Know before you buy
Being open-pollinated means that if you allow the plant to go to seed, the resulting seeds will grow plants that are true to the parent variety. This makes it a great choice for gardeners interested in seed saving.
Yes, this is a dual-season variety. It is well-suited for both spring and fall planting, allowing you to take advantage of cooler growing temperatures in both seasons.
You can expect to harvest your first heads approximately 60 days after transplanting. Because this variety produces generous side shoots, you will have a long harvest window beyond that initial 60-day mark.
After thinning, you should space your plants 12 to 24 inches apart. If you are planting in rows, keep the rows between 18 and 36 inches apart to ensure adequate airflow and room for development.
While it thrives in full sun, it can tolerate partial sun conditions. For the most robust head formation and highest yields, prioritize a location that receives at least six to eight hours of direct sunlight daily.
Umpqua broccoli seeds have a viable life of approximately three years when stored in a cool, dry, and dark location. Ensure the packet is sealed tightly to maintain the 80% minimum germination rate.
