Varieties. The seedling or garden varieties of Pent- 
stemon have now attained a high degree of excellence, 
and, as they are so readily raised, other additions are 
annually made, which represent improvement in form, 
size, or colour-markings, the result of selection, which 
the florist or specialist is rigidly prosecuting. The 
garden varieties are principally the offspring of P. Coba 
and P. Hartwegi, though other species may also have 
had something to do with the origin. Subjoined is a 
selection from the best varieties in cultivation. Many of 
the old ones are now of sufficient merit to hold their own 
against new comers.
