A large Fremont’s Cottonwood Offers shade and protection along the Pima Canyon Trail.
In the shade, a grapevine, offers a vain promise of grapes.
The cottonwood’s deep roots draw water from a mountain stream.
Native Americans in the Western United States and Mexico used parts of Frémont’s cottonwood variously for a medicine, in basket weaving, for tool making, and for musical instruments. The inner bark of Frémont’s cottonwood contains vitamin C and was chewed as an antiscorbutic – treatment for vitamin C deficiency. The bark and leaves could be used to make poultices to reduce inflammation or to treat wounds.
The Pima people of southern Arizona and northern Mexico lived along Sonoran Desert watercourses and used twigs from the tree in the fine and intricate baskets they wove. The Cahuilla people of southern California used the tree’s wood for tool making, the Pueblo peoples for drums, and the Lower Colorado River Quechan people in ritual cremations. The Hopi of Northeastern Arizona carve the root of the cottonwood to create kachina dolls.
Here are 8 flower bud growing from one cladode (pad). There is a 9th bud on a second cladode. What is interesting about these pads are the needle shadows. Although thin, each provides some protection from the sun.
Cactus Closeup
This delicate bud will develop into a flower and, then, into a cactus fruit (in spanish, tuna). The fruit retains those tiny spines, called glochids, which detach on the smallest contact. The pads are also covered with them.
Prickly pears are known for growing into thickets. The Cuban government created a “cactus curtain” of prickly pears around the Guantanamo naval base in the 1960’s, to prevent Cubans from escaping to refuge in the United States.
Cactus Flowers
Look closely at the anthers of these flowers. Each curls over when touched, depositing its pollen. The habit of prickly pears to grow together in thickets mean there are clusters of blossoms in springtime.
Greater Bee Fly is reputed to be a nectar thief, making a cut in flower base to siphon off nectar without fertilizing the flower. This behavior is not in evidence here as it approaches this Carolina spring beauty on a late April afternoon along the South Rim trail of Fillmore Glen State Park.
Instead, what we see is this fly using a long rigid proboscis, found in the front of the head, to probe and feed nectar from the flower base as would any other respectable bumblebee that is resembles and is commonly mistaken for.

Claytonia caroliniana, the Carolina Spring Beauty, is an herbaceous perennial in the family Montiaceae. It was formerly placed in family Portulacaceae. Its native range is eastern and central North America. It is most found in the New England area of the United States, but its habitat extends from Ontario and a northern limit in the Cape Anguille Mountains of Newfoundland and south to Alabama.
It grows approximately 6 inches tall in forests of the Appalachian Mountains and piedmont.Claytonia caroliniana is a flowering, woodland perennial herb. It grows from March though June and is one of the earliest spring ephemerals. The plant grows from spherical underground tubers in light humus. They sprout and bloom before the tree canopy develops. Once the area is shaded, the plants whither leaving only the tuberous roots underground.
The flowers consist of five pink and purple petals. Dark pink veins accent the petals and give them a striped appearance. The carpels are fused together. I have heard the flowers are white when first opened, have not experienced this myself. They grow on a stem 3 – 10 inches tall that bears a single pair of broad leaves. There are two green leaves that grow opposite each other on a node. The leaf has no teeth or lobes and a prominent central vein. They grow up to three inches long and 1/2 to 3/4 inches wide.
In the photograph, Carolina Spring Beauty flowers bracket the leaves just visible under leaf litter.
Edible
The plant is edible, but its usability is limited due to difficulty harvesting and the small quantities each plant produces. Its tuberous roots are edible and rich in starch and can be cooked or eaten raw. The leaves can be eaten as well. The tuberous roots are eaten by eastern chipmunks and white-footed mice.
History
The plant was named after John Clayton. Clayton was an early collector of plant specimens.

Bombylius major (commonly named the large bee-fly, the dark-edged bee-fly or the greater bee fly) is a parasitic bee mimic fly. Bombylius major is the most common type of fly within the Bombylius genus. The fly derives its name from its close resemblance to bumblebees and are often mistaken for them.
Bombylius major exhibits a unique flight behavior known as “yawing” and plays a role in general pollination, without preference of flower types. The fly does not bite, sting, or spread disease. However, the fly uses this mimicry of bumblebees to its own advantage, allowing close access to host solitary bee and wasp nests to deposit its eggs. After hatching, the larvae find their way into the nests to parasitically feed on the grubs.
Flight
It has been discovered that the fly is capable of a unique behavior, which was discovered with the use of a high speed camera. In this behavior, the flies are seen to rotate around a vertical axis as they fly (this action is known as “yawing”). However, it is still unknown what can cause this behavior to be triggered and what purpose it serves, but a proposed explanation includes mating habits. Here is an illustration of “Yaw” in the context of an airplane…substitute the fly body with head facing forward (to left).
The Bombylius major bee-fly is a common, generalist floral pollinator, meaning that it does not give preference to one flower over another, instead pollinating a wide variety of plant families and species. The fly uses its proboscis to carry and transfer the pollen. The species is a dominant pollinator within its community, sometimes even pollinating up to two thirds of the local flowers. In addition, Bombylius major will visit and pollinate plants that attract few other species. Some types of flowers, for example Pulmonaria officinalis, will be almost exclusively pollinated by Bombylius major, with other species contributing a negligible amount to that plants pollination. Some flower species, such as Delphinium tricorne, are even specifically adapted to the fly in terms of color, shape, and form. If given the choice, Bombylius major will have a consistency in plant choice.
Flower Attraction
Long distance floral attraction is governed by optical sense, with color being the most important factor. The flies are typically more attracted to blue and violet colors, and occasionally yellow, over orange and pink. However, short distance floral attraction is based on the fly’s olfactory sense.
Sunbathing Activity
The fly is mostly active during day hours when the weather conditions are warm and sunny. Bombylius major is attracted to sunnier places and is more likely to pollinate these areas, with a larger average of flower visits in areas of higher amounts of sunshine. The fly will hide in the trees during the night and usually dart away from a cast shadow and occasionally hide in clean washing brought in fresh from the washing line and fly out causing unsettled behavior in the discoverer.

