Plant labeling supplies very general care and
planting instructions. I'm guessing that*your hostas are shaded by taller plants in your
gardens. Also, climate plays a part. I live in the high desert west where summers are brutally hot. Even plants labeled "full" sun literally can't stand up to the heat here. As with any other pursuit, gardneing lends itself to experimentation. if a plant flourishes where we plant it, that's great, if not, we try again. (So many plants, so little time...
