Boiling Water Over Lupine Seeds - Knowledgebase Question

Cloquet, MN
Question by Blaisers

I have had trouble starting lupines from seeds. Recently I was told to either boil them for a while or to pour boiling water over the seeds to soften the shell. Will this work? Do you have more details for this or another method?
Thank you!! Theresa (We have a VERY short growing season!) Do they need to be started indoors ahead of time, or can they be started directly outside?

I have had the most success with starting lupine seeds by scratching the seed coat. All I do is nick the seed with a nail file or sharp knife. The seeds are then planted in sterile, soilless mix to which I have added a few handfuls of sand. Because you do have such a short growing season, it probably is best for you to get a head start on things by starting your seeds indoors.