Purple Trillium, a different species from the white, present different challenges. The purple blooms tend to dip down toward the ground. White flowers face upward toward the sky. My successful photographs of purple (Click me for another Purple Trillium posting) have the camera lower than the plant, say where there is a bank above the trail.
Shot from beneath, White Trillium project a hopeful air. Here is a comparison of the two species in the environmental and individual treatments.

My visit to Finger Rock Canyon of the Santa Catalina Mountains filled two mornings. On the first morning, the subject was the lower canyon as morning light filtered over the eastern ridge.
Early morning to the north / northwest looking over a 20-foot fallen Saguaro Cactus (Carnegiea gigantean), toward lower ridges of the Santa Catalina Mountains. The saguaro is among a stand of healthy fellows, some with new growth and flowers on the tips of arms and main columns. This giant must have grown over rock through 60 years. It was brought down when the roots weakened. Specimens that are more reliably rooted can live to 200 years.
A clump of brittlebush shrub (Encelia farinosa) grows from the same rock.
Pima Canyon is the next over, behind that near ridge which provides similar shade. Unlike Finger Rock Canyon, the Pima Canyon trail follows the western cliff and loses the shade much sooner. During our three-week trip, my wife, Pam, and I visited Pima in our first week.
These photos were taken between 6:20 and 7:00 am.
Along the trail I noticed a multitude of buds on the tip of selected saguaro arms. In a previous blog, there’s a photo of this same saguaro in the shade. The following series captures the one blossoming top just as the sun passes over the eastern, shadowing, ridge.
The same saguaro, two minutes later…….
Here is a portion of the saguaro forest, around 7 am with the lower canyon filled with light. There are a few foothill homes with west and southwest Tucson. The Tucson Mountains are in the distance.
These photographs are a continuation of blogs from two days’ exploration of Finger Rock Canyon of the Santa Catalina Mountains, southern Arizona. Here we explore the nature of the Saguaro blossom.
Saguaro flowers start as buds on the tip of the cactus body or arm. The specimen in the photograph below, growing in the yard of a foothills home on the border of federal land, is over 30 feet tall and, at the end of April 2011, buds are sprouting from every tip. Look closely for opening buds and full saguaro blossoms.
Flower buds grow only from some tips and around the center, along the sides, not from the point at the very end of the tip, from which the limb grows.
These buds first appeared mid-April and are here shown in the latter stages of maturity, prior to opening. Sometimes, the base of an arm weakens and the arm lowers close to the ground while remaining healthy. While descending the canyon I noticed this had happened to the arm of a particularly large specimen, an arm in full flower. This and the following photographs are from that arm.
I have read that each flower opens in the cool of the night and lasts only until the following afternoon. Here is a fully blossomed flower with a pair of opening buds.
And more, from a different view of the same arm.
A saguaro flower in full bloom, having opened the previous night. This flower will last a single day. It will wilt in the heat of a single afternoon and close. In this brief time, flying animals will pollinate it. You can see numerous honey bees on the flowers, in a previous blog, “Saguaro Flowers in Finger Rock Canyon.”
Our Winter Aconite started blooming around Valentines Day, February 14, 2023.
The following photograph is from the Apple IPhone 14 ProMax, raw format and perfected on the phone. The rest are from the Canon 5D Mark IV with the lens EF 100mm f/2.8 Macro USB.
As a spring ehemeral plant, its life cycle exploits the deciduous woodland canopy, flowering at the time of maximum sunlight reaching the forest floor, then completely dying back to its underground tuber after flowering.
All parts of the plant are poisonous when consumed by humans and other mammals because it contains cardiac glycosides.
The species name Eranthis hyemalis proclaims the early nature of its flowering both in the genus, “Eranthis” – “spring flower”, and species, “hyemalis” – winter flowering. The genus encompasses eight species, all early flowering winter aconite.
