Mertensia simplicissima

Mertensia simplicissima

Family boraginaceae
Life cycle perennial (Z6-8)
Flowers blue (summer)
Size 6"
Light sun-part shade
Cultural notes well-drained soil
From seed self-seeds in our garden
detailed seed-starting info below

With foliage much bluer than its American cousin Mertensia virginica, this perennial is native to Japan. After growing it successfully on the edge of our moist shade garden (where it receives part sun), I learned that it prefers well-drained soil – sometimes it's better to be ignorant. But now that I know, I'll probably give this a try in our rock garden as well.
