Broccoli Imperial F1 Seed

form: RAW
size: 1,000 seeds
Imperial broccoli seed produces high quality, tight dome-shaped heads with small dark green beads. Its heads have excellent post-harvest holding ability and work well for both bunching and crown cut. Imperial broccoli seed performs best during long day growing conditions with moderate heat. Under these growing conditions it is mid to mid-late maturing. Shorter day lengths and cool conditions result in much later maturity.
