I have only 1 NOID blue baptisia that I enjoy very much for it's blue green leaves, even after the blooms fade. Because it does tend to splay in the middle during the summer, I cut mine back to a managable size to avoid that and give it plenty of room. It needs to be treated as a large shrub (up to 4 ft.) that dies down after frost, not as a small or medium herbaceous perennial, as planting info will have one believe. Can anyone tell me if it can be divided successfully? I heard that it has a taproot and divisions don't survive.
