BLISS IN THE STREAM BED

As the seasons progress into winter, Ed and I are always delighted to see flowers in bloom. This week we were at 6000 feet in the Catalina mountains. It was a beautiful day and the temperature was very comfortable. We went to Chihuahua Pine picnic area, where the Mexican Jays (Aphelocoma ultramarina) were keeping their eyes on the picnic tables hoping for scraps of food.

We walked up the stream bed, through the tunnel under the highway, and further into the Hitchcock Campground area. On the way we saw a number of Goldenrod plants in bloom (possibly Solidago missouriensis).

In the dry stream bed most of the Hummingbird Trumpet flowers (Epilobium canum) were gone, but we recognized the plants, and did see some of their spectacular flowers.

We could smell the presence of Mountain Marigold (Tagetes lemmoni), with its yellow flowers and orange centers. Most of them had finished blooming, but the fragrance is in the leaves and we were aware of them as we walked past whole clumps of them.

Just under the tunnel we saw the familiar Alligator Juniper tree (Juniperus deppeana), in a very unfamiliar shape. Note how the trunk is mostly smooth, with a strip of bark running up the left side. We wondered how the horizontal ridges had formed. There were needles, so the tree was still alive in spite of having lost so much of its bark.

I continue to work on paintings for the upcoming show in March, 2018. This watercolor is  a view on a ridge looking North, with a circle of stones evidently used as a fire pit.

LATE BLOOMERS

We are getting toward the end of the year. Day-time temperatures in Tucson are still in the 80’s and 90’s. At our house we have had only a tenth of an inch of rain in the last ten weeks. We are still able to hike in the mountains. To our amazement we are still finding plants in bloom, even though at over 8000 feet the thermometer drops to near freezing at night.

Here are some of the plants we have seen:
Red Penstemon –  Penstemon barbatus (just one)

November Penstemon

Hooker Evening- Primrose – Oenothera elata var.hirsutissima (only one)

Evening primrose

Western Sneezeweed – Hymenoxys hoopesii (a few)
Sneezeweed
Wheeler Thistle – Cirsium wheeleri (several, in a much deeper purple color than we normally see in the Summer)
Thistle
Bitter Dock – Rumex obtusifolius (There is a lot of this non-native plant, but the flowers are so small that it takes work to find if it is actually in bloom)

Yellow Salsify – Tragopogon dubius (Just one – Even in mid-morning the flower had not fully opened)

In the colder weather I am taking fewer trips to the mountain. This has left me time to work on the book “Small Wonders” which is now in the hands of my editor. That is a big relief. It will have over 200 species in it. And now, with fewer hikes, and the manuscript of that book off my desk, I am devoting myself to painting. Here is one of them. These are being done for a show at the Contreras Gallery in Tucson in March 2018.

GALLS ETC.

As we wander the mountains north of Tucson we often come across unusual growths on plants, especially trees. At first glance they look like some kind of fruit. Since acorns are easy to recognize, the growths on different oak species clearly must be something else. It turns out that they are galls. These are formed by the tree in response to an irritation by an insect, mite or fungus. Here are three different oak species with their galls:

Silverleaf oak – (Quercus hypoleucoides) – This gall is a perfectly round sphere, about the size of a ping-pong ball. This is formed by a wasp that lands on a twig, irritates it in some way, and then deposits eggs in the growing gall. The eggs are well protected (and fed) as they develop. Once I cut a gall open. At first I thought there was nothing in it – just a little dark spot at the very center. Taking out my loupe I noticed that the black spot was actually a group of maybe a half dozen tiny little wasps. When the wasps hatch they eat their way out of the gall, leaving a perfectly round hole to show their exit.

Quercus hypoleucoidesGall2

Once I saw a very different collection of galls on the Mexican Blue Oak (Quercus oblongifolia). These were also little red spheres.

Quercus oblongifolia Galls

More recently we were hiking at about 8000′ with the Net Leaf Oaks (Quercus rugosa) which had galls, all on the underside of the leaves. Instead of a nice round gall, it is more like a very hairy red mass. We found that the mass consisted of a number of cylinders, each of which contained wasp larva.

SMALL WONDERS TALK
I have been working for several years on a book about the nearly invisible flowers that do not make it into most flower books. This coming Thursday, September 14, 2017, I will be giving a talk to the Tucson chapter of the Arizona Native Plant Society, 7 pm at the City of Tucson Ward 6 Office, 3202 East 1st Street. This is south of Speedway Boulevard and east of Country Club Road. I would love to see you there and share over 60 species worth a closer look. Here is one whose name, Eucrypta micrantha means “well hidden small flower”. The “well hidden” refers to the seeds. The common name is Dainty Desert Hideseed.

