This is generally grown as a perennial in mild areas and as an annual where ground freezes although a good winter mulch may help overwinter in hard frost areas. Price for 6 seeds.
These stately architectural plants need plenty of room and make wonderful specimen plants in your borders as well as your veg plot. This improved strain has excellent quality tight compact good sized heads. Harvest these before the bracts open. Cut the top one first, then the secondary ones as they mature.
Pollinating insects will be very happy if you leave one flower bud to open fully while harvesting the rest.
