I know about lupins. Generally many bush types need the seeds to be scarified. Meaning the seed coats have to be cracked in order for water to get to the seed inside ( cotyledon?) You can either take a nail file and scratch the seed coat or you can try this method. Boil water in a saucepan. Allow to cool for a minute. Drop the seeds right into it. That usually cracks the seed coat or you can soak them for a few days ( which is what i did. My seedlings damped off before they got big enough) Or take a wooden mallet and pound the seeds just till the seed coasts crack. Some times the annual lupines will start to grow if left outside in the rain ( like the native monterey area lupine, sky lupine. Sorry i dont know the latin for that one) BJ