THE RAINS CAME

For the last week the Catalina Mountains have been closed to all but emergency vehicles as firefighters struggle with a fairly large fire. In the last 12 hours over an inch of rain fell on our property, and probably a lot more on the mountains, so the fire must be well under control. It has been just two months since we had rain. We have had to fill our bird-bath every day, which means that the hot sun has evaporated an inch of water in twenty-four hours. If you multiply that by the number of days, over five feet of water has evaporated since the tenth of May. It is a wonder that any vegetation has survived.

Here is a picture of the Brittlebushes in our back yard. It will not be long until they revive and turn green again.Brittlebush in back yard

 

In spite of two months without rain, the Desert Milkweed (Asclepias subulata) in the same back yard is in full and glorious bloom.

With the mountain closed, I have done a few watercolors. Here is one showing a view from Oracle Ridge,. The area caught in the sunlight is the Reef of Rocks.

Now that the summer rains have begun, we can expect a profusion of wildflowers in the mountains.

Art and Life

It is still cool in the mountains, though the valley temperatures are close to one hundred degrees. On a recent trip I started on a trail out of Marshall Gulch only to find the trail blocked by four fallen trees. This was a reminder to me of how much we owe to those who maintain trails. Without maintenance, most of the mountain trails would be impassable in a few years.

On a recent walk on Oracle Ridge in the Catalina Mountains, Ed and I were struck by the beauty of the Parry’s Agave, sending up sturdy flower stalks. We also noted something neither of us had seen before, the male flower cones of the Ponderosa pine opened to release pollen. We had seen them in their tightly closed form, with their beautiful scales. On this trip we saw how the cones expand to release pollen, seen as pale yellow dots on the picture.

My friends Hilary and Andrea took me to Oracle State Park. One of the nature trails afforded a view of the historic Kannally Ranch House in the distance. I took a photograph and later did this little watercolor of the view.

Speaking of watercolors, on Saturday, May 6, 2017, the Bear Canyon Library in Tucson will feature a show of three nature photographers, Brian Gersten, Tom Trebisky and Leslie Eguchi, plus six of my plant portraits, done in watercolor. This one is of the Canadian Violet (Viola canadensis). The opening reception is from 3 to 4:30, and you are all welcome.

SEEN ON NATURE WALKS

Recently our congregation in Tucson, Sunrise Chapel, celebrated the 30th anniversary of its building. All five of our children were here for the event, and even put together a musical combo – “the Band of Roses” – for our enjoyment.

Our oldest son had to leave early Monday, but the other four were able to join me in a walk in Catalina State Park. The flowers were magnificent, the buttermilk sky, amazing.

Catalina clouds

One of the group spotted this unusual saguaro. There are a number of crestate saguaros in Arizona, but this one was different. The crest was surrounded with arms, and protruding out of the crest were about a dozen new arms.

Ed and I were looking at plants in Saguaro National Park East, and saw a flash of yellow in the middle of a nearby shrub. We wondered what it was. “I think it is a yellow mustard”, I said. Ed reached in, and pulled it out. And this is what he had in his hand. It was clearly labeled: Heinz Yellow Mustard.

Every time we hike, we see new plants coming into full and glorious bloom.

SAGUAROS

It has been a quiet time for flowers. Today Ed and I walked in Saguaro National Park East. On the outward journey we did not see any flowers in bloom, so we paid attention to the many forms Saguaros take. Normally they have a single trunk, but we found one that had four.

Carnegia gigantea quadruple

We have had about three inches of rain since January 1 this year, and the Saguaros have expanded, in some cases to the breaking point. Here is one that is not only very fat with water, but has a long split. We suppose it just burst its skin there.

Carnegia gigantea split seam

Normally the ridges are vertical in saguaros, following the lines of the trunk and arms. For the first time we saw one with a different pattern on top of which is a new arm.

A little farther on an almost complete Saguaro Skeleton had fallen across the arroyo.

Saguaros need a nursery plant in their tender early years. Almost any fairly long-lived plant will do. We came across a fallen Palo Verde (or was it a Mesquite?) That had evidently given shelter to a whole ring of Saguaros. The nursery plant has fallen, and the family of Saguaros stands as if in respect.

On our return trip we found three species of plants in bloom: Desert Zinnia (Zinnia acerosa), Filaree (Erodium cicutarium), and Brittlebush (Encelia farinosa.)

Paved trail

We were particularly thrilled with the newly paved trail – the Mica View Trail. It goes seven tenths of a mile from the East end of Broadway to the Mica Picnic Area, and provides an opportunity for people in wheel chairs or baby strollers to easily explore the gorgeous Sonoran desert. Congratulations to those who made the desert accessible to more people.

