Nantes-type Carrot
Shin Kuroda breaks the summer carrot rules with exceptional heat tolerance that keeps you harvesting sweet, crunchy roots when other varieties have given up. This Japanese-bred improvement on the classic Chantenay type produces five-inch, broad-shouldered carrots in just 58 days, though some sources report harvest times ranging from 58 to 75 days. The vigorous, stump-rooted shape pushes easily through heavy or clay-rich soil where slender varieties often struggle, making it perfect for challenging garden conditions.

This variety shines where others falter, thriving in summer heat that would stress most carrots. The broad shoulders and sturdy five-inch roots muscle through tough soils with ease, while the remarkably high sugar content and tiny core deliver exceptional flavor. Strong, tall tops make harvesting a breeze, and the excellent storage qualities mean you can enjoy these sweet treats well into winter.
These carrots excel fresh from the garden, prized for their remarkably juicy, refreshing crunch that makes them unsurpassed for raw snacking or slicing into salads. The high sugar content and tender flesh with minimal core also make them excellent for cooking, while their excellent storage qualities ensure fresh carrots through the winter months.
Not recommended as root disturbance stunts growth in carrots.
Sow outside 2 to 4 weeks before your average last frost date when soil temperature reaches at least 45°F, ideally 60-85°F. Plant seeds 1/4 inch deep and continue successive sowings every 3 weeks until mid-summer. Seeds can take 10 days to germinate.
Harvest begins at 58 days when roots reach 4-8 inches in length and develop their characteristic broad shoulders. The strong, tall tops make harvesting easy by providing a good grip for pulling. For winter storage, plant carrots about 100 days before expected fall frost to ensure proper root development.
