Although it is still technically winter here in the desert, the signs of spring are everywhere….

Signs of Spring

The plum tree at Double S Farms begins to flower.

Earlier this week, I noticed the plum tree that sits in front of the house at Double S Farms, is just beginning to unfurl it’s flowers.  I cannot wait to have some of my mother’s plum preserves in a few months :^)

Yesterday, I traveled up to an area north of Fountain Hills, AZ, which is approximately a one hour’s drive from my home.  It is also the place where I worked for over 5 years.  I was asked to do a landscape consultation for a client and so I brought my camera along to see what signs of spring I could capture in the surrounding area.

Signs of Spring

I went for a drive on one of the golf courses that I used to work on and immediately headed for one of my favorite places.  This area of the golf course borders the desert, with only a barbed wire fence separating the natural desert from the golf course.

Signs of Spring

The desert was lush and green as a result of the winter rains we have received.  Snow can be seen melting from the top of Four Peaks Mountain in the distance.

Flower buds are beginning to form at the tips of the Buckhorn Cholla.

Tiny blue flowers grace this Rosemary shrub.

Next, I went on a drive around the beautifully landscaped homes and took pictures of the plants that were in flower. 

Signs of Spring

Threadleaf Cassia (Senna nemophila)

Cassia shrubs, a favorite Australian native of mine, are beginning to flower showing off their bright yellow blossoms.

Trailing Indigo Bush

Trailing Indigo Bush (Dalea greggii)

Tiny purple petals are just beginning to peek out from the Trailing Indigo Bush.  Their vibrant purple color contrast so beautifully with the gray-green leaves of this groundcover.

Sweet Acacia Tree

Sweet Acacia Tree (Acacia farnesiana)

This native desert tree is encased in fragrant, golden puffball flowers.

Octopus Agave

Octopus Agave (Agave vilmoriniana)

This Octopus Agave, which I planted years ago, is working towards achieving it’s crowning glory – rapidly growing it flowering stalk, which will produce hundreds of new ‘baby’ agave plants.  Once it has finished flowering, it will die.

Gopher Plant

Gopher Plant (Euphorbia glandulosa)

An ugly common name, graces this beautiful succulent plant.  In spring, they are covered with vibrant, chartreuse colored flowers.

Valentine Shrub

Valentine Shrub (Eremophila maculata ‘Valentine’)

I would like to finish this post by showing you a photo that I took yesterday of my favorite shrub, Valentine.  They were in full-bloom yesterday and it was obvious that they are my favorite as they were present in most landscape areas that I had designed years ago.

Thank you for allowing me to show you some of the beautiful plants that I have been so blessed by seeing this week.  This is such a wonderful time of the year in the desert and it isn’t even spring yet!  

As winter ends and spring begins, there will be more to see….wildflowers, flowering Palo Verde trees, cactus flowers and much more!  

Early Signs of Spring on the Farm….

The sharp spines of Agave desmettiana begin to emerge

The sharp spines of Agave desmettiana begin to emerge.

In honor of Foliage Follow-up, which was created by Pam of Digging, I decided to focus on a part of the foliage of Agave – the thorns.

sharp thorns

Now, I am the first to admit, that is my least favorite part of the Agave, having pricked myself countless times.

Thorns surround each leaf of this Agave colorata

But, despite the fact that I have been pierced by their thorns, I do find beauty in them just the same.

I love that the colors of the thorns contrast so beautifully with the color of the leaves.

The thorns themselves, often have interesting shapes as well.

 The thorns of the Agave salmiana surround the entire leaf.

So, what do you do if you like the beauty of the many different types of agave, but do not want to risk getting hurt by their thorns?

sharp thorns

Well, there are three different solutions….

First, you can plant agave species, such as Octopus Agave (Agave vilmoriniana), which does not have sharp thorns.

Secondly, you can plant your agave away from walkways and the patio, and placing them farther out in the landscape, where you can enjoy their beauty, without accidentally getting hurt.

Thirdly, you can just cut off the tips of the thorns.  This is what I do for the two Agave I have growing by my front entry.  The thorns do not grow back and I can continue to enjoy the beauty of my agave, close-up. 

