This is the final post covering my Penstemon shots from 2010-2012.  Shown here are the 5 red or pink -flowering species of Penstemon I photographed across these 3 seasons.  1 of these species I had not photographed before–utahensis.

The 5 species shown in this post are:

rostriflorus
palmeri
eatonii
confusus
utahensis

early July 2010, Penstemon rostriflorus (b), S Mineral Mtns, Beaver Co, UT

early July 2010, Penstemon rostriflorus (b), S Mineral Mtns, Beaver Co, UT

When this species occurs in full sun, as shown, it can bear more flowers than when in shadier spots.

*

early Oct 2012, Penstemon rostriflorus, W Antelope Range, Iron Co, UT

early Oct 2012, Penstemon rostriflorus, W Antelope Range, Iron Co, UT

Plants that would flower during a year of average precipitation sometimes endure a dry springtime with essentially no precipitation, and then that summer they do not bother to flower at all.

*

early Oct 2012, Penstemon rostriflorus, central Antelope Range, Iron Co, UT

early Oct 2012, Penstemon rostriflorus, central Antelope Range, Iron Co, UT

The flower stalks you see on this old plant are all left over from the previous year.  In 2012 this plant did not flower.

*

early Oct 2012, Penstemon rostriflorus, E Antelope Range, Iron Co, UT

early Oct 2012, Penstemon rostriflorus, E Antelope Range, Iron Co, UT

However, in a different part of this mountain range I found a few plants with these very late-season flowers.  I believe these P. rostriflorus did not begin to flower in ~July like usual, but instead began in late September.  Here in this spot, mostly shaded by junipers and aided by the little rain that fell July-Sept, these plants released a few very late flowers–which came so late they probably failed to result in viable seed?

*

early July 2010, Penstemon palmeri, S Mineral Mtns, Beaver Co, UT

early July 2010, Penstemon palmeri, S Mineral Mtns, Beaver Co, UT

This species is very easy to see and has been transferred north of its native range during recent decades by humans.  Why did it fail to migrate into north half of Utah on its own, since now it persists just fine in patches there? Maybe on its own it had been progressing north slowly? Hmm.  In any case these plants here in the southern Mineral Mtns occur within the species’ natural range, I believe.

P. palmeri may be the only Utah-native Penstemon that has a good, strong scent.  I think this suggests it has evolved toward pollination by moths–in addition to the daytime pollinators it attracts.

mid June 2010, Penstemon eatonii, E Pine Valley Mtns, Washington Co, UT

mid June 2010, Penstemon eatonii, E Pine Valley Mtns, Washington Co, UT

Here along the Pine Valley Mtns, this species’ leaves are broad & irregularly ruffled.  Years prior, I had noticed these leaves looked much different than the P. eatonii leaves farther N and NE.  Before seeing these plants’ flowers, I assumed these plants must be something other than P. eatonii, and I mistakenly considered these plants P. laevis, which seemed reasonable based on what I could observe.  But no–once I saw these flowers it was obvious these are P. eatonii.

Penstemon pachyphyllus w P. eatonii (b), Confusions

early Sept 2012, Penstemon pachyphyllus with Penstemon eatonii, closer (b), Confusion Range, Millard Co, UT

I posted this shot in an earlier post that focussed on P. pachyphyllus.  Here the two Penstemon species grow near each other in the dry wash.

mid May 2010, Penstemon confusus, S North House Range, Millard Co, UT

mid May 2010, Penstemon confusus, S North House Range, Millard Co, UT

These two shots’ P. confusus plants were each growing in full sun.  This species can also occur in areas mostly shaded by pinion-juniper.  It seems to me that growing in full sun means, in most years, conditions will be too dry for P. confusus to flower.  But on a rare wet year these that grow in full sun might flower more than those in shade can ever flower.  That’s my theory.

*

mid June 2010, Penstemon confusus, W foothills, Hurricane Cliffs, Iron Co, UT

mid June 2010, Penstemon confusus, W foothills, Hurricane Cliffs, Iron Co, UT

Looks like this species likes red sand as substrate, too.

mid June 2010, Penstemon confusus, white-throated variant, W foothills, Hurricane Cliffs, Iron Co, UT

Notice the longer, pointier petals, and the white throats of this plant’s flowers.  This was the only odd variant I saw among dozens here of the usual ones.

