PENSTEMON ANGUSTIFOLIUS The leaves are 
narrow, deeply channeled and glossed with a light 
coating of wax that sheds water, deflects. sunlight, 
and adds a finishing touch to an attractive blue- 
gray-green. Normally some loose basal rosettes of 
these pleasant leaves are evergreen. Typical blos- 
som color is a melting deep azure, with a harmon- 
izing thread of soft pink at the throat. 
Climactic performance, as pictured above, may 
presage death, but in lean soils and with drought 
retarding development, heavy blossoming may occur 
in the fourth and fifth, even the sixth year. Exhaus- 
tion is often a trick of heavy production and fate- 
ful weather rather than mere old age, and careful 
husbandry will aid. Maturing a single stalk of seed 
satisfies the urge to reproduce, and cutting back 
of other stems immediately after flowering encour- 
ages setting of new rosettes for another year.
