In Maine, we love our lupine flowers, which seem to grow everywhere — even by the side of the road, without any tending. We have three beautiful lupines right in front of our house, and I’m interested in trying to grow lupines elsewhere on our property. But if you want to harvest lupine seeds and grow lupines, you need to work at it.
Later in the summer, the lupine flowers are replaced by lupine seed pods, which look like hairy pea pods. (This is not surprising, because lupines are a part of the bean family of plants.) If you want to harvest the seeds, you need to wait until the seed pods dry out and you can hear the seeds rattling around in the pod. Then you patiently open the pods one by one, free the seeds from the pod, drop the seeds into a storage container — in our case, a coffee cup — and then wait to plant the seeds until the end of the season. If you plant them too early, they’ll be found and consumed by birds and the other hungry critters of Maine. The lupine seeds then need to experience multiple weeks of cold weather before they germinate and new plants can grow.
Unfortunately, I waited too long to do the seed harvest from the plants in the front of the house. By the time I checked them, most of the pods had already burst open and dropped their seeds — and lupine seeds are incredibly tiny and heavy, so I wasn’t going to be able to find and retrieve them from the ground. However, I found some unopened pods, and we retrieved some additional pods from plants along the roadway. With the help of Dr. Science and the GV Jogger, who pitched in with us and enjoyed the simple pleasures of pod opening and seed retrieval, we’ve now collected several hundred of the small black seeds, which I will try to plant this fall.
According to the Mainers, you should try to position the lupine seeds in areas where there isn’t much competition from other plants. In addition, lupines seem to prefer rocky soil — and we’ve got plenty of that. I’ve got several locations in mind where I would love to see some lupine plants take root. I’ll be hoping that some of the seeds avoid the foraging of our neighborhood birds and animals, so that next spring we’ve got a serious lupine bloom on our hands.
