Rue has corms/bulbs?
I found several small plants in the woods and the leaves look like a rue (thalictrum) to me. The plants are growing in rather dry full shade, are only about 6 inches tall, and are native & hardy in zone 4, Minnesota. I was surprised to see small corms or bulbs at the base of the plants, under the soil. I've not noticed anything like that with my full sun, tall meadow rue. Is it a true rue or an imposter?
