(Intermediate to long day) 110 days. [1890 Italian heirloom via WA state.] This is the sweet onion for gardeners in the Mid-Atlantic and Northeast who have trouble growing short day Vidalia types. These onions are more cold hardy and can still produce large onions with sweet white succulent flesh in soil enriched with plenty of compost or other organic matter. Large 4-6 in. bulbs with light brown skin and upright necks that dry down nicely. Pkt.
