The familiar "florists' chrysanthemums" pictured here and so popular this time of year are now in the genus Dendranthema (dendro = woody, a reference to their woody annual stems). Like many other people, the Phactor learned to call the Shasta or ox-eye daisy Chrysanthemum lecanthemum, which is kind of fun to say, except it meant "goldflower-whiteflower". Leucanthemum (leuco = white) is their new genus. Other former chrysanthemums are the pyrethrum daisies (feverfew - long known as a remedy for fevers, and as a source of the insecticide of the same name) are now placed in Tanacetum. And what of the real chrysanthemums? Of the 300-400 species that used to be in this genus, now there are two, both annuals of the Mediterranean region.
