Stock produces dense, fragrant flower spikes in a wide color range, prized as a cut flower for both the look and the scent. It's a member of the brassica family, related to cabbage and broccoli, which shows up in the pests it has to deal with more than in its appearance.

How stock fits zone 6's season

Zone 6b's frost-free window runs about 173 days, from April 25 to October 15. Stock needs about 80 days from transplant to first harvest.
