ERYNGIUM PLANUM 'BLAUKAPPE'
This is the most metallic blue of all "sea holly" flowers. Heart-shaped leathery leaves surround these exotic blooms which make superb cut flowers, and when dried out, retain their colour indefinitely.
Sow seeds IMMEDIATELY you receive them, at any time of the year, they depend on having several months, sometimes up to a year in cold, damp compost, (NOT DRY IN A FRIDGE) before they will germinate. Keep the seed tray moist in a cold greenhouse or shady corner and do not discard. These fresh seeds can be very slow to germinate but do not use any artificial heat in an attempt to germinate them as it may simply disrupt their germination mechanism causing them to enter even deeper dormancy.
