Cult. The species of Pentstémon are amongst the most showy 
border flowers we possess in our gardens. ‘They grow best in 
light rich soil, and are readily increased by divisions and cut- 
tings. They are rather tender, being usually killed by severe 
frosts or damp in winter, if allowed to remain in the open air ; 
it is therefore safest to keep a few plants of each species in pots, 
so that they may be readily sheltered by placing them under a 
frame in winter.
