Recently I was exploring the area south of the Santa Rita mountains with my friend, Jim. We were particularly interested in grasses, but kept coming across other plants of interest, including this one with the yellow flowers (Melampodium). When I processed the picture I noticed what seemed to be a yellow flower right at the base of the stem. Then I zoomed in and found it was a spider! I believe it is a Goldenrod Crab Spider (Misumena vatia). Years ago I was processing a picture of a Bouvardia plant, and found one tucked in among the red tubular flowers. It seems that this particular spider does not make a web. Its color enables it to perch unseen on a yellow flower and just wait for insects to land on it. Maybe this one was trying out a red one to see if that would also do the trick. These spiders also come in white, and can change color to match the flowers they visit.




Recently my old friend, Virginia Ames, published her charming book: Bo and the Fly-Away Kite. She is old in two senses. I have known her for many years, first meting her in 1982 – 34 years ago. Now she is 102. And this is her first children’s book which I was honored to illustrate for her. She is an accomplished water-color artist herself, but chose to have me do the illustrations. It is unique in having the text in three languages, since the story includes three boys – English speaking, Spanish speaking, and O’odham speaking. Here is the link on


We have been going on plant walks every week since June, and every week we see fewer flower species in bloom than usual. The last rain here was April 11 – just under eleven weeks ago. What a thrill today when the heavens opened and almost an inch of rain was recorded in our rain gauge! In a few hours the temperature dropped thirty degrees.

There are some wildflowers in bloom, including three that I have never noticed before. One of them had been on Joan Tedford’s plant list for years, but I have never seen it. Perhaps this is because it has leaves that look very much like the walnut trees which grow in the same area (about 6000 feet in elevation.) When I saw the leaves I thought it was just another walnut tree, but then I looked at the flower cluster and knew that this was a plant I had never noticed in the mountains. I could have seen it in other places in America since apparently it is the only tree or shrub that can be found in all of the lower 48 States.  It is called Smooth Sumac (Rhus glabra).   I look forward to seeing the red berries, and its brilliant red leaves in the autumn.

Another new plant – not yet identified – looks like a lactuca, but it seems to be one that I have never seen before. The third new plant is a Galium. I am waiting to photograph it when it starts to bloom in a week or so.

I recently produced a new book of plant photographs. I call it – “More Wildflowers and Trees.” It includes photographs of plants that did not make it into my books: “Mountain Wildflowers of Southern Arizona” and “Mountain Trees of Southern Arizona”.
The new book has been printed in a very limited edition. Later I plan to print more. It contains photographs of 342 species.

On Father’s Day (June 19) the Arizona Daily Star had a two-page article titled “Art Strengthens Family Ties – Father, son share love for creating watercolors.” This excellent article was written by  Angela Pittenger and features our son, Owen, and me plus pictures of our paintings. I have had many very positive responses to the article.

We are all excited about the rain that fell today, and hope for more rain in the coming weeks. This should bring out many more of the wildflowers that I love so much.


Some time ago I heard from Jeannie at the Ranger’s Station that one of my favorite trees on the mountain had fallen. Early this month (May) we saw a front page article in the Arizona Daily Star: “100-foot tree towers no more in Catalinas”, by Doug Kreutz. Then I knew that it was time to go and see my old friend.  I have been hiking in the Catalina Mountains for thirty-four years and have come to know and love this very special tree. It was on a West-facing slope high in the mountain, and leaned over the trail. I have done a number of paintings of this magnificent specimen. This is one of them

I recalled my fear for the tree in the Aspen fire of 2003 when much of the town of Summerhaven and huge stretches of forest burned. When I finally got to visit the tree again, about a year after the fire I noticed it was in fine shape. I apologized to it for doubting its ability to deal with fire. In its two or three hundred year history it must have been scorched many times.

In the end it was not fire that brought the tree down, but internal decay. This made it vulnerable to the wind.

