Today Esme was helping her mother with a Christmas tablecloth. It has Christmas stars (Poinsettia, Mexican flame leaf, Noche Buena (Euphorbia pulcherrima)) for decoration, and holly leaves. Esme asked me if I knew that the Noche Buena is a native plant of Mexico, which I didn't, even though I have seen the plant growing in the wild here, quite tall even. I did know though, that what most people call the flowers are actually colored leaves, and that the actual flowers are easily overlooked.
I looked up the Poinsettia in the Wikipedia, and checked the entries in the flowers of Mexico, and found a flower I know: the flower of Dead (Cempasúchil, Flor de Muertos), which is used a lot for decoration purposes on the Day of the Death (Día de los Muertos, not to be confused with Halloween), 2nd of November.
