Design: TJ’s framework drawing for pool and landscape. This is the third post in this series. You can read the first post here.
Bucking the trend of right angle, manicured modern design, we decided to go with organic shapes to soften the landscape and align with the natural shape of the plants. Have we waited long enough for this to come back into vogue? That has yet to be seen, but, of course, it’s a moot point since we’re designing the yard for ourselves (and then, ultimately, pollinators too!)
It’s worth noting that every pool designer was only offering rectilinear pool designs. In fact, our pool builder said he had not built a freeform pool in about a decade. Fortunately for us, TJ is a true landscape artist and provided a framework that we loved.
On the left side of the drawing is the North Side yard. As previously mentioned, this area was defined as a xeriscape with walkways, with a strong need for privacy in the east corner, and a requirement for water retention and control for roof runoff.
On the right side is the South Side yard, which was defined with oasis elements around the pool, a strong need for privacy at the south wall, and a requirement for water retention and control for roof runoff.
I added drip irrigation infrastructure in four zones:
South side yard
North side yard
North side along the house
Cacti and succulents
The final implementation of this plan varied from the foundation drawing, as is often the case with the best laid plans. Considerations affecting change included:
A 3 year plan for privacy, which required choosing faster growing plants at a higher density than shown in the drawing
Plant availability – I don’t have a landscape license so couldn’t buy wholesale, but did almost all of the purchasing and planting. Some plants called out in the drawing were not practical to procure and plant given the desired size or function.
Cost, of course. As anyone who has planned and completed large projects is likely aware, you can cost, labor and time, but not all three at once.

Welcome back! This is the second installment in this series – in the previous post I presented the history of the project and the design considerations for the South Side Yard – you can view that post here.
The side yard on the north side of the house has two separate microclimates. The area near the house gets sun in the summer, including late afternoon sun, but during the late fall until early spring, no sun hits the landscape because it’s shaded by the house. Selecting plants for this area can be a challenge, but with some judicious selections the summer sun can be moderated. This area will also be responsible for retaining and controlling water runoff from the roof.
Towards the block fence the sun exposure is more consistent, especially for taller shrubs and trees. The goal here is to have a xeriscape and walkways, similar in design to a botanical garden.
On the west end of the side yard there is a mild need for privacy screening, but a much stronger need for shade since the late afternoon summer sun comes blazing over the front gate. You can almost feel the heat radiating from the dirt in this early afternoon picture. So we’ll be using trees and shrubs to create some microclimates for plants and people.
The east end of the side yard has two large 2-story homes, both with second story balconies, so privacy is a big consideration. Screening will be accomplished with trees and shrubs.
Landscaping a bare earth tract home backyard into a taste of paradise, then evolving it to support pollinators and the web of characters that support an ecosystem. This is the first of a series of posts to share the story of discovery and a labor of love.
It’s 2019, and after 9 months of searching for a resale home, we ended up purchasing a new tract home further out than we wanted, but availability and price aligned to a relative sweet spot, and we made the leap.
(A View from the Rearview Mirror: A great bit of luck, that leap. Who knew a pandemic was on the horizon, and home prices would begin to see upward price pressure that was unimaginable. In fact, when the pandemic first hit, the developer began discounting homes due to lack of demand.)
We had just moved to Phoenix from the midwest and I had taken some landscape classes at the Desert Botanical Garden to learn about plant selection, irrigation and water conservation, so this project would put the newfound knowledge to good use.
I wasn’t, however, yet aware of the importance of native plants to support pollinators in the yard. So the foundational landscape that we designed and planted was focused on a botanical garden style xeriscape with oasis elements. Tuning the landscape for pollinators came later, after the pandemic hit and I became involved with the MetroPhoenix EcoFlora iNaturalist project (more on that later) and the Maricopa Native Seed Library.
South Side Yard Design
A blank slate can be daunting, as shown above in our initial “scorched earth” yard. This side yard faces slightly off from 180 degrees south, so it gets lots of winter sun. Because of the way the sun travels, however, it also gets late afternoon summer sun, which is the hardest on plants.
A two story home with a second story balcony, and a next door home that’s close to the fence, guided us to design for privacy along the fence line. Another design element would be a pool to make the summers more enjoyable and to add an oasis in the desert aesthetic. We also wanted walking paths to give the yard a botanical garden feel.
And of course, water conservation is a necessary and practical aspect of the design. To efficiently deliver water to the plants I decided to use multiple zones of drip irrigation, and since rain water (hopefully the monsoons will return in 2022!) is the best hydrator for plants, the design will incorporate swales to retain water shed from the roof, which drains along the wall with the A/C unit.
Over recent decades, the plight of wild bees and other pollinators has gone from a niche area to one of the most mainstream environmental topics. Scientific research interest, capacity and consequently publications have grown tremendously in recent years, as has mainstream media coverage. The public has been engaged in a variety of ways to “save the bees” including through community science, policy consultation, planting of pollinator gardens and other widespread initiatives and campaigns … ‘Bee washing’, a term coined by MacIvor and Packer (2015), refers to items or actions claiming to support declining bee populations, and thus claiming to be pro-environment, without due diligence or scientific support … The crux of the matter is that when conservation actions are misplaced, as in the case with bee washing, they can actively harm populations meant to be conserved, waste limited resources (e.g. time, energy, money), misinform the public and/or de-legitimize scientific evidence.
Excerpts from Colla, S. R. (2022). The potential consequences of ‘bee washing’ on wild bee health and conservation.
