Wildflower of the Week: Eastern Pasqueflower

Pasqueflower (or Cutleaf Anemone) 
Pulsatilla patens ssp. multifida

While Sprocket and I were out hiking Ouray’s Perimeter Trail last weekend, I noticed a wildflower. It was only the first weekend of April so I was totally surprised that there were already flowers popping up through the snow! As it turns out, when I did, muddy snowmelt areas are precisely where you’d expect to find the pasqueflower.

These flowers are such pale purple they’re almost white. Their little petals are really delicate and the stems are almost fuzzy. They’re scattered all over the hillside where I found them!

Just a few days later, I also found them on the Thunder Trails near Norwood! They were everywhere!

I have been meaning to learn more about native plants in the San Juans and the Colorado Plateau for YEARS. In order to help me learn, I’m shooting for a weekly plant of sorts like I used to do with the Cactus of The Week feature. Writing the Cactus of the Week really helped to me learn those cacti and I’m hoping for the same to happen here!

Cactus of the Week: Plains Prickly Pear

Plains Prickly Pear
Opuntia polyacantha

The “plains prickly pear” has approximately seven subspecies. These subspecies often form hybrids between one another and at least two are found in southeastern Utah so I will not attempt to differentiate which subspecies this is here. (If you’re interested in more information about Opuntia polyacantha subspecies, this is a great resource.) http://opuntiads.com/O/opuntia-n-z/opuntia-p-r/opuntia-polyacantha/

Cactus of the Week: Whipple Cholla

We’ve left Arizona and the Sonoran Desert but Cactus of the Week continues with cacti found on the Colorado Plateau!

Cylindropuntia whipplei

While hiking in the foothills of the La Sal Mountains, we spotted this example of Whipple cholla. This is considered the “prostrate” form of the species; the whipple cholla can also grow to be 12-24″ tall more like the buckhorn cholla of the Sonoran Desert. The whipple cholla is found at high elevations (3,000-8,000′).

 

Cacti of the Week: Nightblooming Cereus

Nightblooming cereus

Nightblooming cereus
Peniocereus greggii

Nightblooming cereus is also known as “Arizona queen of the night” and “Reina de la noche.”

I’ve only seen this cactus once but apparently this cactus likes to grow underneath ironwood, creosote, and other bushes making it’s few, thin, stems hard to spot.

Nightblooming cereus

Nightblooming cereus is most famous for its white, cream, or pinkish strongly scented flowers. The flowers bloom after dark sometime in June or July and wither by morning.

Cactus of the Week: Many-headed Barrel

Many-headded barrel
Echinocactus polycephalus

The Many-headded Barrel cactus grows in mounds of closely packed stems, these mounds can grow to reach 3′ across! Mostly this cactus grows in the Northwestern part of Arizona but it is also found in a small area near Yuma (which is where I found this along El Camino Del Diablo).

Cactus of the Week: Corkyseed Fishhook Pincusion

Corkyseed Fishhook Pincushion

Corkyseed Fishhook Pincushion
Mamillaria tetrancistra

These little cacti are adorable. They’ve got short white spines that make them look almost fuzzy with larger black spines in the middle of each areole. They can exist as a single stem or in groups of about 3-10 stems. Their flowers are pink and their fruits are bright red (and almost look like a chile).

See how tiny they are? (Look in the lower left corner for the Corkyseed.)

Cactus of the Week: Senita

Senita Cactus
Pachycereus schottii

I hadn’t seen a Senita in the wild until we got to Mexico. While driving through the desert, I kept wondering what was up with the “hairy Organ Pipes,” once I got out and took a look, I realized they were a totally different species.

The Senita is another tall cactus (like the Saguaro and the Organ Pipe), measuring between 10′-20′ tall. They grow in large clusters, up to 100 stems. Their stems are hexagonal and waxy looking with a heavier concentration of spines at the tops of the stems that give them that hairy or shaggy appearance. The spines at the top of the stems are also longer than those at the bottom.

Cactus Of The Week: Engelmann Hedgehog

Engelmann Hedgehog
Echinocereus engelmannii

Engelmann Hedgehog

The Engelmann Hedgehog has cylindrical stems that grow in bunches of 3-60 stems. Most of the ones I’ve seen look like the above with 5-10 stems. They have wavy ribs and varied colors to their spines making them look “shaggy.”
