For "shower" bouquets, festoons, and table decorations it is useful to have certain plants with slender trailing stems and foliage that will not soon wither. Amongst the best plants for this purpose are Asparagus Sprengeri, A. plumosus, and A. plumosus nanus (all known as Asparagus "Ferns"), A. medeoloides (or Myrsiphyllum asparagoides) far better known to florists as "Smilax". A great trade is done in the trails of these plants, and some growers make a speciality of their culture.