So, enjoy the beauty of the entire agave….even those sharp thorns ;^)

flowering stalk of an agave

Imagine a plant that lives for years, never flowering, and then towards the end of it’s life, expends all of it’s energy to produce flowers on a giant stem and then dies….

Agave Stalks Begin Growth

The story begins with an agave starting to grow it’s flowering stalk, or inflourescence.  The growth is incredibly fast, growing up to 1 ft. each day.  Depending on the species, the flowering stalk can reach heights up to 40 ft. 

almost full grown tall flowering stalk of the agave

Agave murpheyi sending up it’s flower stalk.  *I took the picture, above, at a client’s house and she referred to the flowering stalk as an ‘asparagus stalk’ because that is what it looks like.

When most people think of Agave, they think of the Century Plant, (Agave americana), and believe that it will flower once it reaches 100 years old.  This is actually a myth.  Although the timeline can vary, Agave americana does not live that long and flower much sooner.  There are over 250 agave species and most flower towards the end of their life and then die.

Actually, the length of time an agave lives is largely dependent on the species.  In my experience in the managed landscapes, most agave live approximately 5 – 15 years, once planted from a 5-gallon container.

Different Types of Flowering Agave Stalks

I am not completely sure what species this particular agave was. Note the ‘pup’ growing from the side of the agave.

There are two different styles of the flowering stalk (inflourescence).  The paniculate, above, and the spiculate, below. You can clearly see the difference in the shape and design of the stalks.

Octopus Agave (Agave vilmoriniana) I planted this agave (as a 5-gallon) in 1999 and it flowered in 2005. 

Agave Reproduce in Several Ways

Agave reproduce both by flowering (seeds) and vegetatively (bulbils & offsets).

You can read more about how agave produce offsets (pups) and how to plant them from a previous post – Pups In The Garden…Not The Soft Cuddly Kind.

The flower of an Smooth Leaf Agave (Agave desmettiana) This is an agave from my garden, which was planted in 1998 and flowered in 2007.

You can see the small bulbils (baby agave) forming among the flowers above.  The bulbils will continue to grow and will receive nourishment from the stalk.  If left alone, the bulbils will eventually fall to the ground and root under ideal conditions.  They can be removed from the flowering stalk and planted, but do best if left until they have formed at least four leaves.

Early on as a horticulture student, I fell in love with Octopus Agave and I bought my first one at a plant sale.  I planted it in a large pot and it thrived.  Years later, the flowering stalk started to grow.  I was both excited and a little sad.  I was happy because it was finally achieving it’s crowning glory….and sad because I knew it would eventually die at the end after finishing it’s life’s work.

Matured agave bulbils grown into young plants

However, that is not the end of the story….my original Agave lives on.  I took two bulbils from it’s stalk and planted them (above) and they are ready to be planted out in my garden. (Actually, I could have planted them much sooner).

**Note the little seedling coming up on the left side of the pot.  My son planted the seed, but we aren’t sure what it is.  I think he might have planted an apple seed.  We shall see….

I am talking about Agave babies, which are known as ‘pups’.

 Little pup growing

Parry’s Agave with small pup.

I knew that my Parry’s Agave, above, had a little pup growing.  I have been keeping my eye on it, letting it grow a little bit more before I take it and place it somewhere to grow on it’s own.

Now, I don’t meant to rub it in to my northern neighbors, but it was a beautiful day to be out in the garden so while I was taking pictures, I soaked up all of the warmth from the sun that I could.  It has been rather cold lately (for us desert dwellers anyway) and today was a beautiful 68 degrees.

*I promise I will be envying your weather come August….

 Little pup growing

Yesterday, on the other side of the same Agave, I had noticed the beginning of a little pup breaking through (in the far left corner of the photo).  Well, as I was uploading the photo, I was in for another surprise.  I noticed another pup growing right next to the Agave.  I now have 3 Agave parryi pups to figure out where to place in my garden (what a wonderful problem to have).  They are expensive Agave and do not produce a lot of pups as opposed to some other species of Agave.

Victoria Agave (Agave victoria-reginae) parent plant and pups.

This is another of my favorite Agaves.  How many pups can you see coming up from the larger parent plant?  I count 3 pups, but there is actually another that is not in the photo.  This Agave is also highly prized and expensive.  Victoria Agave do not often produce pups, so I am very thankful that mine has been nice enough to give me 4.

