PHYTEtTMA (old Greek name, meaning simply "a

 plants are little known in this country, but the follow-

because the species are much confused amongst horti- 

 culturists. None of the species seem to be regularly in 

 the American trade. 



Phyteumas generally seed freely and may also be 

 prop, by division, which is best performed in spring 

 after growth begins. They thrive in ordinary garden
