Lonely Cactus and a Giant Plastic Fish

At a visit yesterday to the Tucson Botanical Garden I found three of my passions combined: gardening in hot dry climates, art in gardens, and picking up trash from public areas.

I’m going to start with the picking up trash part in this post. [Full disclosure: I am a member of a Tucson environmental group called Trashy Divas and twice a month we pick up trash in public parks and along side streets.] Now, back to the ocean debris art.

Ocean debris turned to sculpture

The TBG always has interesting sculpture on exhibit in and around its many, small demonstration sites for drought-tolerant plants. Sometimes the sculpture is small and suitable for a residential garden. Other times the art is large — the ideal size for a public garden.

The fish at the top of this page, Priscilla the Parrotfish, is one of several sculptures now on display at TBG and it is large. The large Jellyfish, which hangs near the entrance, is unnamed for now. TBG is running a campaign to name it. I voted for the name Bubbles.

Both these sculptures were created by an environmental group called Washed Ashore based in Bandon, Oregon. All the materials have literally been picked up off Oregon beaches, then cleaned and refashioned by artists.

A few steps away from Priscilla the Parrotfish at TBG is another figure, a Rockhopper penguin, a native of islands around Australia and New Zealand. Nearby in the trees are a group of smaller jellyfish in sizes suitable for backyard gardens. One wonders if any of the materials in this penguin crossed the ocean from Australia to Oregon.

Another bird sculpture in black and white is Sebastian the Puffin. As a work of art it must be close to 10 feet tall; in real life puffins are only 2 to 3 feet tall.

Here are close-ups of elements that have gone into these creations. The image on the left is some of the plastic trash that makes up Priscilla the Parrotfish. On the right is the foot of Sebastian the Puffin with California poppies blooming behind. Every bit of this debris was at one time bought by someone in a store for some purpose, used and then discarded–perhaps in the ocean or perhaps nearby in a waterway leading to the ocean.

Puffin feet

The lesson here: dispose of your plastic trash properly in a garbage can or recycling bin. As charming as these art works are, we do not need any more of them made from plastic debris.

On to the lonely cactus

From the 1950s through the end of the 20th Century, lawn was the landscape solution for builders of large developments in the Midwest and East Coast. Sow grass seed to cover the lot with lawn, then plant a very small tree or a couple of small shrubs and call that landscaping. Cheap and fast.

Here in the desert, developers have continued this “fast-and-simple” approach to landscaping around new homes, but with one big change: instead of lawn they dump a truckload of rock mulch and spread it all over the lot. Then plant a small cactus and very small tree and call that landscape.

So now there are solo cactus in front of homes all over the Southwest. In reality cacti look better when planted in groups and give a home a more established, upscale appearance. Adding a mix of larger rocks adds to the sense of a natural environment.The image below shows denser plantings of a mix of cacti on a berm–an artificial hillock. You can see another example of planting on a berm here.

But this is not to say that an all rock mulch garden can’t be beautiful as this newish Japanese-style garden at TBG demonstrates. But you will have to rake it every day to keep it looking good.

And finally, back by the butterfly house, there is a new addition to Tucson Botanical Garden: a garden flowers kaleidoscope. The tube the girl is looking through has been created with a kaleidoscope refractive lens. It was fun to look through as the bowl of flowers spun slowly around.

A final note: The Washed Ashore sculpture will be on display through May 18.

Happy Solstice – winter and summer!

My wish on today’s Solstice is that 2021 will be a better year for everyone! 2020 can’t end soon enough!

The light at the end of the proverbial tunnel is brighter now that the roll-out of COVID 19 vaccines has begun.

Now, you can make the natural world better this coming year by planting a tree that’s suitable for your climate to cast shade on your garden and home. The world continues to grow warmer and a tree will help cool it down a bit over the coming decades.

And, if you still have a grassy lawn, make 2021 the year you remove it and plant water-wise shrubs instead. Lawns are fine in wet climates, but an unwise use of water in hot dry gardens.

And, keep in mind that by planting long-living shrubs and trees you are also providing homes for Mother Nature’s other creatures, especially birds and insects.

May your garden thrive in 2021!

All hail Queen Agave new ruler of the front lawn replacement

Front yards don’t look the way they used to.  For generations, the American standard  from coast to coast has been green grass as a carpet in the front of the house.  Mowed once a week. It was all very orderly and not many decisions were involved.  The homeowner’s “garden personality” was expressed in the choice of shrubs or flowers chosen to line the edges of that green carpet like a fringe.  Lawn replacement didn’t even enter people’s minds.

(NOTE: It is still too hot to plant in most of the Southwest, so I am writing about Lawn Replacement again!  Wait until the temperature drops below 90 degree F before beginning Fall planting.)

