🌾 Seed Saving Guide

🟡 Moderate

✅ Open-pollinated — seeds grow true to parent

When to Harvest Seed

Allow one head to fully bloom and dry on the plant — the thistle-like flower matures into seeds.

Processing

Let flower head dry completely on the plant, pull apart to find seeds at the base of each feathery strand.

Seed Viability

Up to 5 years when stored cool, dark, and dry.

Pro Tip

Seeds may not grow true to the parent variety — artichokes vary widely from seed. Crown division is more reliable.
