Pentstemon is a term which we have previously 
had occasion to notice. Richardsonii, from the 
name of an English botanist. 
We are glad to introduce any additional species 
of this genus to our friends, convinced, as we are, 
that they will meet them with pleasure. Of about 
thirty species of Pentstemon, now cultivated in Eng- 
land, one half have been introduced since we com- 
menced the Botanic Garden ; so that, as regards this 
genus, more remains to be done than at the outset. 
The Pentstemon Richardsonii is a more durable 
plant than some of its congeners. Of the roseum, 
No. 316, and antropurpureum, No. 275, we have 
raised numerous seedlings; but many of them, ex- 
cepting by cuttings, did not continue more than three 
years. Perhaps it is not greatly to be regretted, 
that these attentions are required at the hand of the 
cultivator. Propagation for our own borders, and 
also for distribution to friends, constitutes one 
amongst the many enjoyments of a garden. 
The Pentstemon Richardsonii does not admit of 
division at the root. It should be increased by cut- 
tings, about Midsummer, which readily strike root.