Now as homeowners in the West under the pressures of drought and climate change rush to remove these conventional front lawns no clear single standard for replacement exists.  What many homeowners know is that the grass in front of their house is “bad” and needs to go.  The Water Department said so.  And even offered to pay part of the replacement costs.

Homeowners are facing new lawn decisions
gold lantana
Gold Lantana is one tough ground cover that thrives with very little water and a lot of neglect. Too much fertilizer will make it bloom less. It comes in a variety of colors ranging from white to blue to pink to orange. The white and blue do NOT do well as lawn replacement.

“Agaves? Aloes? Aeoniums? Or maybe a single color field of gold Lantana?  Yeah. That sounds good.  Just one type of plant and one color. Oh–but will that be too much gold? Would pink Lantana be better?  Or maybe native plants?  Or maybe… [pause] Or maybe I’ll just hire someone to do it for me.”

While homeowners may be overwhelmed by these decisions, many of the landscapers installing these new front yards are not.  Agaves seem to be becoming the basic plant around which low water usage gardens are being created.

Now I have nothing against agaves.  Without them we wouldn’t have Margaritas.  And long-nosed bats would simply be another vanishing species if agaves disappeared.

Moreover, these plants are practically indestructible with a lifespan of several decades.  (Yes, I know they are called “century plants”, but they really do not live for a 100 years.) Professional landscapers love plants that they can stick in the ground and then count on to remain alive long after they have left the scene. They do not want to hear complaints about plants dying on previous jobsites.

So agaves it is.

But these plants need visual softening, some other plants to add visual variety.  Even the plant-and-go landscapers recognize that but rarely do ornamental grasses become their first choice as “other plants”.

The lawn by this row of Pampas grass has since been removed. Behind it is a dull gray block wall. In winter cut the Pampas grass back to 18 inches in height.

I wish they would.  From a 15 foot tall Pampas Grass (Cortaderia selloana) to line an unpainted block wall to 6 inch tall Mondo grass or Lilyturf (Liriope muscari) to cover a gentle slope in green, ornamental grasses are interesting and beautiful additions to a drought-tolerant garden.

Agave, deer grass, blue fescue, rocks Hot Gardens

A Large Agave surrounded by grass and rocks
This mix of Blue Fescue (Festuca), Deer Grass (Mulhenbergia rigens) and Agaves along a simulated creek bed filled with rocks is a classic image of lawn replacement using drought tolerant grasses.  It takes an artistic hand to site these plants in a way that looks good.  It also takes money.  Creating artificial streams can be very expensive.

Grasses to line a garden path
Pennisetum setaceum 'Rubrum' Hot Gardens

Far less expensive is Red Fountain grass (Pennisetum setaceum ‘Rubrum’) planted along a sidewalk.  It becomes a colorful addition to a drought-tolerant garden. It is especially attractive in  Autumn when it blooms and dances in the wind. The nearby Agave is good for structure, but not for gracefulness.

Next are a pair of photos showing before and after Mexican Feather grass (Nassella tenuissima) was added to a garden of Agaves and Aeoniums.  Sadly, the “Before” photo with chopped off Feather grass in a distant corner was actually taken in September of 2018.  The “After” was taken in 2016.  Why the homeowner decided to whack off the Feather Grass before he put the house up for sale is beyond me.

2 desert style lawn replacements and a confession about travelling online

I’ll start with the confession: I sometimes take “drives” around cities and towns on Google, using Google’s street view.  It gives me a chance to look at how people garden in places I may not have visited.  I also look for examples of lawn replacements where green grass in front yards has obviously been removed and drought tolerant plants installed instead.

Most recently I “drove” around Tucson, Arizona and El Paso, Texas and, instead of lawn replacements or dry, sun-baked lawns, I saw a lot of non-gardens in front of homes. What I consider non-gardens are front yards with a random bush or two here or there, nothing seemingly planned or cared for.  These spaces may have rock mulch, but as often as not, they don’t. And they are not native plant gardens either. Lawn replacement wasn’t even an issue in those places.

Both cities have low annual rainfall –10 inches for El Paso, 12 inches for Tucson–which puts them both clearly into a desert climate category with most of the rain coming during the summer monsoon.

With a little planning, however, non-gardens can be transformed into attractive spaces that will please the eye and increase property values.

Full disclosure: These examples below are lawn replacements.  Instead of  starting with non-gardens these homeowners removed thirsty front lawns temporarily creating “non-gardens”.

Here are two examples I particularly like. Neither require much maintenance at all after they are established. (And for 4 more landscaping ideas for hot gardens, go here.)

Lawn Replacement garden #1

decomposed granite front lawn replacement hot gardens

These homeowners stripped out the grass and planted a border of non-thirsty desert plants in a curving shape around a plot that looks like bare earth but is in fact decomposed granite. The decomposed granite protects the underlying soil from erosion during heavy rains and is excellent for weed control.

