A Mexican umbellifer which was first described only in 1954 by Mildred Mathias. Architectural plants that seem to do well in full sun or part shade with green foliage in the spring turning more olive as the year progresses and taking on pink and purple tints in the summer. They last ages in flower and seem to produce no seed, the flowers are lime green when the first appear but, like the foliage, turn darker as they age. Certainly hardy in the south, may need a more sheltered spot in colder climes.
