Native Datura (Jimson Weed) Pretty with a Punch!

The first day we moved into our new house in N. Phoenix, AZ, we noticed a plant on the side of our yard that had dark, rather large, green leaves with tubular white flowers; also large. We had no idea what this was, but it was an impressive looking plant.

I have certain criteria for growing plants and one of them is the size of the flower in relationship to the size of the plant and leaves. I want a plant to offer color or a unique presentation. There are times when a plant provides other reasons for cultivation such as unique form, colorful leaves, etc., but I digress.

After doing a bit of research we found out that this plant was a native Datura or Jimson Weed.

Datura (Jimson Weed)

The plant pictured above isn’t the original plant, but it is a native Datura we grew from seed. As you will note it is rather large.

Here is a picture of a couple of the flowers in bloom.

Datura (Jimson Weed)

The flowers open in the evening because their natural pollinator is a Hawk moth which is out and about during the late afternoon and evening hours.

A close up of a single flower shows how inviting this might be for a moth or other pollinators such as bees. Every morning there are bees visiting the flowers to gather whatever pollen they can. The Hawk moth prefers the nectar and it has been noted by others that some of the moths seem to be a bit “high” as the Datura has hallucinogenic properties. Read more about that HERE.

Datura (Jimson Weed)

While this particular specimen is very white, I have seen others that have purple-to-pink tinges and, if my memory serves me correctly, I think one had purple stripes in the throat.

One of the positive characteristics of this plant from a gardeners point of view is that the mammals living in our yard, i.e. rabbits, squirrels, mice, packrats, javelina, etc. tend to leave it alone.

One of my favorite forms of the flower, because of its beautiful and unique form, is the swirled bud shape that it assumes the day before it opens.

Datura (Jimson Weed)

This particular plant wasn’t this robust its first year, but with every subsequent year, it has gotten larger and larger. The seed of this plant was harvested from a sprawlingly huge specimen. Now that it seems to have taken hold, we anticipate that it will remain a sturdy perennial.

This spring, once the blooms began to mature, I have been greeted with a dozen or more flowers nearly every morning. The flowers only last a few hours after daybreak and with the heat of the Arizona desert sun, this bloom interval will shorten.

I remove the spent blooms each morning and create a “dead head” bouquet.

This seems to extend the bloom time by preventing the formation of the prickly seed pods.

If you live in an arid area with the appropriate temperature range and you would like to grow an interesting plant that is mostly pest free, I think the Datura would be a good candidate.

Streets of Gold in the Phoenix Desert (Gardening)

Palo Verde Tree in flower

As you can see from the photograph above, the desert is decked in gold this time of year. The Palo Verdes (along with some other flowering trees snd shrubs) produce an abundance of yellow blooms. There are streets that are lined with these trees and they build a seasonal hallway of gold.

Streets of gold

The ground is carpeted with spent yellow flower petals adding even more color to the street. While the neighborhoods aren’t paved with gold, they are covered with pretty yellow hues.

Below is a picture of the branches of the Palo Verde tree laden with its delightful burden of yellow flowers.

Opuntia (Paddle Cacti) – Phoenix, Arizona

Opuntia - Paddle Cactus

“Opuntia is the most widespread of all genera in the cactus family. The genus occurs naturally throughout North and South America from as far north as Canada, through the Caribbean, and down into Argentina. With man’s help, however, this species can now be found world-wide where it has escaped cultivation and become naturalized even to the point of being classified as a noxious weed.”
Source: –

While much of the country is still in early spring, the desert is moving quickly through its yearly spring and toward what most would consider summer. As of this writing, we are still in the sweet spot of a bumper crop of blooms. The native desert plants are taking their turns in showing off.

Most of the year our cacti look like a pincushion holding onto its requisite supply of pins, but hidden in the DNA of each of these organisms is the promise of blooming beauty. Some of the blooms like our pink Opuntia (see photos above and below) look as though they would be more at home floating in a tropical drink.

Opuntia - Paddle Cactus

As pretty as these are, many of the cactus flowers have a prime bloom duration of only one day, but what a bloom it is!

You may know Opuntia cacti. They are the “paddle” cactus family. They have large, flat paddle-like growths that look similar to the ears of a number of Walt Disney characters. The picture below better shows the paddles with the pink bloom atop.

To the left of the bloom are “ladies in waiting,” so to speak. The buds will plump until nature tells them it is their turn to open and show off.

Opuntia - Paddle Cactus

A more common Opuntia would be the yellow variety. We have several specimens in our front landscape.

Opuntia - Paddle Cactus

The pile of paddles above is more than five feet tall and if the truth be told, it would probably benefit from a pruning.

This is a closeup of the flower. Note the buds in the corners of the photo.

Opuntia - Paddle Cactus

Some of the paddles have a cascade of blooms that open on the same day and form an amazing vertical line.

While I am enjoying the wonderful blooms in our landscape, I hope to share more of them with JBRish readers.

Wild West Weeds

Desert weeds along the roadside

Prior to moving to the North Phoenix area of the Sonoran Desert, I never thought about having a problem with weeds in such an arid region. After all, it is the desert with little water so there shouldn’t be a lot of weeds.

