(probably), and Cytisus Adami, which bears yellow, rose, and brick-red 

 coloured flowers on one and the same tree. 



The general conclusion arrived at by a study of bud variations is that 

 while in the majority of cases the actual and immediate cause cannot be 

 more than approximately surmised, yet they may become hereditary, 

 though in the majority of cases they seem only capable of being perpetuated 

 by means of vegetative propagation. Moreover, they may, and often 

 readily do, revert to the original character, so that it frequently happens 

 that green-leaved shoots are seen to occur on variegated shrubs. While 

 the colours of garden flowers which have originated as sports are very 

 capricious when seed is sown, as in sweet-peas, pansies, &c, yet, if they 

 can be propagated by cuttings, then they may — but not always — be 

 depended upon, as in chrysanthemums and roses