FLOWERS IN DECEMBER

It is December 12 in sunny Arizona. We have had a number of days where we woke up to ice on our bird-bath. It is still cool at night, but today was sunny and pleasantly warm. Dave and I went to Molino Basin. We walked up the dry stream bed, only once coming across a little pool, left over from the rains just over two weeks ago. We looked for signs of aquatic life, but only found a few dead plants and insects in the water.
stream-bed The dry stream bed
Althogh we knew that we were in the middle of December, we looked out for wild-flowers, and found more than we expected.  Most abundant was the Hummingbird trumpet (Epilobium canum). Then we saw a few flowers of the Gumhead (Gymnosperma glutinosum) which we have seen blooming most months of the year, though its main season seems to be late fall. It was a great treat to see the blue flowers of Stemodia (Stemodia durantifolia). Then there were two more yellow composites: Little lemon head (Coreocarpus arizonicus), and, one of my favorites, Bur marigold (Bidens aurea).

We sat on the warm sand as time disappeared and we felt the healing power of being in the mountains again.

Life in the Desert

Since I have taken an interest in “invisible flowers” it made sense for me to go to go to a talk called: “Desert mistletoe: A misunderstood, but beneficial native plant” given by Kelsey Yule. This was presented to the Tucson Chapter of the Arizona Native Plant Society. The following Saturday Kelsey lead a walk to look at these fascinating plants. She talked about their life cycle, and how their sticky fruits are sometimes stuck on the branches of a desert tree, maybe by a bird. For a while we wondered where our leader had gone, and then she came back with a short stick of wood. On it there was a tiny lump. We had to get out our loupes to see what it was like. Fortunately my camera has good close-up power, so I was able to get a photograph. In it you see the grey lump of the seed, and a tiny red tube arching up and down into the branch. She explained that the tube was a haustorium, which is like a root, but is different enough to have its own name. She said it would take five years before the plant developed to the point where it could grow and produce flowers and fruit. She also explained that the fruit is edible, but so far I have not dared to taste one.

Our home was enlivened by the advent of granddaughter, Gillian, her husband Dave, and 3-year old Mae, and 9-month old Siena. As part of their time here we went to Agua Caliente Park in Tucson. The first thing that caught Dave’s eye was a thin snake curled up on the path, surrounding a little whitish ball of fur. It was eating a mouse, and we were able to watch until it was just a fat lump in its slim body. Later we went to the butterfly garden where the white milkweed flowers were being visited by about a dozen Queen butterflies. Mae was thrilled to touch one of them.

It is November, and there are not many flowers, but the Desert Mistletoe plants are full of fruit, much to the delight of birds and other animal life.

POND LIFE

Dave and I were exploring Bear Canyon in the Catalina Mountains. The stream was intermittent, with long stretches of dry sand, and occasional pools. When we got to the area pictured here, we sat down to relax and talk. The pool was about 10 by 20 feet, and a foot or two deep. We were on the north side of the water, so ripples in the surface sparkled in the sunlight.

bear-canyon-pond

Then we noticed what looked like a cluster of four stars moving erratically across the water. Looking through our binoculars we saw that each star was an indentation in the water caused by the legs of a water strider. We also noticed that the two front legs are very much smaller than the side ones, and created smaller stars, so there were six in all. (Gerridae are a family of insects in the order Hemiptera, commonly known as water striders, water bugs, pond skaters, water skippers, or jesus bugs. Wikipedia)

It was somewhat hypnotizing watching these insects dart around the pond. We imagined that this might be their whole world. In addition to skimming the top of the water, they occasionally jumped, doing so quickly enough for us to wonder where they had gone.

Then a white moth (or butterfly), landed on the pond, at first lying quite still. The water striders started to gather around, and looked as if they were going to feast on this delectable corpse, when, all of a sudden it started flapping its wings furiously. The encircling mob immediately retreated. We were fascinated by the sun reflecting off the ripples, and the shadows of the ripples making fast moving circular patterns on the bottom.

butterfly-skipper-ripples There seem to be about six striders in this view

After a few seconds of furious motion, the moth lay perfectly still. The striders cautiously started to move in, only to be panicked by another flurry of wing activity. We noticed that the beating wings did not leave the surface of the water. They were more like paddles on a row boat.

In addition to the striders a couple of dragon flies came into the area right above the water, darting back and forth and then disappearing upstream. We were amazed at how they managed to avoid a spider’s web that hung in the still air.

The drama with the striders and the dying moth continued, and we left the area long before it was finished. We felt privileged to share their world, if only briefly.

BOOK SIGNING
This coming Sunday, November 6, I will have a book signing at our church – Sunrise Chapel.
The chapel is on 8421 E. Wrightstown Road, between Pantano and Camino Seco, in Tucson. The signing will be on the Patio from 12:15 to 1 pm. I will have these three books: “Bo and the Fly-Away Kite (written by Virginia Ames and illustrated by me), “Church Growth Pains and Pleasures” and “More Wildflowers and Trees” containing photographs of 343 plants thast did not make it into my other books: “Mountain Wildflowers” and Mountain Trees” which will also be on sale. Notecards of my wildflower portraits will be available. I would love to see you there.
