I have heard it said that a different colour should not mean a new species. OK, that makes sense. However, upon reading descriptions of several species of Hesperantha, I wonder how many differences are required for a different species. Here are a couple of examples of species with several differences. Hesperantha falcata is either white, scented, evening-flowering or yellow, unscented, midday flowering. Hesperantha pilosa is either white, scented, evening-flowering or blue to purple, unscented, day-flowering. Has anyone grown both kinds of either of these, and would you have thought they were the same species if the labels didn't say so? Diane Whitehead
