qualities, Rosario is widely used in landscape design for decorating slopes, living hedges, and the background of mixed borders, adding elegance and freshness to the garden.
