The garden race of Pentstemons has been 
bred chiefly from P. Hartwegii, crossed with 
other kinds, and the varieties, though much 
varied in size and colour, have yet a general 
resemblance in their flowers to the plant just 
named. The genus, however, contains numer¬ 
ous species of quite a dissimilar char¬ 
acter, all beautiful in their way, and all 
hardy, or just verging upon hardiness, and 
probably failing, when they do fail, more from 
the dampness than the coldness of our climate. 
In a tolerably free, well-drained soil, not liable

to be water-logged, they will survive our milder 
winters, but they are fully deserving of the 
shelter accorded to half-hardy plants, and with 
this help the}'' may all be kept secure. Most of 
them are increased in summer readily by cut¬ 
tings, which, of course, is a necessary mode of 
propagating the garden varieties, equally 
applicable to such kinds as P. campanulatus ; 
while most of the sorts bear seed freely, 
from which the species themselves may be
