For generic information on the garden Carnation and Picotee see Dianthus caryophyllus L.  Wilson’s ‘Plus Perfect’ is a light edged purple picotee, probably introduced in 1841.  [Gard. Chron. 1841].  ‘A great favourite with many, being above the average size, with a fine broad and pure petal; its slightly serrated edge will always prove a serious drawback.’  [Gard. Chron. 1846].  ‘This is a very beautiful Picotee, of the purple light-edged class. the white is of uncommon brilliance, and the lacing entirely confined to the edges of the petals.’  [FC p.218/1842].  ‘Light-edged, purple picotee: pod good and large; petals large and broad, but a little serrated; ground pure; edging fine and very distinct.’  [FC p.79/1849].  ‘An old flower, but a good one; the edging light and delicate, white good, rather difficult to increase, as its habit is not robust.’  [BF p.220/1844].
