Plant Identification Questions and Answers / Nice (nameless) plant!
« Last post by JohnnyD on August 09, 2022, 02:50:03 PM »
I assume this 10-12 inch tall plant is a Penstemon but have no specific name. Help please!

After spending a considerable amount of time surveying the meadow, I moved on to higher and drier terrain. Sidalcea glaucescens is a common species found in dry open forest habitats. Their pink flowers are very showy.



Doellingeria breweri is another commonly seen species in dry open forests. This species has recently undergone a number of name changes. Previously it was known as Eucephalis breweri and now Doellingeria. The rayless yellow flowers of this species are quite showy.



Lupinus lepidus var. sellulus forms tight buns topped by lavender-blue flowers. This species is generally found in dry meadows.



Hidden away in higher terrain is Paradise Meadow. This site has no official name, but I like to call this site Paradise Meadow. I have been visiting this meadow for over 50 years. This meadow habitat is very stable and has changed very little in the last 50 years. The presence of Bluegrass, Poa pratensis, and Sheep Sorrel, Rumex acetosella, are signs that livestock grazing occurred in this meadow sometime in the past, however I never remember seeing recent signs of livestock grazing in this meadow in the last 50 years. This meadow complex contains plant species not commonly seen in the other neighboring meadows that received much more recent, frequent and intense grazing pressure for many decades.



I encountered a number of Viola species on this outing. Viola macloskeyi was the only Viola species that I found in bloom. Most of our Sierra Nevada Viola species bloom much earlier in the season. Viola macloskeyi is a widespread species found throughout much of Northern North America.

More photographs to come.

I am quite fond of white flowering plants in our Sacramento, California garden. At dusk when there is a full moon white flowers appear to glow in the twilight. In addition, many white flowering species are fragrant. It can be a very captivating experience. For me, your preference for the white flowering form of Fireweed is very understandable.

Our native Monkshood, Aconitum columbianum ssp. viviparum, is generally encountered near small streams, and seeps.



In our region we generally find the subspecies viviparum. This subspecies is easily identified by the bulbils that form in the leaf and inflorescence axils.



The riparian habitats in this area contain many interesting plant species, however I wanted to explore the neighboring meadows and drier habitats.

In this area, Symphyotrichum spathulatum is a good indicator of a mesic habitat. Even when conditions appear dry on the surface of the ground, moist soil is generally near the surface.



Ragged Daisy, Eurybia intefrifolia, is one of my favorite daisy-like plants in the Sierra and Nevada Mountains. The flowers and foliage is quite coarse, however I like its rugged disposition. This species is generally found in seasonally moist areas that can become very dry by the end of the summer. I frequently see this species growing with Penstemon rydbergii ssp. oerocharis, another lovely meadow species.



Diplacus torreyi is a dryland annual. Large colonies of this tiny annual can be very striking when seen in full bloom, however they are usually seen in scattered populations.

Lovely to see a picture of Chaemerion angustifolium - the common name in the UK is 'rosebay willowherb' - which remains one of my favourite wildflowers, despite being so common - it looks so glorious en masse. I grow the white form in my garden and although the developing seedpods don't echo the flower colour as they do in the wild version it has its own more elegant appeal - I fell for it when I saw the white flowers at dusk in someone else's garden - stunning.

Excellent, thanks very much for that! I was leaning towards that sort of idea but very good to have it confirmed by someone who’s had a bit of success!

Later in the summer the lavender-blue daisy Symphyotrichum spathulatum var. spathulatum is found blooming in moist meadows and forest openings. The tattered leaves of Veratrum californicum var. californicum can be seen to the left. This is the usual appearance of Veratrum leaves in the late summer and early autumn before the plants go dormant. This time of the year intact leaves would not look right. Maybe this is something to consider in a naturalistic garden environment?



Cirsium andersonii is found in dry sites in forest openings. Many of our California native thistles are quite attractive.



Erythranthe tilingii enjoys moist to swampy sites. This stand was quite robust and attractive.



The Alpine Lily, Lilium parvum, has small out-facing orange flowers. I have found specimens in the wild with over 100 flowers per stem as well as forms with up-facing flowers. In addition, there are golden yellow forms as well as lavender-pink forms of this attractive species.



There are many meadows in the area I visited on this outing. Many of the meadows have been severely degraded by livestock grazing and other human activities that started in the 1870’s and have continued, in one form or another, to the present time. Many of the meadows are in a state of flux. Lodgepole Pine, Pinus contorta ssp. murrayana, is encroaching into some meadows. Severely incised watercourses through many meadows have vastly altered the meadow hydrology. Introduced invasive plant species have also altered meadow ecology.

In this part of the Sierra and Nevada Mountains Helenium bigelovii is frequently found in moist meadows between 5,500 feet and 7,000 feet elevation (1,676 meters and 2134 meters).



Catilleja miniata ssp. miniata is most commonly seen in its orange-red flowering form. Golden yellow and yellow flowering forms are seen occasionally.



Here the orange-red form of Castilleja miniata ssp. miniata is looking good growing with Anaphalis margaritacea.



Here is a close up view of Castilleja miniata ssp. miniata.



Senecio triangularis is frequently seen in moist semi-shaded locations.

Thanks John. 
Here they seem to self without help, or perhaps crossed by random insects.  Flowering is over now but seeds are developing.
I usually send them to the SABG but this may be the last year :(

Very nice John.  First flowering is always exciting after a long wait :)
The foliage is attractive too, and in due course you may have a seed crop.

Ashley - I'll go to the ghouse right now and self it.  Just drop me a line and I'll send you some.  johnw
