Variety and background

Purple Romagna is an Italian globe-artichoke selection recognized for purple-tinged buds with green tips and silvery foliage. The supplier stock identified for this product is sold as Purple Romagna. The former store label used Romanesco; the page now follows the supplied stock name without asserting that every strain sold under those two names is genetically identical. Globe artichokes belong to the cultivated artichoke group of Cynara cardunculus, also widely listed as Cynara scolymus.

Sow and grow

Start indoors 8-10 weeks early, 1/4-1/2 in. deep. Germination takes 10-21 days at 70-85 F. Established seedlings benefit from 1-3 weeks below 50 F; protect from freezing. Space 24-36 in., rows 3-5 ft. apart, in fertile, drained soil. Water deeply.

Season care

Grow in fertile, moisture-retentive soil that still drains freely. Established seedlings benefit from a cool period: the supplier recommends 1–3 weeks below 50 °F, while protection from hard freezing remains important. First-year flowering is influenced by plant age, chilling and climate. In mild-winter areas, protected crowns can return for several years; cold regions may need annual culture or additional winter protection. Leave plenty of room for the broad leaves.

Harvest and use

Cut firm, closed heads with 2-3 in. of stem; refrigerate and use promptly. First-year flowering depends on chilling and climate; full production may take another season. Overwinter protected crowns in mild regions. Seed-grown offspring can vary.

Saving seed

Allow several healthy plants to flower when saving seed rather than harvesting every bud. Artichokes are insect-pollinated; isolation from other flowering artichokes or cardoons helps maintain the selection. Let flower heads mature and dry before gathering seed. Seed-grown offspring may vary. Dividing healthy established crowns is an alternative when preserving an individual plant’s traits matters.

Common problems

Poor drainage can cause crown and root rot. Aphids and slugs may damage young growth. Severe cold can kill unprotected crowns, while inadequate chilling may delay buds. Judge watering by the soil and avoid burying the crown in constantly wet mulch.

Frequently asked questions

Is Purple Romagna perennial?

It is a tender perennial, best overwintered in mild regions; the supplier lists zones 8–11.

Will it make buds the first year?

It can, but flowering depends on establishment, chilling and local weather. The supplier’s 85–100-day figure refers to established plants, not a guaranteed harvest from newly sown seed.

When should I cut an artichoke?

Cut firm, tightly closed heads with 2–3 in. of stem before the bracts spread. Refrigerate and use promptly.

What happens if I leave a bud?

It opens into a large purple flower useful for ornamental display and pollinating insects.