Desert weeds along the roadside


It turns out that desert plants, which naturally includes weeds, are pretty resilient. Winter rains from the end of December through February provide enough showers to enable the weeds to germinate; the more water, the more weeds.

Desert weeds along the roadside

This field at the end of our street has many, many weeds and among them are some very pretty willdflowers such as the orange Globe Mallow (Sphaeralcea ambigua) in the foreground of the photo below.

Desert weeds along the roadside

Globe Mallows grow well along the roadsides and in open fields and have a color range from light to dark orange. Once in a while one can discover a rare pink Globe Mallow or an even more rare red variety.

Desert weeds along the roadside

The Globe Mallow in the photograph above adds variety in the desert weed landscape of silver, greens and yellows.

Triangle Leaf Bursage (Ambrosia deltoidea) is an abundant weed found in many open spaces.

Desert weeds along the roadside

In fields that are left untended for a number of years, a tree may take hold. This appears to be a Mesquite of some variety.

Desert weeds along the roadside

Yes wildflowers are pretty, but weeds can be more than a nuisance. As weeds dry out, they create a fire hazard. When the temperatures rise to above the ninety degree threshold and the rains become more scarce, spent wildflowers and weeds become tinder.

Desert weeds along the roadside

It is recommended that there is a defensible space around homes to help avoid fire spreading to dwellings. There was more to know about the desert ecosystem and weeds than I ever imagined prior to my residency in Arizona. originally published this post

Gardening in the Desert – You Dirty Rat

The Sonoran Desert of Arizona can be quite a challenge. It is hard to imagine that, at one time, people lived here without air conditioning. We normally receive between 10-12 inches of rain a year in our particular area of Arizona near Cave Creek. This isn’t a lot of rain and this adds to the challenge of gardening in the desert.

Add to that problem the competition with the natural desert denizens including snakes, scorpions, tarantulas and a host of rodents.

This is the time of year when I make a daily round to look at all of the plants in our landscape to monitor their condition. When temperatures can spike to more than 90 degrees, the tipping point for some plants is very small.

For several days, I noticed that two of our plants were being nibbled. They weren’t being eaten, just ripped and the detritus left behind. From previous experience, I figured this was one of our most prevalent pests, the desert pack rat.

Rather than set a killing trap, we try to capture them with a Have-a-heart trap and relocate them. Out came the trap and at dusk I set it and placed it where I had seen the nibbling.

My most successful lure in the past had been peanuts or peanut butter. I had no more of the nuts so I put some peanut butter on a saltine cracker. Sure enough, prior to bed time I checked and we had trapped a pack rat.

Left to their own devices, pack rats have been notorious for chewing through wires and other human necessities in search of nest building materials and food. While they definitely look like rats, they are a bit, and I emphasize the word bit, cuter than your average rat (see iPhone pictures below – apologies, but these were taken in pitch black desert).

The pictures show the pack rat just before we released him so he could take up residence in a more rural part of the desert!

Spring Cactus Bloom in Arizona – The Claret Cup

We have had a wetter than usual winter and early spring and thus we are having a beautiful wildflower bloom. Our landscape cactus are showing their appreciation as well with a living bouquet for our enjoyment.

One of our courtyard features is a round planter that has hosted a Claret Cup cactus (Echinocereus triglochidiatus) for more than ten years. At one time it had plenty of room, but as you can see below, it will need to be divided and replanted within a year or so.

Claret Cup Cactus

In years past, it wouldn’t have this many blooms open at once, but its stinginess vanished this year and we are being treated to a full orchestration of its floral beauty.

Upon closer inspection you can see the juggernaut of thorns it sports that will present quite a challenge when it comes time to move or transplant it. We have a long pair of tweezers or tongs that we use to remove spent blooms or any debris that gets caught amid the needles.

Claret Cup Cactus

In the photo below, the pollen can be seen on top of the stamens. While this adds color to the picture and pollen to the air, it also seems to attract woodpeckers. For some reason they like to eat the center of the flowers and my assumption is that it is because of the pollen. After inspecting where they have been, the pollen sacks are gone — who knew?

Cactus Ghosts in the Desert

Life in the Desert

Cactus appear as ghosts in the desert
Photograph copyright by Jeffrey B. Ross – © All Rights Reserved.

Living in the desert will often present a real life oxymoron which will make us stop and take notice. Although people think of the Sonoran Desert of Arizona as a very hot place, it does have a winter season. During this period of time, from December through February (approximately), we have cloudy days with intermittent rains. This year, we had more rainy days in January than any time in the last ten years that I can remember.

Another surprise to some is that we get snow on top of the mountains surrounding the Phoenix valley and we have a frost every once in a while. In our neighborhood so far this year, we had one day with light frost, but there have been years when we have had several days with a bit more than a light frost. When that happens, we need to protect some of our sensitive plants. This is often done by covering them with frost blankets.

Once the cloth is placed over the plant, it needs to be anchored at the bottom so the cold air, that is heavier than the warmer air, does not get under the cloth.

