About Cardoon
Cardoon (Cynara cardunculus) is a bold Mediterranean perennial relative of the artichoke, grown for its dramatic silvery-grey arching foliage and tall spikes of violet thistle-like flowers in summer. Hardy in NE Florida zone 9b, it dies back briefly after flowering before re-sprouting. Best harvest of edible stalks occurs in cooler fall and winter months. Starting at $39.95.

Care essentials
Light
Requires full sun — at least 6–8 hours of direct sunlight daily. In NE Florida's heat and humidity, good air circulation around the plant is important to minimize fungal disease risk.
Water
Keep soil evenly moist while establishing; mature plants tolerate brief dry periods but produce best foliage with consistent moisture. Avoid waterlogged conditions. NE Florida's summer rains are generally adequate with occasional supplemental watering in dry spells.
Soil & Fertilizer
Plant in fertile, well-drained soil with good vertical depth for the taproot. Amend NE Florida's sandy soils generously with compost. Apply a balanced fertilizer in early spring; ensure good spacing for airflow to reduce humidity-related fungal issues common in Florida summers.