Soon after reading the article my wife and I went to hike at the top of the mountains so that I could see it for myself. Considering the angle of the tree I knew it must have completely blocked the trail when it fell. Sure enough I found the trail impassable, but people had made a route up the slope to the base of the stump and around the other side. I had a few moments of silent respect for the tree, and returned a little saddened by our loss

It was a Douglas Fir (Pseudotsuga menziesii). This is a species that is second only to the Redwoods in the height to which it can attain. Fortunately there are other giants in the Catalina Mountains, but none that I know of with this much character. We will no doubt see it lying across the trail for a long time to come, and will miss its majestic presence on the mountain.

On our walks lately we have seen plants in bloom but they are few and far between. We did see a Desert Spoon (Dasylirion wheeleri) with two flowering stalks. Normally they only have one that stays on the plant for more than a year. At least we think it was one plant. Sometimes plants grow so close together that their leaves become entwined to the point that it is hard to tell whether it is one or two.

The Teddy bear cholla (Cylindropuntia bigelovii) has some of the densest collection of spines of all the cactus species around here. Some birds build their nests right in the thick of them where they can feel really safe and secure. How they manage to fly in and out without impaling themselves is quite a mystery. Recently we came across a dead bird lying on one of their branches. We assumed that it had been flying in and out of the plant successfully until it finally got hooked. Of course it could have died in the air and simply fallen to this resting place.

My wife and I occasionally have a burst of energy to de-junk our house. Last week we tackled the shed throwing out many large plastic bags of trash. And then, to my amazement, I found two oil paintings that I had done years ago. They were tucked away in the back corner. The fact that I had not signed them proves that they have never been in a show. As it turns out our son, Owen, and I are having a joint show at the Contreras Gallery (110 E. 6th St., Tucson) the whole month of March. We will frame these two oil paintings and make them the center pieces of my part of the show. You are all invited to the opening of the show, 6-9 pm, Saturday March 5, 2016.

Steve and I were walking along Oracle Ridge. A fairly steady wind was whistling through the bare trunks of ponderosa pines which were burned in the fire twelve years ago. As we looked up we could see ravens circling around, playing with the wind and with each other. At first there were just a few. After a while I counted twenty-four, and knew there could have been more. When I finally woke up to the possibility that this would be worth photographing, one of the ravens had settled on the top of a burned out tree, and a few others were near. Soon the dance was over, and the sky empty. What a treat!

Ed and I were making our way up Turkey Run and stopped, as we always do, to see if the rare and beautiful Shooting star flowers were in bloom. I took out my binoculars and thought I saw one lone blossom up the hill and to the right. Ed looked and questioned my perception. He said it was just a patch of sunlight on a leaf. The hill is very steep and wet. I had to scramble up and see for myself. I got near enough to the clump of foliage on the right to know that Ed was correct. Then I looked left and saw more than twenty Shooting star plants, all of them in bud and three with open flowers.

Years ago when I first saw these plants I got some good photographs and was able to do watercolor portrait of a group of plants, and a close-up painting of a single flower.

We were taking a plant walk in Marshall Gulch. Anne called me to look at a cluster of Coral root orchids. There were four in a little group. I managed to get a picture of what I thought was one plant, but turned out to be two. This is possibly the most densely flowered of these orchids I


have ever seen.

Coming down the mountain I stopped to see if the rare and somewhat obscure Catalina beardtongue (Penstemon discolor) was in bloom. I found them where I had expected to see them, and noticed that a few of the plants in bloom. I had my close-up camera with me so could get a really nice picture of one of these beautiful flowers.

February 13th was a beautiful day on the mountains. Dave and I went looking for some Iris plants I saw last year to see if there might be signs of them this early. Nothing. But then, on the west end of the Butterfly trail, the delightful Red Fuzz Saxifrage plants (Saxifraga eriophora) were starting up. With their mixture of red and green leaves, red flower stalk, and white or pink flowers, they are quite a sight. Some years I have even seen them poking through the snow. I went there again today and caught a picture of a flower cluster, glistening from the recent rain. It was a cool day on the mountain (38 degrees), and the flowers looked like they were doing fine.

