Grandma and Grandpa generously flew us out to Arizona for the weekend.

It was a short, but sweet, getaway to the breathtaking Superstition Mountains.  We spent the weekend in the pool with the kids, soaking up as much sun as we could…hoping to pack some in our suitcases and bring home to Minnesota.  That sunshine stowaway plan didn’t work.  I couldn’t believe the thick fog we arrived home to.

While swimming in the pool with my children, and listening to my daughter’s enthusiasm over flying above the clouds and mountains, I pondered on what is really important in life to me. Stripped away of all my daily distractions and desires, I could clearly see it isn’t money or fame.  What I value more than ever are the small and simple moments of wonder and amusement with the people I love the most.

The little things in life matter to me now more than ever.  I know, cliche, but so very true.

When I moved to Tucson, it was like moving into an alien landscape. I grew up mostly in Massachusetts, so I was used to maples and oaks and grass. Here it is the cacti that stand out. The most common species around here are part of the genus Opuntia: prickly pear and cholla. I see TONS of them along my running route, so today I will share a bunch of pictures of them.

Most folks seem to have heard of prickly pear. Here’s a photo of the common Engelmann prickly pear under a mesquite tree:

Engelmann prickly pear

All opuntias grow in segments. The stem stops growing when it gets dry, and new segments form when the rains return. One of the coolest things about them is you can take a segment off the plant, place it on the ground and water it, and it will grow into a new plant. In fact, most opuntias reproduce in this manner rather than using seeds. Many times I have seen Tucsonans who want to plant prickly pear along a wall, for example, just break several pads off an existing plant, place them along the ground by the wall, water them, and watch them grow.

Prickly pears generally have flat segments, often called pads. Chollas however have cylindrical segments. In this picture below you can see three types of opuntias. First, Engelmann prickly pear, as you saw in the first picture. Then there are beaver tail prickly pears, named for the pointed oval shape of their pads. And behind them you can see taller almost tree-like things with segments with spines all over them; those are cholla, commonly called chain fruit or jumping cholla.

Engelmann and beaver tail prickly pear, jumping cholla

Jumping cholla are called that for a reason. If you walk past them and get just a bit too close, it seems like a segment will jump onto you! What has really happened is you brushed against some of the barbed spines and the segment attached to you and came off the plant.

This next is a picture of Christmas cholla. Its stems are much thinner than the chain fruit cholla, and you can see the small red fruits growing on it. This red fruit generally shows up late in the year, thus the association with Christmas.

Christmas cholla

Here is another type of prickly pear. I tried to find a specific name for it, but my kids hid my Plants of Arizona book after last using it for a Nature merit badge. Anyway, as you can see this type of prickly pear is darker green. The pads are also smaller and more thickly spined.

More prickly pear, mystery type

Here you can see that not all cacti are green! These purple prickly pears are some of the coolest looking things on the planet, in my opinion. You should see them when they bloom with big huge yellow flowers!

Cactus wrens love to build nests in large cholla, and you can see one in this picture.

Cactus wren nest in cholla

If you squint and look on the right-hand branch of this cholla you can see a cactus wren.

Here you can see a bunch of cholla segments and fruit fallen to the ground. The segments have a better chance of forming a new plant than the seeds do, as the seeds are generally sterile.

Cholla fruit and segments on ground

This is an Indian Fig prickly pear. They grow tall; if you look toward the top right of the picture you can see a pad sticking up over a branch of the mesquite tree. They also have hardly any spines on them at all, which makes them popular in landscaping around houses. I had one just start growing in my back yard and I let it grow, and it is gorgeous now!

Indian fig prickly pear

Some kind of prickly pear is found in every single one of the lower 48 states. So keep your eyes peeled!

Hiking along a desert trail away from houses and neighborhoods, you will encounter homes of a different kind. Unique to the Sonoran Desert are large colonies of Carnegiea Gigantea, also known as Saguaro Cactus. Unlike homes which can take 2 to 3 years to build, it takes Saguaro cactus about 150 years to reach maturity, with arms developing when the plants are 10 to 15 feet tall. The Gila Woodpeckers and Gilded Flickers don’t mind, they drill their holes into the flesh of the cactus and build their nests inside, long before their homes are completed. They share their living space with others, it is nature’s version of condo living!

The Saguaro cactus is a protected species in Arizona, you will need a permit and a moving company to have it removed and relocated to your property. It can be very heavy, our Saguaro weighed in at 1500 pounds and arrived on a large, flat bed truck. The movers dug the hole with a jackhammer. Because the roots are shallow, the hole does not need to be that deep, but desert soil tends to be rocky. The cactus was lowered from the truck into the freshly, dug hole. The expense of purchasing a large Saguaro and hiring a moving company can put a dent in your landscape budget.

It is possible to purchase small Saguaro at nurseries or gardens, but considering how slow they grow, it might be worth the expense to invest in larger ones. These beautiful, unique cactus will be yours to enjoy for years to come!

