Thought I'd add some of my own after all the ones I have seen recently
D. macrantha. 3rd year from seed
D. ramellosa. 2nd year from seed
D. stolonifera. This was actually my first tuberous. I started with a tuber about the size of a BB. The tubers for these guys this year were just about the size of a full sized jelly bean
