The Amsterdam Heirloom Carrot variety is one of the finest carrots for the baby bunch or early carrots. It has a maturity date of 50 days. With a high germination rate, it also is one of the best bulk Heirloom garden seeds we carry. These will grow very uniform with nice tops and have an almost dual orange color to them. They will thrive in any zone here in the states; they will do awesome in cold frames. For an extra early harvest, these can be harvested in 40 days for baby carrots. We recommend planting every few weeks from early February to late August and year round in zones 7 or higher. Happy growing!!!