Lantana ground cover mixed colors
The low-growing Lantana (Lantana montevidensis) comes in many colors these days.

Among the plants in this border near the house are several varieties of Agaves plus Lantana with orange blooms.  Lantana flowers for months on end and needs very little water. The Agaves can survive with almost total neglect.

In the foreground are Aloe, iceplants (Delosperma) and a lone clump of Mexican feather grass (Nassella tenuissima) in bare soil that once had wood mulch on it. The bare soil looks washed out and uneven in contrast to the decomposed granite surface.

Lawn replacement garden #2

This second garden is also drought tolerant, although it definitely needs more watering than the one above.

Drought tolerant garden in late summer hot gardens net
This garden is new within the last 3 years. Wisely, the ground is covered with organic mulch.

Despite the fact that many of the plants are desert natives, they give the impression of being abundant in an almost “English garden” style with mounds of green plants with leaves of contrasting colors and shapes. Because this photo was taken in late summer only a few blooms are left on plants.  Among the plants are the almost leafless Palo verde trees (Parkinsonia x), deer grass (Muhlenbergia rigens), and the Mexican Bird of Paradise (Caesalpinia mexicana) with its long-lasting orange blooms.

The garden design also includes berms, shallow “hills” created artificially, to give more privacy to the home. One good thing about creating berms is that in the process of building up the pile of earth you can add nutrients all the way through to the old bare earth below.  These berms are covered with wood mulch to provide both cover for the bare soil and food for the plants.  The homeowners have chosen a light color decomposed granite for the paths. It also comes in a variety of other colors.

Here is a second view of the home. I’m not sure what the plant in the front by the rock is, but it looks as if it is failing.

Lawn replacement gone wild with blue bottle ornaments

This astonishing landscape design was developed by the homeowner in an upscale neighborhood that is under strict watering limitations. She told me she had no art training so I think of her as a self-taught landscape designer, sort of a “Grandma Moses of garden planning”.

Blue Bottle lawn replacement Hot Gardens net
Encouraged by the water department, this homeowner replaced her lawn with drought tolerant plants and dozens upon dozens of garden ornaments. To one side there is a long row of ornamental  grasses.
Circular Flower Bed in Blue Bottle garden Hot Gardens net
Circles within circles seems to be her main design motif. At night lights surround these plant beds. See below.

Instead of planting an ordinary selection of cactus and succulents, she let her imagination take flight by adding blue bottles, wind spinners and, at night, lights encircling the plant beds. And, from the empty pots and bags of mulch still stacked around the garden it appears she isn’t done yet.

She inspired me to check out garden ornaments on Amazon and I found this attractive wind spinner and some interesting solar lighted lilies.

What do you think of this garden?

The homeowner’s love of wind spinners is quite obvious.
Plumeria tree Hot Gardens net
Among all the cactus and succulents is this tropical plumeria tree. It requires more water than most of the other plants. All the plants in this garden appear very healthy.
Blue Bottles fan ornament in Pasadena Hot Gardens net
While the blue bottles are the most conspicuous visually, there are actually many more wind spinners in the garden.
When the homeowner/designer said she had added lights to the garden and invited me to come back after dark to see it, this is what I saw. It is a quite subtle light display.

Take the “screwdriver test”. Your lawn will thank you.

edge grass, agave, iceplant
Replacing a traditional front lawn with other drought tolerant grasses makes good sense.

Officially, the drought is over in California.  At least Gov. Jerry Brown said so.  But in Southern California and Nevada and Arizona and parts of Texas–even in New South Wales in Australia–drought conditions continue.

So many responsible homeowners are replacing their front lawns which we all now realize are nothing more than giant green sponges.  Keeping a lawn behind the house, however, can make a lot of sense, particularly as a play area for children.

And that backyard lawn needs regular watering.  But if you are not sure if you are watering your lawn too much or too little, here is an easy test:

Take an 8 inch screwdriver and push it into various places in your lawn about an hour and a half after you have watered.  If the screwdriver goes in easily, you are watering enough. You may even want to consider cutting back a bit on water.  If you cannot push the screwdriver all the way in, you need to increase the amount of water for the lawn.

Simple, right?

If you still love the look of a grass lawn, consider planting Buffalo Grass, a native grass of the American Plains. It has been hybridized in recent years so it now looks like a traditional lawn, rather than fodder for roaming buffalo herds.  It greens up in warm summer months, then goes dormant and brown in the winter. If you decide to go this route, be sure you plant plugs — not seeds. A Buffalo Grass lawn needs little or no watering at all.  Not much mowing either. (Note: this is not Buffelgrass, an invasive African grass that now threatens saguaros in Arizona.)
