manure. They do well in either sun or shade, and are well suited to 

 front borders of shrubberies, open places, along walks, or mixed bor- 

 ders. A t(i|) dressing of manure in niid-sunmier with the addition of 

 a little ii<jui(l manure will hel}) much. When once well estaljlished the 

 roots should remain undisturbed for several years. The Paeonies of 

 the tree section are likely to start early and may be injured by late 

 spring frosts in the northern states unless protected at times of such 

 danger. These do well in [)ots under glass where they may be forced 

 to flower in February and March, but they l)ecome exhausted by this 

 method, only to regain strength after two or three years. 



Propagation. Shrubb}"^ forms are propagated by grafting on the 

 largest rooted herbaceous kinds in August before the fall growth 

 begins; by division; by cuttings of the young shoots in spring, in a 

 little heat under glass; by layers and suckers. Herbaceous forms are 

 propagated by division of the roots in August or early spring. Seeds 

 of any variety sown in September, in a cold frame, will germinate, 

 some the first, and others the second s[)ring. The horticultural vari- 

 eties produced from seed are numbered by the hundreds and thousands, 

 each beino; wiven its trade name. These different forms retain their 

 characters when propagated asexually. Many of the new forms are 

 o))tained by crossing varieties, as those of allt'ilioi'ii^ and ojficinalis. 



The latest extended accounts of the genus were by J. F. Baker in 

 (iard. Chron. 21:732, 1884; and R. I. Lynch, in Journ. Royal Hort. 

 Soc. 12:42s. 1890.

Stem 3 to 6 feet or even higher if not cut back, much branched; 

 leaves glabrous: leaflets more often entire at tiie base of the plant than 

 above; flowers as in P. ojficrniiliK, but various in color: follicles num- 

 erous, very hairy, rather small. ALay-June, China. Long cultivated 

 there where varieties are numbered by the hundreds.
