Sow the seed onto the surface of good free draining compost in individual cell trays or small pots. Cover seeds with a fine sprinkling of compost, grit or vermiculite and water gently,
Keep them outside in a sheltered spot, a cold frame or cold greenhouse is ideal. The seeds need a period of cold to germinate successfully and germination can be pretty slow so keep checking; keep the compost just moist but not wet. Because eryngium are tap-rooted plants the seedlings resent disturbance so thin emerging seedlings to leave just 1 per individual pot or cell.
Grow the seedlings on in cool conditions and transplant very carefully into deeper pots when they outgrow their original cell trays or pots. Plant outside in their final positions once they are well grown, sturdy plants.
