Need to germinate seeds of Fritillaria frost?
Some do and some do not need frost to germinate. We sow all ours and set them outside in open frames until they germinate and only then do we take them into the alpine house if they germinate very early in the year - in case of late frosts and to make it harder for the slugs to find them.
If they germnate when better weather has arrived they can mostly stay in a frame.