Grand Canyon:

I received a little more info on the details of the trip. It looks like it will not be rim to rim, but I don’t think that’s a dealbreaker. While I would still like to hike that, the itinerary is quite appealing. I guess the rim to rim hike is more populated and built-up (and has mule poo!) while they will be hiking more remote areas. I talked to my mom about it last night and I think I’m going to go for it. I’ll probably register next week. Yay! (PS – San Diego Tracy, I’ll still come out to visit you and we can do the rim to rim hike with your buddy)

Spike, Moe, & Frieda:

It has been a while, but I think it’s going to be worth it! Here is our “all-growed-up” cactus & random succulents:

Spike!

& the gang!

The gang consists of Frieda (top right), Lechuguilla (bottom right), random succulent (bottom middle), Living Stone (top left – ugly elephant toe-looking thing), horsey & rocky. Sadly, we lost Moe in a tragic drout incident. Oh! And it looks like a runaway succulent “leaf” trying to propagate (top middle).

And just so everyone else in the office doesn’t feel left out, here are the rest of the plants.

There are 3 separate cacti here, in order from left to right as pictured:   Aloe ferox “Fierce Aloe,” Aloe zanzibarica and thirdly Echeveria Perle von Nurnberg.     The Echeveria is a hybrid of E. gibbiflora v. metallica and E. potosina.   The first two species are apparently endangered according to Wikipedia.  Interesting that I recently bought them at Home Depot or Lowe’s.

White Sands Sunset

This is the last image I made at White Sands on my last trip. The sun was barely above the horizon, and the soft golden light enveloped me in a wave of anticipation. The low angle of the setting sun gave the ripples on the dune a palpable texture.

I think this image does a good job of communicating the fickle nature of the dunes, and the uncertain fate of the life that exists there. One yucca is partially covered by the advancing dune, and another is completely buried except for the dead stalk of it’s blossoms. The exaggerated ripples across the face of the sand suggests the constant movement that is the essence of the dunes.

As ominous as a six foot electric fence topped with barbed-wire.  Only slightly prettier.

Phoenix, Arizona is the fifth most populous city in the US that rises in the desert as an urban oasis. And The Valley of Sun has a lot of it, sun, that is. But hot weather and natural adventures is mostly what this city of the South has to offer. I found it difficult to locate any interesting things to do while in Phoenix. The Botanical Garden was nice – tall and ginormous cacti, hurrying lizards midning their own business, and scorching sun, even in mid-October. I have to admin that the red hue of the rocks found in Arizona provided for some beautiful facades of buildings downtown, and that those administrative buildings looked more like art museums than office buildings thanks to the red color.

That said, I want to point out that an Arizona sunset is the closest a human being can ever get to an awe-envoking, heart-stopping, breath-taking glimpse of heaven here on Earth. Particularly if you happen to be driving from the Grand Canyon to Phoenix and you start to descend as the sun goes down. There are no words to describe the exquisite colors and divine shapes that will blossom in the sky, fervently burning, rapidly transforming and unbelievably bright, an absolute nirvana.

Desert Packrat

White-throated Woodrats (Neotoma albigula), are also known as Packrats because of their habit of collecting all kinds of stray junk, plants, and sticks and bringing them back to their nests, which can be piled high. We had heard that they like “shiny things“, and even found a cell phone on one nest in the desert. It is best to keep your Arizona Plants cleaned up, to deny them a “nest” on your property.

They can be very destructive to homes, garages, and it is not uncommon to have them build nests inside car engines and then chew on electrical wiring. The one pictured here was right where we don’t mind having it, out in the desert and enjoying one of the many prickly pear cacti.

Each day I work on campus, I walk past Lucy’s Garden. She’s a big ole dog in a picket-fenced succulent garden with palm trees, cacti, and other interesting plants of the south.

Something is always blooming in the tiny area with varying shades of green, yellow, purple, and red calling to me as I pass. A few times I’ve remembered to take photos so I can paint it later.

This is my first of hopefully many from this enchanting garden.

SOLD © Pam Van Londen 2007 Christmas Cactus 1 acrylic on canvasboard on 8 x 8 x .5 canvas

This holiday cactus looked great in the store and for a few weeks in December. I was able to paint its portrait before I almost killed it. It’s doing well now but has no blossoms.

There was a query on my previous post – do I know of any list of overwintering houseplants?

There may be some confusion here. The houseplants I was referring to are those plants (mainly perennials and shrubs) of tropical and subtropical origin that are adapted to low light levels – and hence are suitable for growing indoors in further north. So that would be nearly all of them – apart from the desert cacti, which need as much light as possible year round.

By all means keep posting queries where anything on this blog is unclear.

If you enjoy being out in the yard, but have never managed a desert garden on your own, it is much less daunting than you might expect. To begin with, take stock of your yard. Walk around and look at the plantings. Observe which areas of the yard get full sun, partial sun, and shade. Note the variety of plants and trees that are there. Take note of the irrigation system and how much water your plants are getting. Make a list of the local resources and contact them for information.

Weekly maintenance will keep your garden looking good and the tasks manageable. More than once a week is icing on the cake and less than that requires a larger block of time. Other things to consider when it comes to yard maintenance are time of year, weather conditions such as rainfall, monsoon storms, and wind. We do get some pretty strong winds at all times of the year. Plants tend to dry out and trees will drop considerable amounts of litter.

