Brassica - oleracea
An old-fashioned early favorite Introduced by H. Hartman & Company in 1909. Originally from Denmark, it has been a gardener's favorite for a century. Compact heads are 6-8" diameter and 3-4 lbs., tightly wrapped and perfect for small gardens. These compact heads are sweet for fabulous coleslaw, salad, or sauerkraut. Copenhagen Market became the standard of excellence for many store-bought varieties that were developed after it! Adaptable to a range of climates. Resists splitting and stores well.
When to plant outside: Early spring, 3 to 4 weeks before average last frost - or in late summer, 10-12 weeks before average first frost. Late summer is best where summers are hot. In zone 8 or warmer, sow early fall for winter harvest.
When to start inside: 4-6 weeks before transplanting outside
Special Germination Instructions: Easy to start from seed. Thin seedlings by pinching off plant at soil surface, thus decreasing damage to other seedlings. Rotate crops, so you don't grow any member of the mustard family (such as bok choy, broccoli, cabbage, kale, etc.) in the same place more than once every 3 years.
