| Elm tree. In Colorado Springs, these things propogate and grow like weeds.
Kingdom: Plantae | 
|
| Gambel Oak tree. Also called scrub oak.
This one was found on 6 July 2008 alongside Fountain Creek, just West of
Manitou Springs, CO.
The second picture was taken on 25 August 2010, and shows the seed pod produced by this Scrub oak. It was at the Bear Creek Nature Center.
Kingdom: Plantae |  
|
| Aspen trees, near Elevenmile Lake, on 29 September 2006.
These trees turn their leaves a bright yellow in late September or early October.
If there has been a drought, they will turn a dull yellow.
Kingdom: Plantae The species we have in Colorado is the Quaking (or Trembling) Aspen, Populus tremuloides. They are called that because the leaves move in even the slightest breeze. |  |
| Cottonwood tree. These trees can grow quite large. Typically,
they do best if near a source of water. This one is just West of Manitou Springs, CO
near Fountain Creek. Picture taken 6 July 2008.
The Cottonwood tree found in Colorado would be the Eastern Cottonwood, Populus deltoides, and sub-species Rio Grande Cottonwood (populus wislizeni). Cottonwood trees, like almost all living things, come in two genders: male and female. The second picture shows the flowers that bloom on the male cottonwood. This picture was taken on 5 May 2009, El Paso county, CO. The third picture shows the seed pods on the female cottonwood. These pods release the millions of white fluffy seeds that float all over your neighborhood.

| Poison Ivy. Found on 1 June 2010 at the Fountain Creek Nature Center.
Kingdom: Plantae | 
|
| Poison Ivy, same place as above,
maybe even the same plant, on 4 August 2011.
| 
|
| This is the Virginia Creeper. Grows along anything that will let it
climb. Grows small bunches of small berries. Also known as the American Ivy.
It looks similar to the Poison Ivy, but Poison Ivy typically has 3 leaves in a
cluster; this has 5 leaves. Also known as Woodbine.
Some people make tea from the leaves.
By mid September, the small berries are blue.

| This is the Colorado Thistle or Elk Thistle,
or more properly known as the Meadow Thistle.
This plant is native to Colorado.
The first picture was taken near Elevenmile Lake, Park County. It was at least 1 foot across,
pushing back the surrounding grass.
The second picture was taken on 31 August 2010, also near Elevenmile Lake.
Kingdom: Plantae |  
| |
| This was found on 18 August 2013, near the Glen Cove resort at the 11,400 foot
level of Pikes Peak. The Ranger that checks your brake temperature on your way down said
that it was a "Hanging Head Thistle". I have not been able to find it by that name.
| 
| |
| The Colorado State University has a web page for Colorado Thistles,
http://www.coopext.colostate.edu/jefferson/npm/npm_docs/2012_Native_thistles_of_Colorado.pdf
and it shows photos that seem to match these nicely. CSU calls these Elk or Meadow Thistles, Cirsium scariosum.
I took some photos on July 5, 2016, at the same area near Glen Cove on Pikes Peak. They are not growing
as tall as they were three years ago, but the CSU web site also says there is a lot of variation. It also says they
grow from 8400-10,400 ft., so that is reasonably close to the 11,400 ft. elevation of Glen Cove.

| This is a Juniper, and probably the Utah Junipter, Juniperus osteosperma.
It is native to western Colorado, and other western states. We bought this one at a nursery
in Colorado Springs.
Kingdom: Plantae | 
|
| Wild Blueberries, at the Bear Creek Nature Center, Colorado Springs on 25 August 2010.
Thry are ripe now, so the Black Bears will soon be feeding on them. The Nature Center employees
have already stopped putting up the bird feeders to avoid attracting bears to the buildings.
Kingdom: Plantae | 
|
| This is a vine in the Bindweed family, Convolvulaceae.
It is the Convolvulus arvensis. It is also known as a Morning glory.
The leaves are shaped like arrow heads. This picture was taken on 17 June 2010
at the Fountain Creek Nature center, Fountain, Colorado.
Kingdom: Plantae |

|
| This the Common Milkweed, AKA Butterfly flower, Silkweed, Silky Swallow-wort, Virginia Silkweed.
The milky latex in this plant is toxic to many other wildlife species, but not the larvae and adult Monarch
Butterfly, which uses this plant as a primary food source. Two other insects that feed on this plant
without harm are the Red Milkweed beetle, and the Milkweed bug.
This picture was taken at the Fountain, CO Nature

