Arenga saceharifera, in a young state, is surpassed in 

 beauty by most palms. Specimens eight to ten years 

 old, however, show their characteristics well, and from 

 that period till they begin to flower (which they do from 

 the top of the stem downwards in the axils of the leaves ) , 

 they are among the most striking subjects for high and 

 roomy conservatories- The temperature should not be 

 allowed to fall below 55° F. during the coldest weather.