Agave lophantha with two pups

Agave lophantha with two pups.

Agave reproduce in two ways.  One is by flowering at the end of their lifetime.  The other way happens earlier in the Agave’s life span and that is by producing offsets called ‘pups’.  The Agave sends out runners underground that produce the pups.  The pups can be located right up next to the parent Agave or a few feet away.

Agave macroacantha with many pups growing around it

Agave macroacantha with many pups growing around it.

To remove, carefully expose the runner and cut with pruning shears or a sharp knife works well too.  Before planting, the Agave pup needs to form a callus on the bottom, so place in a shady, dry spot for at least a week before planting.  Agave pups can be planted out in the garden or placed in a container.  Even better, you can give some to your friends.

Personally, I would do this in the spring or fall and avoid the hot summer months as this can add more stress as the Agave pup is struggling to grow roots to absorb water.  But, that being said, Agave pups can be planted year-round.

Agave americana with pups

Agave americana with pups.

When most people think of Agave, they think of Agave americana (above).  I do love the blue-gray leaves, but I stay away from using this particular Agave because they produce large amounts of pups.  This leads to a lot of maintenance as the pups need to be removed frequently or they quickly become an overgrown mess.  I have worked with many clients who have ended up pulling out their Agave americana for this very reason.

Agave desmettiana

Agave desmettiana with two large pups. This Agave started life as a pup and was transplanted 4 years ago. It’s parent Agave flowered 3 years ago and died.

Okay, I admit, I am not the most organized gardener.  I should have taken these large pups (on the right) and transplanted them last year.  But, I promise I will as soon as it warms up.  So, please do not wait to do this as long as I did.  Agave pups do best when planted when they are small.

Agave desmettiana, (above), is a nice alternative to Agave americana as it grows large, but does not produce too many pups.  It also has smoother edges in contrast to Agave americana.

A Flood In The Garden….On Purpose

Christmas in the desert is much the same as it is around the world.  Christmas lights adorn homes and trees, with a few notable exceptions.  This is the desert after all….we sometimes do things a little differently.

Christmas in desert

First of all, we have a town Christmas tree made entirely out of tumbleweed.  It is painted white and really looks quite beautiful at night when lit up.  We have a huge celebration each year when the  lights are lit for the first time.

Christmas in desert

See…. I told you it was made out of tumbleweed.  For those of you who do not know what tumbleweed is, it is the light brown, prickly, round shrub that you see rolling through the town when you watch old Western movies. *Disclaimer – contrary to popular belief, it is rare to see tumbleweed rolling through the desert.

Christmas in desert

We desert dwellers also decorate our cactus whenever we get a chance.  Saguaro cactus is relatively easy to decorate.  There was a home we used to drive by that had 3 saguaro cacti and every year they would decorate them as the 3 wise men – they looked just great.

Christmas in desert

Water is a much celebrated natural resource and some landscapes have fake desert washes running through their front yard.  During Christmas, some decorate their washes with blue lights to signify water.

*Fake desert washes were extremely trendy, but are thankfully, on the decline.  I admit that I did design some for homeowners who insisted on having them, but I would use large boulders and embed them along the sides to imitate a natural creek bed.

Christmas in desert

Ocotillo make a great stand-in as a Christmas tree.  Just hang some ornaments and string the lights.  I may have to try this on my Ocotillo next year.

Christmas in desert

You know those nets of Christmas lights that you can spread over shrubs?  Look carefully, this homeowner spread his lights over his boulder.  I’m not sure where I stand on this one….

Christmas in desert

Agave Americana all lit up.  I love how this looks.

Christmas in desert

Some people feel that they have to throw lights on everything in their front yard.  They just do not know when to stop.  I’m not sure the lights make this Prickly Pear cactus look any better.

Christmas in desert

The majority of homes in the desert are beautifully lit and look like many of the homes where you live.  This is one of my favorites.  The arborist in me just loves how the lights define the beautiful tree trunks of the Palo Verde and Mesquite trees.

*None of these pictures are from my home.  My husband is somewhat of a minimalist when it comes to decorating the outside of our home for Christmas…a string of lights around the house is as fancy as he gets.  But, I get to go crazy with decorations indoors.

I hope you enjoyed this little glimpse of what Christmas in the desert looks like.   