| Cactus, in the EagleCrest sub-division north-west of Cripple Creek, Teller county, Colorado. This is about 3 inches across. |  |
| More pictures of the same species of cactus, in the EagleCrest sub-division.
These cactii were about 2" in diameter. I would estimate that there are more than 100 of them
just in my 2 acres of land.
These are known as the Simpson's Pincusion Cactus, and also the Mountain Ball Cactus. It is a high altitude cactus, and is quite common in Colorado. The identification (in September 2016) is from Roelof Salters, a cactus hobbyist in The Netherlands, but a frequent visitor to the places where cactus grow in the US.

Alyssa Erickson took this picture in June 2009 on a hiking trail
near Colorado Springs.
This is either the Colorado state flower (Aquilegia caerules)
or a closely related species. Most pictures of the Columbine show more purple
than I see in this one, but it may be normal variation.
There are about 60 - 70 species within the Columbine Genus.
Kingdom: Plantae |

| Myrtle Spurge (Euphorbia myrsinites).
These pictures taken in El Paso County, Colorado.
Blooms early, this picture taken on 16 March 2009, and it had
started blooming a week earlier.
The boards on the fence are 6" wide, so you can see how big the blooms are.
According to Wikipedia, although it is sometimes grown as a decorative plant in gardens, particularly valued in xeriscaping in dry areas, myrtle spurge is often considered noxious, and is invasive in some regions. Its cultivation is illegal in the state of Colorado. The milky sap can cause significant skin and eye irritations.
Kingdom: Plantae | 
|
| A closely related plant is the Leafy Spurge (Euphorbia esula).
It is also known as the Green Spurge. It is in the
same genus as the Myrtle Spurge, above.
This picture was taken in Elbert Co., Colorado on 20 May 2009.
This plant is native to Europe, but has been introduced in North America. It is very invasive, and very hard to get rid of once it starts. Cattle will not graze on it.
Genus: Euphorbia |
|
| Yucca. The ends of the leaves have very sharp barbs.
If your finger gets stuck, it will hurt, but what is different about the Yucca
plant is that it will keep on hurting for several months.
There are many species, but judging by the looks of the seed pods in the second photo, this must be the Baccata species. These pictures taken 19 April 2008 in Elbert Co., CO.

|
| Wisteria. Takes several years before it blooms. |  |
| French Hollyhock, Malva Sylvestris. This blooms in late summer. It is a biennial, so we have to plant the seeds one year to get flowers the next year. Sometimes sold as "althaea", supposedly a perennial. |  |
| This picture of an Iris took 2nd place in the El Paso County, CO fair,
amateur photography competition, in
July 2007.
Kingdom: Plantae There are between 200 and 300 species of Iris. |

Cranberry Viburnum,
European Snowball Bush, Guelder Rose 'Roseum', and Viburnum opulus.
Kingdom: Plantae |   |
| Rhubarb. This plant was growing in our back yard when we
bought our house in 1976. It has been moved twice. This picture was taken
in 2003, which was a good year for it's growth. It is still here in 2008. My mother used to make pie, with 1/2 Rhubarb, chopped into small pieces, and 1/2 strawberries. When the stem part of the leaf turns red in the fall, it is ripe, and can be eaten raw. The taste is a little strong, however.

| This was found in Elbert County,
Colorado on 20 May 2009. It is a paintbrush
flower, in the Genus Castilleja. There are about 200 species in this genus, but this
is probably one of the Indian Paintbrush, and might even be Wyoming's state flower
which is the Narrow-leafed Indian Paintbrush, Castilleja linariifolia.
On the other hand, it also looks like the Castilleja miniata, Greater red Indian paintbrush,
which is supposed to be common in the Rocky Mountain area.
The second picture, taken in Park County Colorado on 31 August 2010, near Elevenmile Lake, looks like the same plant.

It looks quite a bit like the Moss Campion, Silene acaulis. That flower has pinkish-purple flowers, rarely white, and grows mainly above timberline. (These were found at about 9,000 feet, not above timberline, but definitely high altitude.) It also looks quite a bit like some species of Locoweed, Oxytropis. The leaf structure may also be more similar to the Locoweed. |