These growing in the Confusions have flowers with bolder guidelines than those of this species I’ve seen elsewhere.

Late May on an average year is past peak bloom for this population here.  But I took some shots since I’d never photoed this species before.

Okay, take a look at this shot.  What is odd about it? Something is special.  See it?

Count the petals.  Penstemon flowers are supposed to have two on the top and three on the bottom.  I photoed my first six-petaled Penstemon flower here.  As a child I used to look at clover plants in search of a four-leaved clover I never found.  But I can say I’ve found a six-petaled Penstemon, woo-hoo.

Maybe six petals is fairly common in this population?

Shown here are 3 of the species of Penstemon I photographed across these 3 seasons.  1 of these species I had not photographed before–linarioides.

I’ve separated my flowering Penstemon shots from 2010-2012 into 3 posts.  This post covers bluish-flowered and short-stemmed species.  At least they are shorter than the 8 species in the preceding post.

The 3 species shown in this post are:

linarioides
dolius
humilis

mid June 2010, Penstemon linarioides, N of Central (a), Pine Valley Mtns area, Washington Co, UT

mid June 2010, Penstemon linarioides, N of Central (a), Pine Valley Mtns area, Washington Co, UT

It was a treat here to encounter this species new for me.  Flowering nearby were Eriogonum caespitosum–which was also a new species for me to photograph.

This shows the habitat of P. linarioides.  At a spot near here I noticed 5 species of Penstemon growing within 10m of each other–linarioides, humilis, rostriflorus, confusus & palmeri.

mid June 2011, Penstemon dolius, N of Drum Mtns (a), Juab Co, UT

mid June 2011, Penstemon dolius, N of Drum Mtns (a), Juab Co, UT

In 2011 Utah had above-average winter & spring precipitation.  That resulted in the flowers on these P. dolius.  It took me awhile to identify these, since the leaf shape tended a bit different than the only other P. dolius I’d ever seen–in a different valley NW of these.  It also threw me off that these grew in a county where the species had not been documented before.  But I think the leaf appearance is within that of P. dolius, and the flowers surely look like P. dolius.  So I conclude these are P. dolius, and this population would constitute a county record if I had been able to collect and submit to an herbarium a voucher.  Later I obtained a museum-voucher collection permit from the BLM, but in June 2012 when I returned to this area I found no flowers at all on these plants–as a result of the poor 2012 precipitation.  So this county-record population remains undocumented, as far as I know.

See the nondescript dry valley habitat of P. dolius…during a wetter-than-average year.

The remainder of this post covers P. humilis.

For quite awhile I could not confidently distinguish P. humilis from P. leonardii var. leonardii.  But now I think I can be clear about that distinction, and it turns out I’ve stumbled onto & photographed P. humilis in many places.

P. humilis is comfortable in part-shade.  However, it can occur in full sun.

mid April 2010, Penstemon humilis, Manning Cyn area, SE Oquirrh Mtns, Utah Co, UT

mid April 2010, Penstemon humilis, Manning Cyn area, SE Oquirrh Mtns, Utah Co, UT

Following this photo, snow would have covered this plant several times before winter completely ended.  Yet, here in mid April it is in the process of adding new growth in its tight rosettes of leaves.

early June 2010, Penstemon humilis, SW Stansbury Mtns (a), Tooele Co, UT

early June 2010, Penstemon humilis, SW Stansbury Mtns (a), Tooele Co, UT

This P. humilis plant was unusual.  It was growing in full sun and was the tallest and broadest plant with the most flowers of any P. humilis I’ve seen.  Here in low light near dusk, my camera accentuates blue tint.

In this hollow’s pinion-juniper shade, most P. humilis plants with this many basal leaves had sent up stems with a few flowers earlier this year.  But this plant had not.

This P. humilis grows at the highest elevation I’ve found the species.  I need to check, but I know this plant’s higher than 9,000 ft.  Maybe some July I should return to view this plant’s flowers & verify they appear to be classic P. humilis flowers.

mid June 2012, Penstemon humilis, Mercur Cyn area, W Oquirrh Mtns, Tooele Co, UT

mid June 2012, Penstemon humilis, Mercur Cyn area, W Oquirrh Mtns, Tooele Co, UT

The tan seed bracts and flower stems here are leftovers from the previous year.  See the absence of green ones.  In 2012 this patch of plants produced no flowers (& therefore no seed), due to very low precipitation in early 2012.  Elevation here is around 6,100 ft.