What does Christmas look like where you live?

beauty with age

 Artichoke Agave (Agave parryi ‘truncata’)

Our society usually doesn’t equate beauty with age.  Instead, we celebrate youthful beauty and spend our money on trying to stay looking younger than our years.  Thankfully, in the world of plants, maturity is something to be celebrated.

In the case of the agave, age equals beauty.  A leaf of an agave plant can live for up to 15 years.  The leaves are etched with beautiful patterns called ‘bud imprints.’   These delicate patterns decorate the leaves in numerous different ways depending on the species, as you can see in the photo of my Artichoke Agave (Agave parryi var. truncata) above.

beauty with age

 Cow’s Horn Agave (Agave bovicornuta)

Along the sides of agave leaves are small thorns, called ‘teeth.’  Agave leaves stay in bud for 2 – 3 years.  The teeth from the leaves imprint on the other leaves while they are held tightly within the bud, which is how their delicate patterns are formed.

beauty with age

Depending on the species, some bud imprints are more obvious, while others are more subtle.

The fibers from the leaves of the agave are used for weaving items such as bags and mats.  The leaves are also used to feed cattle in areas of Mexico.

beauty with age

 Agave ‘Durango Delight’ (Agave schidigera ‘Durango Delight’)

Some agave leaves have filaments along the edges.  Most agave end with a sharp terminal spine, which should be taken into consideration when you decide where to plant them.  You do not want them in high traffic areas where people can be pricked, (believe me, it hurts). 

beauty with age

 Mescal Ceniza (Agave colorata)

Because agave store water inside their leaves –  their leaves are thick and succulent.  Some of my favorite agave species are Artichoke Agave, Mescal Ceniza, and Victoria Agave.

Agave salmiana

 Agave salmiana

I saw this agave (above) next to my gym, and I was very impressed by its teeth.  They remind me of ‘claws.’

Beauty With Age

There are between 200 – 250 different species of agave, in all shapes, colors, and sizes.  Some of my favorite features of agave are how beautiful they are with their leaf shapes and imprints.  Secondly, their low-maintenance and drought-tolerance also make them a favorite in my garden.

Victoria Agave

 Victoria Agave (Agave victoria-reginae)

Agave is amazing plants, and I am a huge fan.  There is much more information to cover, which I will address in a future post.  But, I will answer the most common question that I am asked about agave, “No, they do not live for 100 years.”  You may be surprised at the real answer…

But, that is for a later post…

Winter Flowers, Fragrance and a Funny Name

Skeletons in Desert Areas can be hidden or along a popular path

Unveiling the Mysteries of Cactus Skeletons in the Desert

When you think of a desert, you likely picture vast stretches of sand, scorching sun, and towering cacti. These iconic desert plants, such as the saguaro cactus, play a crucial role in the ecosystem and are known for their remarkable resilience in arid environments. However, have you ever wondered what lies beneath their impressive exteriors? On a recent walk through the desert, I found these skeletons. We’ll delve into the fascinating world of cactus skeletons in the desert, shedding light on the woody remains known as “ribs” that provide crucial support to these giants.

Saguaro Cactus: A Desert Sentinel

The saguaro cactus (Carnegiea gigantea) is arguably the most recognizable symbol of the American Southwest’s deserts, particularly the Sonoran Desert. These imposing cacti can reach heights of up to 60 feet and have a distinctive columnar shape, often adorned with arms that reach out like welcoming gestures to the desert’s harsh conditions.

A Closer Look at Cactus Ribs

One of the most intriguing aspects of the saguaro cactus is its internal structure. Beneath its fleshy, water-storing exterior lies a hidden framework known as “ribs.” These ribs are not bones, of course, but they serve a similar purpose in providing structural support to the cactus.

The ribs of a saguaro cactus are typically woody and arranged in a vertical pattern within the plant’s body. They extend from the base of the cactus up into the arms, acting as a skeletal framework that gives the saguaro its characteristic shape and enables it to thrive in the harsh desert environment.

Why Do Cactus Skeletons Exist?

