Tree Peony, Rosina, A New Era in Tree Peonies
The Farr Collection of Tree Peonies, right now, includes 247 varieties which have attracted thousands of admiring visitors since 1916. Seldom, however, have we been able to permit sales at less than $10 per plant because we rarely possessed more than two or three plants of the most admired varieties, and it was more important that these "parent" plants be conserved for future propagating purposes than to sell them at high prices.
For some years now, we have been propagating only the "Best 50" varieties which were selected after fifteen years of collecting, testing, and observing, and which will be introduced throughout coming years. It hardly seems possible that at last we possess an ample supply of a Tree Peony beside Moutan and one of the "Best 50" as well; for while Tree Peonies are easy to maintain, it is difficult and costly to produce new plants.
There are 380 field-grown and bloom-tested plants of Tree Peony ROSINA now in our nursery rows after two years of unprotected field-exposure to parched summers and zero winters. Thanks is due to visitors who [illegible] indicated a preference for the delicate flesh and pink tints and who, accordingly, encouraged our maximum propagating effort toward these sorts.
ROSINA is of medium growth-rate and exceptionally hardy, healthy, and free blooming, as are all of the "Best 50". The blooms are large, semidouble, delicate flesh-pink, with crêpe-paper-like petals. It is two weeks earlier than the herbaceous Peonies and develops more fully double as plants become older. The prices are the lowest we have ever applied, and not much more than the prices in Europe or Japan today. 
6 to 8 inches, 3-year plants...$2 50 each

Comments on and corrections to this list are invited. Information is particularly desired on the varieties believed to have been originated in Italy by Casaretto, Burdin, and others, for all attempts to learn something of these men have ended in failure.

The Tree Pæony. 
...For the last twenty years or longer we have had to look to our French neighbours for new sorts of Tree Pæony, for since they have taken the work of hybridising and raising seedlings in hand they have supplied us with all the finest sorts.  Until now the list is long- too long, in fact, for names are given where very shadowy differences exist.

The Best Tree Peonies.
The following list contains some of the very best varieties of tree Peonies or Moutans at present in cultivation; I obtained it from my friend M. Charles Verdier, of Paris, who makes Peonies his special study; among them, as will be seen, are few novelties, but M. Verdier states that the newer varieties are generally inferior to the older kinds:
Rosini [sic], a semi-double, brilliant rose-coloured variety
