Popular artichoke. This variety yields over a long period of time, fall or spring, depending upon location. Can be pretty in landscaping with its fountain-like look of silver-green foliage. Flowers great for dried arrangements. Mature height is 3-4 ft. with 5-6 ft. diameter. Cold hardy to USDA Zone 5.
In warm areas, such as California, treat as a perennial and leave for 6-7 years until they need to be divided. In colder regions, artichokes should be treated as annuals as the roots will die with prolonged freezing. Plant 4-6 ft. apart, in rows 8 ft. apart. Non-taxable.