The presence of ribs or cactus skeletons in the desert serves several essential functions:

  1. Structural Support: The primary role of cactus ribs is to provide structural support to the plant. This support becomes crucial as the cactus grows taller and heavier, preventing it from collapsing under its weight.
  2. Water Storage: While ribs are not directly involved in water storage, they indirectly facilitate it. The ribs help maintain the cactus’s shape, which, in turn, ensures the efficient storage of water in the fleshy tissue surrounding the ribs.
  3. Growth and Survival: Cactus skeletons play a vital role in the cactus’s ability to grow and survive in the desert. The ribs allow the saguaro to withstand strong winds and maintain its upright posture, ensuring optimal sun exposure for photosynthesis.

As I began my trek through the desert, I found beautiful specimens of cacti, plants and even some wildlife, but I also found a few skeletons as well…..

Saguaro cactus have strong ribs which help them grow very tall

 Mature Saguaro

This beautiful Saguaro was one of the first cacti that greeted me on my walk.

Skeletons in Desert areas can appear as dead wood piles

The first skeleton I came across was from a Saguaro cactus; part of it still standing upright.  You can see where top part of the skeleton has fallen to the ground after the cactus plant has died.

Look inside this dead saguaro to see the rib structure

Here it is close up.  The decay is till present as you can see inside.  The woody remains of the saguaro are called ‘ribs’ and are what supports the Saguaro cactus.

Skeletons in Desert areas start as fleshy plants

Above, is a photo of a Saguaro that had just fallen.  You can easily see the ribs.  Whenever a Saguaro cactus would fall in a landscape setting, we would move it to an out of the way area where it could decay.  Then we would take the ribs and put them back into the landscape as a display.  Saguaro ribs are considered a beautiful accent in the desert landscape and are prized by many.

Some Skeletons in Desert areas are just bones

Skeletons in the Desert can be Building Material

Native Americans used Saguaro ‘ribs’ to build roofs, walls and even furniture.  Another use was that they would make long poles that they used to knock off the Saguaro fruit, which is edible.

Saguaro are not the only types of cacti that leave behind skeletons….

Teddy Bear Cholla have unique skeletons

 Teddy Bear Cholla (Opuntia bigelovii)

 Teddy Bear Cholla (above), also has an interesting skeleton.

Above, is a photo of a segment of Teddy Bear Cholla that is in the process of decaying.  You can see the woody skeleton starting to show.

Cholla skeletons have interesting architectural shape and designs

Cholla skeletons are sometimes used as walking sticks.  Artisans also use cholla skeletons to make southwestern forms of art.

Cactus Ribs are the Backbone to the Desert Cactus

Cactus skeletons, or ribs, are nature’s ingenious solution to help these iconic desert plants thrive in extreme conditions. They offer support, aid in water storage, and contribute to the cactus’s overall resilience. The next time you encounter a towering saguaro cactus in the desert, take a moment to appreciate the hidden framework that enables this remarkable plant to stand tall and flourish amidst the harsh desert landscape.

Please note that it is illegal to remove Saguaro and Cholla skeletons from the desert, unless you have permission from the owner.  Specimens can sometimes be purchased at certain plant nurseries that specialize in cacti.

So do as I do…..enjoy them out in the desert and take lots of photos.

Care of Cacti

 Agave macroacantha with ‘Firesticks’

Succulents are some of my favorite types of plants. I especially like the smaller agave species such as Agave parryi, Agave victoria-reginae, and Agave bovicornuta to name a few.

Let’s talk a little about how to care for cacti and succulents. 

Care of Cacti

 Silver Spurge (Gopher Plant)

Agave, cactus, yuccas, as well as other succulent plants, can continue to be planted during this month. Warm soil temperatures are necessary for succulents to grow and they do best when planted during the warm season.

Care of Cacti

 ‘Baby Rita’

Contrary to popular opinion, newly planted succulent plants need to be watered in order to become established and grow a healthy root system.

Care of Cacti

Established cacti appreciate some supplemental water during the summer months, (especially this summer with our non-existent monsoon). I typically water large cacti with a garden hose about once a month in the summer unless we have had a lot of rain.

Lophocereus schottii 'Monstrose'

Care of Cacti, Lophocereus schottii ‘Monstrose’

Some cacti and agave plants may show signs of yellowing in the summer. This is usually due to high temperatures. Be sure to give them some supplemental water if you notice the yellowing. Usually, the yellow color disappears once temperatures cool down in the fall.
