Blue toadflax (Nuttallanthus canadensis) is native to North America but can now be found across Japan, producing flowers from April to June. The environment has a lot to do with the growth of plants. Blue toadflax growing in full sun are much taller with "chubbier" flowers than those in less sun. My perception of blue toadflax has completely changed from "fragile" to "(unexpectedly) tough" since I saw the chubby ones.
