FORSYTHIA 



Leaf of Forivthia viri-

up(jn the orround. This ai)i)('ars in the (k'aU'rs' cata- 

 h)^i;ucs under whatsoever name their hmcy pr()ni[)ts, — 

 ForsytJiia suspcnsa, luirsytJiia sciboldi, 

 Forsythia fort unci. It is good opinion 

 that ForsytJiia suspcnsa should be re- 

 garded as the speciiic form and For- 

 sytJiia sciboldi and ForsytJiia fortunei 

 varieties. As the three stand side by 

 side in the Arnold Arboretum the dif- 

 ference seems to be mainly a matter of 

 foliage; in habit they are very much 

 alike. The leaves of the F. suspcnsa 

 group are both simple and trifoliate ; 

 those of F. viridissima are always sim- 

 ple. There is an intermediate form, — 

 probably a hybrid, which carries the 

 leaf of F. viridissima slightly modified and whose 

 branches have somewhat the grace of F. suspcnsa; 

 this is know^n as ForsytJiia intermedia. A third torm 

 is of recent introduction ; it comes from Albania, is 

 named ForsytJiia europcea and is distinguished by small, 

 ovate-lanceolate, quite entire leaves. 



As the flower buds are formed the 

 summer before, in order to get the best 

 results the bushes should be pruned 

 some little time after the tlowering 

 period. Then every new shoot will 

 be laden with llower buds which will 

 give an excellent account of tliem- 

 selves the following April. II the 

 plants are pruned in winter the llowering spray is 

 very largely removed.
