Instructions: |
Like all lupines, the seed of this one is large and hard. Many soak the seed before planting to soften the seed coat. Others recommend scratching the seed with sandpaper or a file to help the hard seed coat "break" after planting. Nobody does any of this in the wild, of course, so it is not required, however these treatments may hasten development. Once germinated, lupines must form a tap root before blooming well, and this means a preference for sandy or otherwise loose soils. With heavier soils, they will develop, but it will simple take longer. |