We also saw Periwinkle and  Dandelion at 8000 feet. The beautiful Valerian (used as a medicinal plant for sleep problems)  has buds and soon will be in bloom (Valeriana arizonica).

Jim and I were driving along on our way home from botanizing in the desert. Out of the clear blue sky I asked him to tell me about Tackstem (Calycoseris wrightii). He wondered why I asked the question, and I explained that my chief Botanical advisor on the Flower book, Joan,  had come to the conclusion that Tackstem does not occur on the Catalina mountains, and is fairly rare in this part of Arizona. If we see a white flower like this in the Catalina Mountains it is almost certainly Desert Chicory (Rafinesquia neomexicana). He agreed, and said that sometimes, depending on weather conditions, etc, Tackstem may be found along some road sides. The flowers of the two are nearly identical, but the Tackstem has little tack-shaped glands growing along the stem, and base of the flowers.

A few minutes later I noticed some white flowers out of the corner of my eye and I suggested we stop and have a look. When we got out of the car and walked back to the flowers, we found that they were Tackstems! This is the first time I had ever met and photographed the plant.

Every time we go out, we see more flowers in bloom. On a recent hike I counted over 60 different flowering species. What a treat.


It has been almost a month since my last posting. Not being able to include pictures has been a deterrent to making new entries. Our son, Owen, has solved the problem, for which I thank him.




This is one of Owen’s great photographs





In the last week or so we have had a lot of rain – about three inches in three days at our house. Considering that this area receives only a little over ten inches a year, that is a lot. And more is on the way. This leads us to expect a spectacular show of spring flowers.

Recently Ed and I were invited by our friends Doug and Arlene, to see the birds in the nature preserve known as Whitewater Draw in Sulphur Springs Valley, near the border with Mexico. The preserve is one of a number of locations for the Sandhill Crane. It has several very large ponds, full of all kinds of water fowl and other birds. Doug and Arlene, both keen birders, pointed out a number of them: Great Horned Owl, Shovelers, Pintails, Coots, Ruddy ducks, Green winged teal, to name but a few. We arrived late morning.  It was a beautiful overcast day, with grey clouds reflected in the water. This part of the valley is flat, and is ringed with mountains ranges. I thought, “This is a watercolor day.” When we got home I did a little sketch which I will later develop into a painting.

We saw only a few cranes in the morning, but were treated to a large flock of Snow geese, which circled, finally landing in the water only to take off later, circle, and then land again. It was a wonderful sight, especially when the sun caught their brilliant white color.

We went to the old mining town of Bisbee and returned after lunch. As soon as we got out of the car we could hear flocks of sandhill cranes, in raucous conversation. They came swooping in, some landing on the ground, others waterskiing up to the shore. Later more flocks arrived. Had we stayed until dark, we might have seen as many as ten thousand of them. What a treat! The flocks stay here until the middle or end of February when they will migrate north for the summer, some going as far as northern Canada and Alaska.

The June issue of TUCSON LIFESTYLE HOME & GARDEN has an article called: “Blood is thicker than watercolor” by Megan Guthrie. It is a fine write up of the father/son duo, Frank and Owen Rose. This is one of the paintings featured.

It has been a long time since we have had significant rain here in Southern Arizona, but there are many flowers in bloom in the mountains. There is a field of Lupine (Lupinus palmeri), the only Lupine species growing high in the mountain (4500 feet and above). The flowers are normally blue, but in one patch we saw three albinos.

Not far away was a rare example of Green gentian, or Deer’s ears blooming (Swertia radiata). These plants have large leaves, (like deer’s ears) and year after year store energy underground until they finally send up a flowering stalk. These can be as tall as eight feet.

Another large plant is Cow Parsnip (related to Hemlock), whose name Heracleum lanatum, means woolly Hercules, referring to the Greek muscle man. The leaves can be larger than dinner plates. The flowering heads have many groups of flowers, and each group has many flowers. These tend to be irregular, with larger petals at the edges of the inflorescence.