After months of below-average precipitation, plants at higher elevation are more likely to flower than lower-elevation plants of the same species.  Higher elevations receive more precipitation and dry out less.

Shown here are 7 of the species of Penstemon I photographed across these 3 years.  6 of these taxa I had not photographed before.

I decided to separate my flowering Penstemon shots from 2010-2012 into 3 posts.  This post’s species are bluish-flowered and tall.  The next post’s will be bluish-flowered and short.  And then the following post will cover red and pink -flowered species.

The 7 taxa shown in this post are:

sepalulus
rydbergii
watsonii
cyananthus
longiflorus
comarrhenus
cyanocaulis

*

late July 2011, Penstemon sepalulus (a), Wasatch Mtns, Utah Co, UT

late July 2011, Penstemon sepalulus (a), Wasatch Mtns, Utah Co, UT

I knew what these were when I first saw them growing here.  I’d seen nonflowering P. sepalulus once before, a bit farther N in Utah Co.  This species is like a southern version of P. platyphyllus, with narrower leaves & similar flowers.

This is my only photo so far of P. rydbergii.  Mid July is the end of this species’ usual flowering period.  Maybe I’ll photo one in mid-bloom stage, someday.  This species grows in grassier areas than the other Penstemon species I’ve shown.

early Aug 2010, Penstemon watsonii (a), South Snake Range, White Pine Co, NV

In western UT & E NV, if you walk up some range’s slopes & search in sun-dried areas near sagebrush, you can find some P. watsonii such as this.

mid Aug 2010, Penstemon cyananthus, Wasatch Mtns, Salt Lake Co, UT

mid Aug 2010, Penstemon cyananthus, Wasatch Mtns, Salt Lake Co, UT

When I took this shot I was not sure what species I was looking at.  I thought it might be P. leonardi var. leonardii, since I thought it was at elevation too high for P. cyananthus.  Plus this plant’s leaves look narrow for cyananthus.  But the flower looks cyananthus, and certainly is not leonardii since leonardii has black anthers rather than the tan/white anthers of cyananthus here.  Now I have realized P. cyananthus can tend to have narrower leaves when it grows at higher elevation.  Notice the Monardella glauca flowering in the background…a sign of the high elevation here, which is around 9,500 ft.

*

early July 2011, Penstemon cyananthus (a), W Oquirrh Mtns, Tooele Co, UT

early July 2011, Penstemon cyananthus (a), W Oquirrh Mtns, Tooele Co, UT

There’s some P. cyananthus in the Oquirrh Mtns, just like there’s plenty of it in the Wasatch on the other side of the Salt Lake Valley.

early July 2010, Penstemon longiflorus (a), S Mineral Mtns, Beaver Co, UT

This species, P. longiflorus, is a southern version of P. cyananthus.  To me, longiflorus is probably not different enough to be considered a separate species.  What do you think?

early July 2010, Penstemon comarrhenus (a), S Mineral Mtns, Beaver Co, UT

When I stumbled onto my first patch of this species new to me, I did not know what I was looking at & figured it out later.  It grows amid taller plant neighbors than other Penstemons.

*

early July 2010, Penstemon comarrhenus (d), S Mineral Mtns, Beaver Co, UT

early July 2010, Penstemon comarrhenus (d), S Mineral Mtns, Beaver Co, UT

This species’ name could reference whales, couldn’t it? Instead, “comarrhenus” refers to the unusual white hairiness on the anthers.  This can be seen on my first two shots, above here.

late May 2010, Penstemon cyanocaulis (a), W foothills of La Sal Mtns, San Juan Co, UT

This species was new to me when I took these shots.  Notice the (out-of-focus) wavy edges on the basal leaves in the shot below.  That’s uncommon for Penstemons, and was important to my identification of this species.

late May 2010, Penstemon cyanocaulis (d), W foothills of La Sal Mtns, San Juan Co, UT

Luck was not with me, as I was trying to photo this P. cyanocaulis.  They were at a great stage for catching their flowers, but the sunlight was very bright so that my shots were either too bright or too shaded.  Maybe I’ll be back in that area again someday when the light is better?

Watch for more bluish-flowered Penstemons in the next post.
