Have you ever divided a mature Bleeding Heart? Today I endeavored upon moving a big one, and was shocked at the huge mass of fat, brittle roots! It was so big this spring that it nearly covered the path that leads to my entry, so it had to be moved. The funny thing is that I had this idea to move it 3 years ago, and thought I had done just that, but apparently I had left pieces of root in the ground that decided to grow. They ended up being a lot bigger than the original plant. I ended up with 4 large divisions and got them replanted in homes I think will be better suited.
This pic was taken last year, I think it doubled in size this spring.
