A friend took the previous photo of my self-seeded martagons in the spot where she saw the greatest concentration, but I have many more scattered through much of my shade garden. They seem to like to appear in paths so I have many little "fences" to protect them... dangerous to walk in places!
I hadn't really thought about the variation of the plants in this one small section of my shade garden but Rick is absolutely correct.
Here are a couple pictures I took yesterday of individual plants, not the same ones that appear in the group photo
To respond to Joshua, I have 17 named cultivars in long established clumps. Dalhansonii may be a parent of the red seedlings, and Brotsing may be the parent of the yellow ones, but this is conjecture on my part. I didn't know I had a seedling until the first one bloomed in 2013 and that one looks like dalhansonii which is located about 30 ft. away.
I purchased 17 more cultivars in 2012 and 2013, but those are just now starting to bloom... several never came up at all. Martagons require a lot of patience and sometimes bring disappointment, but are well worth the wait. But nothing has been so rewarding as these self-seeded plants. Mother Nature must have decided that I deserved something special?
