Cardoon 'Artichoke'

Cardoon Artichoke (Cynara cardunculus var. scolymus)

Cardoon Artichoke captivates with striking, architectural foliage and dramatic, globe-like flower heads that bring bold texture and sculptural elegance to garden beds or Mediterranean-inspired landscapes. Its silvery-green, deeply lobed leaves provide a stunning backdrop for pollinator visits, while the thistle-like flowers—reminiscent of artichokes—add height and a touch of drama to mixed borders. This ornamental relative of the edible artichoke pairs beautifully with tall cosmos, golden yarrow, or soft lavender sage, offering contrast, structure, and rustic charm.

A favourite for bees and beneficial insects, Cardoon Artichoke enriches the garden ecosystem while making a statement in floral arrangements or dried displays. Hardy, drought-tolerant, and visually commanding, this striking plant adds a timeless, slightly whimsical sophistication to both contemporary and cottage-style gardens, bringing texture, intrigue, and enduring elegance to any outdoor space.

 Moderately challenging.

HOW TO GROW:
Transplant (recommended): Sow two seeds per pot and keep them moist in a warm place until they germinate, which typically takes 10–21 days. Once the seedlings have emerged, thin to one plant per pot. Harden off seedlings by gradually exposing them to outdoor conditions for 7–10 days before transplanting into the garden about two weeks after your average last frost date.

Direct Seeding (alternative): In regions with a long growing season, you can sow seeds directly outdoors after all danger of frost has passed.

Pinching and Support: Pinching is not necessary for cardoons. Staking may be required for tall varieties, especially if they are exposed to wind.

Soil Preference and Watering: Cardoons thrive in full sun and prefer rich, well-drained soil. Keep the soil consistently moist, especially during germination and establishment. Once mature, they are relatively drought-tolerant but will produce better with regular watering.

Fertilizing: Amend the soil with compost before planting. You can apply a balanced fertilizer every 4–6 weeks throughout the growing season to encourage strong growth.

Other Tips: Cardoons need a cool period—approximately 10–11 days below 10°C  to induce flowering in the first year, but they will not survive a hard frost. Seeds can also be germinated between damp sheets of paper towel before planting.
