Rock Garden Species 
of Penstemons 
The miniature Penstemons, both shrubby 
and herbaceous, have a charm and variety 
that is hardly duplicated in any other group 
of flowers. Many of these beautiful little 
plants, too, have not been available to the 
gardener before and we take pride in being 
the foremost introducer of this genus. 
The species considered here are the dwarfs, 
most of which have quite ornamental foliage 
and that make attractive clumps or’ mats. 
P. linarioides coloradoensis has _ silvery 
gray leaves that remain bright and fresh all 
summer and usually all winter, too. If 
planted in the rocky part of the garden the 
branches tumble over the rocks in a pleasing 
‘Manner, 
P. thompsonae, a Sedum-like shrublet with 
tiny gray spatulate leaves, almost white in 
appearance. It is not over 1 inch high and 
makes little mats to 6 inches across. The 
flowers are violet and produced on tiny erect 
spikelets. Hardy and stands the sun and 
drought (deserts of north central Nevada): 
P. acaulis is a challange to the good flow- 
er grower. Its requirements are for desert 
treatment. It resembles a tiny Phlox, with 
filiform leaves, growing in small clusters. 
The tuffets grow as much as 10 inches 
across but usually 2-4 inches. Its little blue 
flowers sit on top of the pan cake clumps of 
foliage; native of the foothills of the Uinta 
Mountain range of Utah. 
P. exilifolius has white erect flowers on 
slender airy spikes. It forms a neat light 
green mound with short grassy leaves very 
similiar to the cushion Dianthus. 
P. paysoniorum, a dwarf only 6 inches 
high and found in the dry sandy washes on 
the desert plains of Wyoming. The leaves 
are dark green, shiny and in rosettes close 
to the ground. It is floriferous; medium blue 
in color and small; found on desert plains 
of Wyoming. 
P. halli, another dwarf Glabri, with im- 
mense flowers in proportion to the size of 
the plant. It makes attractive rosettes of 
shiny dark green leaves above which forms 
erect 6 inch stems that are covered with its 
rich deep red purple flowers: Try it in a 
well drained place protected from the sun 
by a rock; found high on mountain peaks in 
the Colorado Mountains. 
P. virens, a beautiful and dainty plant 
that grows in cut banks and gravelly hill- 
sides. It makes a thick mound with bright 
green lanceolate leaves. The flowers are a 
cloud of blue, on stems 6-8 inches high, giv- 
ing the bloom an airy effect; the flowers are 
small but numerous. Found in Colorado 
and southwest Wyoming. 
P. Tolmiei is a charming plant, a mat 
former, the root stocks rooting as they ex- 
tend along the ground. The leaves are a 
deep green, lanceolate shaped and numerous: 
The flower stems are 8-12 inches high, topped 
with small, compact clusters of tiny red-purp- 
le flowers.; they are found in the Cascade 
mountains of Washington. 
P. heterophyllus, subspecies, purdyi, is a 
dwarf decumbent form and does well for cov- 
ering dry banks but it is tender in the north- 
ern section of the country. It makes a very 
attractive low mound with olive-green leaves 
with a touch of bronze, making it very orna- 
mental. The flowers are blue, purple or 
rose or in combinations of these, making the 
effect spectacular. ‘
