1. Is it necessary to let the seed pods of Lupine dry on the stem before preparing them for planting?
2. Do you open the seed pod and remove the tiny seeds from within and plant them or do you plant the entire seed pod, if so, are these tiny seeds the ones that are supposed to be ruffed up or is it the large seed pod that is supposed to be ruffed up and then soaked in water?
3. What is a good source to get different types of Lupines?

Lupines produce flower spikes and each individual flower is capable of developing a seed. Therefore, you'll find many seeds in one flower spike. Wait until the spike turns tan, indicating the seeds are ripe, then cut it from the plant. Hold it upside-down in a paperbag and shake to dislodge the seeds. The seeds are each encased in a hard outer shell, and are 1/4 to 1/2 the size of a garden pea. Do not open or break individual seedcoats. Soak the seeds for 24 hours or chip the seed coats to help the seeds absorb moisture. Then sow 1/8" deep in moistened seed starting mix. Seeds should germinate in 14-60 days when kept at 55F - 65F.
