White Varieties
Le Cygne (Lemoine).  9.9.  White.  There are several peonies that when the year comes that they are at their best are unsurpassed in their perfection of form and their general all around beauty.  Le Cygne is such a flower.  Among the true whites, it lies between Le Cygne and Kelway’s Glorious as to which is the most beautiful flower.  Le Cygne is purer in its whiteness and more perfect in the arrangement of its petals and in its general form.  Kelway’s Glorious, although an immense flower in size, still has such a daintiness of construction that its appeal is irresistible.  So it is a matter of taste only as to which flower is the better.  Le Cygne is a flower of the purest white with no tracings of color.  Its form is absolutely perfect.  An immense flower of true rose type that as a rule is a wonderful show flower.  Early to mid-season in blooming.  The great blooms are held erect on strong stems of medium height.  Produces large typical blooms on one year plants.  One of the greatest of all show flowers.
