Are Mertensia and Sasa plants from differing genuses?
Mertensia Mertensia is a genus of flowering plants in the family Boraginaceae. They are perennial herbaceous plants with blue or sometimes white flowers that open from pink-tinged buds. Such a change in flower color is common in Boraginaceae and is caused by an increase of pH in the flower tissue. "Mertensia" is one of several plants that are commonly called "bluebell". In spite of their common name, the flowers are usually salverform (trumpet-shaped) rather than campanulate (bell-shaped).
Senegalia Senegalia (from Senegal and "Acacia senegal" ) is a genus of flowering plants in the legume family, Fabaceae. It belongs to the subfamily Mimosoideae. Until 2005, its species were considered members of "Acacia." The genus is still considered polyphyletic and will require further division. "Senegalia" can be distinguished from other acacias by its spicate inflorescences and non-spinescent stipules.