Obviously, the size of your yard is important. Taking on the backyard yourself and hiring a landscape company for the front yard tasks might prove workable and not overwhelming. In many communities, the HOA will contract with a landscape company to maintain the neighborhood’s front yards. This service is paid for through HOA monthly dues.

Whether you manage the yard on your own, or hire a landscape company, there are some things that people do to their yards, and more often than not it is the landscape companies that do them, that are particularly annoying. Shrubs, large and small, were never meant to resemble gumdrops. Trimmers, gas powered or electric, are the culprits. For some people, once that trimmer is in hand, they get carried away. Before you know it, their bushes are all in nice, round shapes, or worse, flat on the top, round underneath. Bottom line, desert shrubs grow beautifully on their own, leave them alone. The woody varieties will need to be trimmed back occasionally to encourage new, healthier growth, no trimmers are needed for that task.

Blowers are another over used device. Using the blower once every few months is really all that is needed. Besides being very noisy, they add to air pollution and aggravate allergies. The adjustable rake I mentioned in my first blog, is very effective in managing yard debris. Park the blower in the garage, use it sparingly.

When it comes to trimming your trees, it might be wise to leave that job to the professionals. By professionals, I do not mean landscape companies. Remember that resource list? Call your local nurseries or the Botanical Gardens, or use that list and get referrals. It is easy to get carried away with tree trimming, before you know it, you have wiped out the tree. At the very least, enroll in a tree pruning class. Many classes are free of charge.

The irrigation system needs monitoring despite the season. Heads have been known to fall off and leaks can occur in the tubing. Annoying, but nothing you cannot fix yourself. I have had leaks in major lines, which requires digging into the soil, isolating the leaks, and plugging them with goof plugs. Again, nothing you can’t do yourself. Cacti do very well not connected to the system, once established, they do fine with an occasional hand watering.

Checking the water system to make sure the heads are working properly, adjusting for the season and rain frequency, making sure the soil is not saturated in any one area, is a good idea. Rabbits and other small critters like to chew sprinkler heads. The irrigarion system is amazingly easy to maintain. The materials you need are readily available online and at places such as Home Depot. The system timers are more complex, but nothing that would require an expert to manage.

Enjoy your time in the garden!

Alright, I hear you! A few folks have been asking to see more of my photography. I started out the blog as a way to share my work, but I’ve noticed that lately I’ve been so excited about what other people are doing that I’ve kinda let my stuff fall by the wayside. I didn’t do it on purpose, I promise. But since you’ve been clambering for more, here are a few that I took recently!

Flowers aren’t really my thing — this might be the only time you see flowers at all from me on this blog! — but I was visiting the Botanical Gardens in D.C. a few weeks ago and was absolutely blown away by the beauty there. Never been? Time to fix that! The gardens are conveniently located right next to the Capitol, and best of all they are FREE! Your tax dollars pay for this, so go enjoy it. The gardeners are so wonderful. I spent a lot of time with an adorable lady named Jean who showed me all sorts of neat behind-the-scenes secrets about the gardens. I encourage you to go see more for yourself!

It is a beautiful Sunday afternoon in the Valley, quiet and very peaceful. As I look out over the yard and beyond, I am always amazed at how much color there is in the desert. At this moment, a hummingbird is hovered over a bright, Red Justicia flower and stunning, pink Oleander flowers peek out over the fence. In the distance, I can see the deep, green color of grass and trees. The Yellow Bells are in full bloom as are the Yellow Dot, the purple, orange, red, white and yellow Lantana. The contrast of the white flowers of the Blackfoot Daisy and the beautiful, deep, purple flowers of Langman’s Sage is a desert delight.

I am not always certain what colors will pop up in my yard at any time during the year. I am not picky about color. If a plant survives past its first summer, let alone blooms, I feel incredibly lucky!

When we moved to the Valley, I had no idea what plants to plant in the yard. I was totally unfamiliar with desert plants, we arrived here from the midwest, the landscape is the reverse of what it is in Minnesota. We enjoyed spending time on the patio, container plants seemed to be the best way to become familiar with plant varieties. The containers added color and made the patio look nice.

I headed to Home Depot to search for pots and take a look at their selection of desert plants. I found many nice pots at reasonable prices. The plants are hit and miss. I learned to take a good look at the bottom of the containers to make sure roots are not growing out of the holes. It is a good idea to actually lift the plants out of the containers and make sure the plants are not root bound. Take a look at the leaves and note the general appearance of the plants. Asking where the plants are from is another good idea. You will have more success with plants grown here in Arizona.

Taking a stroll through the local nursery is a great way to become familiar with desert plants and ones that make good container plants. The staff are usually knowlegeable and helpful. Everything seems to be a bit more expensive but in the long run you might be more successful making your purchases there, at least in the beginning.

Containers are not just for the patio. Mixing planters among cacti or nestled in vigorous ground cover, pots of varying sizes grouped together by a fence next to a colorful bench, smaller containers under patio tables, containers under trees or between trees, next to the pool or hottub, all add interest to the yard. Containers help create little nooks, secret gardens where you can go and enjoy the beautiful Arizona weather.
