The flowers are supposed to be upright! This plant is so often in a pot in less than all day sun, with sideways flowers.
It's so strange that the blooms would come from lower parts of the plant, then cover part of itself with open blooms. Do the blooms usually occur on new growth, toward the outside of the patch? That would enable the blooms to lean on the ground. They're so heavy.
Do you ever see seeds on this kind of plant where you are?
