Perxi':tian'as 



This strain was originated b\' M. Pernet-Ducher liy erossinu," 

 Antoine Dueher, a H\brid Perpetual rose, with Persian N'ellow, 

 a variety of Rosa foetida. As we have not been able to hnd a 

 source for Antoine lyncher, Cieneral jacciueminot has been 

 ])lanted with Persian ^'ellow to indicate that a H\-brid Perpetual 

 played a jku'I in the ancestry of the Pernetianas. A result of this 

 cross was Soleil d'Or (lOOO), a rose marvelous in color but of can- 

 tankerous temperamert, which amazes us by growing fairly well 

 here. Combination of tliis variety and its progeny with Hybrid 

 Tea roses ga\'e us the Pernetianas, some of which, by reason oi 

 freciuent intercrossing, are ]iractically indistinguishable from 

 Hybrid Teas. Because of this only the earlier introductions — 

 Beaute de Lyon (P)IO) (unnanK>d seedling X Soleil d'Or), and 

 Juliet (1909) (C;a])lain Ha\\vard X Soleil d'Or) are included in 

 this group the remainder of the Pernetianas being planted 

 among the Hybrid Teas. 



The amalgamation of Rosn Joetida with H. T. roses greatly in- 

 creased their color range and, unfortunately, their susceptibility 

 to leaf diseases. 



DWAKI'^ Poi.YANTIlAS 



The center row of beds contains Hybrid Perpetual roses with 

 a border of Dwarf Polyanthas. Beginning at the north end, we 

 have R. multiflora \'ar. and Fabvier (representing chinensis) to 

 suggest the probable parentage of the Dwarf Polyanthas. just 

 how this group originated is not \-ery clear. The probabilities 

 are that some of tliem were the result of crosses between chinensis 

 and its varieties with nndtiflora forms; some are ])robabl\' seed- 

 lings ot iiiidliflord and Wichuraiana climbers (with ])ossibly chinen- 

 sis in their make-up), which developed a dwarf habit; and some 

 are bud sjiorts or muteilions of climbing roses. An example of 

 the latter mode ot orit^in is lu-ho, which is a bud sport of the 

 climbing rose TausendsclKMi. It is recorded that Paciuerette, the
