Growing Heirloom Artichokes
Heirloom artichokes are produced from rootstock and grown perennially, meaning they are farmed and produced in the same field for many years. As with most perennial crops, our Heirloom artichokes require an annual pruning or “cut back” cycle where the plant is cut down to bare ground. A few weeks following cut back, multiple vegetative shoots will emerge from the rootstock and initiate the artichoke production cycle. Artichoke buds will begin to produce in the base of each shoot; the shoots will transition into stalks which can support eight to ten artichokes each.
Initially smaller than the size of a pea, the artichoke buds will continue to grow larger until reaching the proper size for harvest. The time frame from primary bud formation to harvest can take several months. Heirloom artichokes consistently produce new shoots throughout their growing cycle. This characteristic enables us to harvest our Heirloom variety on a regular basis and provide a wide assortment of artichoke sizes each time we harvest the field.
- Heirloom artichoke plants have a lifespan of 12 to 15 years; some of our plants have been growing for over 20 years.
- A typical Heirloom artichoke plant can yield approximately thirty artichokes per year.
