Overview
- Germany’s Federal Institute for Risk Assessment cautions that annual misidentifications during spring foraging lead to poisonings, some fatal.
- Autumn crocus is cited as the most dangerous double because it contains colchicine; lily of the valley and spotted arum are additional toxic lookalikes.
- The garlic smell test is unreliable after multiple leaves are handled, so authorities recommend buying from controlled sources or cultivating at home.
- Foragers face bans in protected areas and private forests, with fines reported up to €50,000 in Hamburg and €10,000 in Rhineland-Palatinate; only small personal-use amounts are generally allowed under the hand-bouquet rule.
- Gardeners are advised to plant in March only after night frosts end, use nursery-grown seedlings in shaded, evenly moist sites, skip harvesting in year one, and expect low maintenance once established.