THE PICTURE ABOVE – There are certain cactus species that people use in their landscape in the desert that are more sensitive to the cold than others and nurseries can’t take the chance of having them damaged by cold or frost. To protect the plants, they wrap them in frost cloths during the colder months. The picture demonstrates this phenomenon. When I passed by this nursery in N. Phoenix, the bundled cacti reminded me of ghosts.

Sonoran Winter Holiday at the Desert Botanical Garden – Phoenix

The Schilling Entry Arbor and Tranquility Fountain beckons seasonal guests to enjoy the winter holiday season in Sonoran Desert style.

Holiday Cheer at the DBG Entrance

Traditional festive decor can be found in many areas including the membership kiosk. While these items would be at home in any holiday display in the United States, they take on a special nuance when surrounded by nearby saguaro cacti and succulents.

Traditional Holiday accents at the DBG

It was somewhat strange to see the poinsettias taking their place next to traditionally xeric plants, many of which are native to the Sonoran Desert and other arid regions. The colors of the temporary plants play well off of the green aloes in the raised bed.

Poinsettias seem right at home next to their cacti neighbors

This yellow/white poinsettia with a bib of white cyclamen was strategically positioned near the main ticket booth. A swath of burlap is used to cover the less decorative standard pillar base.

Less traditional yellow/white poinsettias lend a nice accent when placed against the white cylcamen

During the Las Noches de las Luminarias celebration, the Desert Botanical Garden boasts – Eight thousand hand-lit luminaria bags and thousands of white twinkle lights will set the Garden aglow this winter for 21 magical evenings” – but I don’t think they were counting this rebar candelabra waiting patiently for the evening visitors and its chance to shine.

Candelabra in waiting for the evening display

The Las Noches de las Luminarias event is one of the major valley attractions this time of the year with a variety of music venues, holiday themes and a wonderful seasonal ambience set against the beautiful Sonoran Desert backdrop. If you attend, dress warmly and bring gloves!

Year of Yosemite (YOY) – Day 115 (Lupines – Valley Loop Trail)

Lupines along the Valley Loop Trail 

A wet spring brought wildflowers to Yosemite and the lupines were abundant!

As YOY followers probably know by now, one of my favorite subjects to record as I hike are wildflowers. The diversity and tenacity of nature to have flowers of such beauty that fend for themselves in the wild leaves me in wonder.

As we hiked the Valley Loop Trail, we would come across pockets of lupiines, but this particular specimen appealed to me because of the colors of the nearby ferns and the lupine leaves. The leaves have a unique (palmate) form and dark green color with lighter highlights along the ridges. Not only that, but lupine leaves have a water-gathering quality. If you look at them after a rain (or watering) you can see that the water beads and collects in strategic places on the plant.

A careful examination of the flower might remind you of a pea. Yes, it is a member of the pea family.

My wildflower ID skills are only “fair” so I am guessing these are Gray’s lupine, but they could be Brewer’s lupine. I am providing links to each below so you can decide.

Milkweed – The Beauty of A Seed

As I may have mentioned on the pages of this blog in prior posts, I volunteer at the Desert Botanical Garden in Phoenix, AZ. It is a wonderful place to experience desert flora from the Sonoran Desert and other arid regions of the world.

Whenever I work with the various dried seed pods, I am aware of the miracle of nature they represent. That a large flower can grow from the tiniest of seeds is a marvel. Not only that, but many seeds have a beauty of their own.

I recently had the opportunity to work with milkweed seed pods (Asclepias erosa). When I opened the first seed pod, this is what I saw.

milkweed seed pod

** NOTE ** These seed pods were not as dry as they would be in nature, but they had opened on their own and the seeds were removed and dried for storage.

Milkweed plays a key role in the health and welfare of the Monarch Butterfly. You can read more about that HERE. I am writing this post to show the form, function and beauty of the milkweed seed pod.

I was struck by the symmetry of the seeds and how they were aligned in a very particular pattern. In addition to the symmetry, I appreciated the rich colors displayed.

Here is the main seed structure removed from the pod. Notice how some seeds are separated from the main cluster. They fell off readily and easily separated.

symmetry along the main seed stem

As they were separated, they reminded me of tadpoles with their pearly white, almost silky tails flowing easily behind them.

silky white tails on the seeds

As they began to dry, however, they opened up on their own accord to form the fluffy wing-like structures we have come to know.

seed tails beginning to dry and fluff

In no time at all, there was a table full of the “wings.”

The tails dried to form wings

If all the seeds are removed carefully, as I learned after working with several of the pods, the backbone of the pod, so-to-speak, remains attached. It too has a wonderful symmetry and structure.

The remaining spine of the seed pod

Perhaps the picture below better demonstrates the architecture of this botanical backbone and the pointed tips which probably help to secure the seeds until, in a natural setting, they are dry enough to float away on their own.

The structure of the spine helps to retain the seeds until they are ready to fly away

The empty seed pod was slightly sticky and offered a relatively cushioned home for the seeds to await their release.

The first picture shows how similar the seeds look while clinging to the pod in the wild.

The second photograph provides a glimpse of how the seeds float away on the wind hoping to find a hospital place to root and grow.