Ed and I were hiking along the Mint Spring trail. We came to the site of the old spring, now dried up. Looking up we saw a hillside that used to be covered with Ponderosa pine. As you can see in this photograph, they all burnt in the fire 11 years ago. On one slope I did not see any new trees. About a quarter of a mile north there were many young pines. But the most successful trees after a fire are the Quaking Aspen. These trees regenerate from the roots, and a patch that seems to contain hundreds of trees may be just have one root system underground with many trunks rising out of the ground as if they were separate trees.

These days the temperature goes above 100 degrees in the valley, but the mountains are cool and beautiful. And the plant life on the mountain is slowly coming back after the fire of 2003, a fascinating process to watch.


Last Wednesday Dave delivered my new computer. It has been over three weeks since I let go of the old one. Most of that time I have spent trying to get over a heavy cough and cold, which meant that I was not getting out into nature the way I love to do. Sorry about the long gap between postings.

At the end of January (Jan 29)  I reported finding a fungus (Puccinia monoica) that invaded a plant, Rock-cress (Boechera perennans), changed its growth pattern and made the leaves look like flowers. Yesterday Ed and I went to visit the infected plant to see how it was doing. Though it looks a little the worse for wear, you can see in the photograph that the growth pattern is still the same and the fungus is still turning the leaves on the tip of the plant yellow so that they look like flowers (on a plant that has pink and white flowers.) The other Rock-cress plants nearby have mostly  finished blooming and have gone to seed. This fungus has been at work pretending to be a yellow flower for at least ten weeks.

We drove up the mountain to Turkey Run. It is still very early in the season and there are not many plants in bloom. We did see a healthy crop of dandelion. Later we found the orange gooseberry in bloom (Ribes pinetorum). For several years I tried to photograph this plant, but was too late. Here it is, blooming in April. On the way down the mountain we found its cousin, Golden currant, (Ribes aureum) in full bloom.

One of my favorite flowers on the mountain is the Green gentian or Deer’s ears (Swertia radiata). It produces a crop of very large floppy leaves each year for many years. In its final year, the leaf pattern is different as it sends up a flowering stalk which can be as high as 8 feet (as in this photograph). The stalk has hundreds if not thousands of pale green flowers. After it produces fruit, the plant dies. This means that it is monocarpic, meaning that it only flowers once in its life.

We enjoyed seeing Arizona Valerian (Valeriana arizonica). This genus is known as a medicinal plant, acting as a sedative. These bloom early in the Spring where in some damp places high in the mountain they carpet the forest floor.

This week end (April 12 and 13), I am participating in the Tucson Open Studio tour. Our home will be open from 11 am to 5 pm on Saturday and Sunday. Come on over.  (9233 E Helen St.)


In just a week my son, Owen, and I will have an opening of our art show at the Contreras Gallery. The opening is Saturday, February 1st from 6 to 9 pm, 110 E. 6th St., Tucson. This will be my fifth show at this gallery. Each year I have had a theme. Last year it was “Rocks and Water”. This year it is that great inspiration, the Grand Canyon. Here are two of the paintings.

“Canyon Highlights” felt right almost the moment I put paint to paper. When I had finished blocking in the main forms I liked it a lot and was almost afraid to touch it again for fear of spoiling the effect. It wasn’t until I had finished all but three of the 24 paintings for the show that I returned to this one, and decided to take the risk of working on it more. In the end I was very happy with the result. Incidentally, during our Christmas vacation, I had used the drawing for this painting as an exercise in teaching some of my family members watercolor. There are now a half a dozen versions of this painting in various homes in our family. All the young artists did wonderful work.

The Drama of Evening

The other painting is a full sheet (22″x30″), called “The Drama of Evening”. I love the contrasts of sunshine and shadow in these sunset views. A scene like this can be very fleeting, lasting only a few minutes. The people in the painting help to convey something of the scale of the canyon. If you are in Tucson on the first Saturday of February I would love to show these two paintings and the other attempts to capture aspects of this natural wonder. The show will include two of my oil paintings, and 22 watercolors, plus works by Owen Rose.
