Calandrinia grandiflora is a cousin to the purslane and portulaca we all love here Caroline.
It is part of the family tree of the Portulacaceae family and sometimes people call it rock purslane too. The leaves are grey-green and the blooms are higher on taller stems.
Purslane/portulaca is a variety of plants that gets confusing because they are kin but not the same but still, are are succulents. People are often calling everything purslane or portulaca but usually I say nothing unless they want to know the real plant.
You know how people call anything with narrow petals groupsed aroudn a center a daisy? That is what happenes with purslane.
Cisanthe grandiflora is the same as Calandrinia. Just another name for it.
