Sea holly (Eryngium maritimum) organic

Biennial wild flower for dry, lean locations in the sun. Cold germination: Sowing time outdoors at the beginning of spring or in autumn. Alternatively, artificial stratification is possible. Mix the seeds with moist sand in a plastic bag. The bag must be kept warm and moist (approx. +20°C) for the first 2-4 weeks and then placed in the refrigerator where it should remain at a temperature of +5°C for 5-6 weeks. Then remove the plastic bag and observe regularly at room temperature whether the seeds germinate. Then prick the seedlings into pots and plant them out after the last frosts in mid-May.
