What I should also have said is that placing a plant in any particular family has no bearing whatsoever on the plant as it grows in the wild or in cultivation! A few families may have features that require similar growing conditions for their member genera and species, but for the most part it is the species' own requirements that affect its performance as a growing plant. Families and the higher orders of taxonomy serve the human desire for order and while it is nice to know the relationships betwen families and genera, this has very little bearing on what we as gardeners are trying to do.
