Seedville Cardoon

Yes, you can grow Cardoon as an annual in colder climates. While it is a perennial in zones 5 and 7-10, gardeners in colder regions can treat it as a seasonal plant by planting it in the spring and harvesting before the first hard frost.

Cardoon plants grow quite large, reaching up to 4 feet in height. You should space your plants at least 3 feet apart to ensure they have adequate airflow and room to develop their edible buds.

The plant produces globe-like buds that are similar to artichokes and are the primary edible portion. The stalks are also often harvested and prepared in culinary dishes, offering a unique, slightly bitter flavor profile.

You can expect to harvest your Cardoon approximately 120 to 150 days after planting. Because of this longer growing period, it is best to get them in the ground during the spring.

Cardoon is relatively low-maintenance and prefers average soil and water conditions. They thrive best in full sun, so ensure your planting site receives plenty of direct light throughout the day.