In order to better protect wild bee health and biodiversity, conservation actions and policy will have to shift away from bee washing to more evidence-based, nuanced and precautionary approaches. Efforts should focus on reducing the reliance of systems on managed bees and reducing the impacts of managed bee use on wild bees. This will require policy which acknowledges and values the importance of wild bee health biodiversity for pollination services for crop plants and for resilience under climate change. Critical actions to protect wild bee health includes screening and monitoring of pathogens among commercial stock and in adjacent wild populations.

I joined iNaturalist in April 2021 to participate in the City Nature Challenge – 2022 edition is coming up soon! – and I had no idea at the time that it would be my go-to resource for appreciating and documenting the visitors in my pollinator garden. I was quickly drawn in by the many friendly and knowledgeable users and the potential to improve my understanding of the natural world. One year later, I’m delighted to reminisce and share highlights from my edible garden and native plant xeriscape. It has been a blast watching, photographing, and learning to identify hundreds of species of plants and animals. Please, join me for a celebration of diversity in my New Mexico neighborhood.
My journey to hosting a pollinator garden in Albuquerque began with an all but blank slate. The front yard was a sea of bare gravel plus cheatgrass, tumbleweeds, and goatheads, while the back featured 8 Russian olive trees and plenty of dandelions. In 2020, I decided to transform the landscaping and hired a local company to cut down the invasive trees. In their places, I planted Peach and Apple trees for fruit, Utah serviceberry (Amelanchier utahensis) and New Mexico olive (Forestiera pubescens) to feed songbirds, and Bigtooth maple (Acer grandidentatum) for shade and fall color. Thanks to the New Mexico Native Plants Society, Plants of the Southwest, Osuna Nursery, Hilltop Landscaping, the American Penstemon Society, and the ABQ Backyard Refuge Program, I found plenty of resources and support to select appropriate, drought-tolerant plants for my yard and begin to create habitat for wildlife.
Watching the Grass Grow
At the beginning of the project, I typically saw common city birds, lizards, bumblebees, rock squirrels, paper wasps, and not much else. It takes a while for new plants to get established and for neighborhood critters to (re)discover my yard. It’s all worth it now for moments like watching an American Robin eat serviceberries, a longhorn bee sleeping on a sunflower, or munching on a fresh apple that I grew.
When I started, I was familiar with common pollinators, like honeybees and hummingbirds, but there were so many branches of the Animal kingdom of which I wasn’t aware. (I’m doing a little better now and I hope you’ll scroll through some of our visual guides Insects – Pollinator Web.) By slowing down and observing with purpose, I find something new in the garden almost every day. It is both fun and frustrating to follow a little bee on her journey to collect pollen as I struggle to get clear pictures for identification.
By The Numbers
Honestly, I have been blown away by the diversity that can exist in 0.2-acres of land. We tend to think of deserts as arid and empty; in reality, Arizona and New Mexico combined have over 1,000 species of native bees plus more than 300 species of butterflies! I have recorded more than 600 yard species in the last 12 months, using iNaturalist. They include:
>100 species of cultivated plants, including 20 varieties of native trees and shrubs
59 butterflies and moths
50 ‘true bugs’ (Hemiptera)
47 volunteer plant species (“weeds” and wildflowers introduced by wind or animals)
12 crickets, grasshoppers, and katydids
New Mexico Whiptails and Southwestern Fence lizards
Flame Skimmer and Blue-fronted Dancer (dragonflies)
Imagine what we can do working together in our communities by planting yards full of flowers, instead of spraying chemicals and mowing lawns.
Every square inch of planet earth has ecological significance, even where we live, work, and play. If we landscape these areas with plant function as well as aesthetics in mind, we can create viable habitat where humans are, not just where humans are not … Today’s environmental challenges are so enormous that it is easy to feel helpless, as if one person can’t make a difference – despite the cliché that suggests you can. In this case, however, the cliché is right on: by choosing ecologically-effective plants for your landscape, by shrinking your lawn, and by removing your invasive ornamentals – all actions a single person can take – you will be able to make a difference that you can see, and enjoy, almost immediately. Life will return to your property!
It’s larval food plants are mostly oak trees and some Manzanita species in Arizona and Mexico. The caterpillar is small and hairy like adults and it would be really cool to find one in the wild, so please let us know if you see any!
This is the third post in a semi-regular series of interesting, colorful, and unique moths of Arizona and New Mexico. Today, I’d like to introduce you to yucca moths.
Yucca moths are in the Family Prodoxidae and found across the USA and Mexico. They are a spring and summer moth, timing their flights with blooms of different plants in the Agave family (Asparagaceae). Prodoxus coloradensisis found from southern California to West Texas and north along the front range of Colorado. It’s black stripes are a bold contrast to many plain, white yucca moth species.
Like all desert blooms, Joshua trees depend on just the perfect conditions: well-timed rains, and for the Joshua tree, a crisp winter freeze. Researchers believe that freezing temperatures may damage the growing end of a branch and stimulate flowering, followed by branching. You may notice some Joshua trees grow like straight stalks; these trees have never bloomed—which is why they are branchless! In addition to ideal weather, the pollination of flowers requires a visit from the yucca moth. The moth collects pollen while laying her eggs inside the flower ovary. As seeds develop and mature, the eggs hatch into larvae, which feed on the seeds. The tree relies on the moth for pollination and the moth relies on the tree for a few seeds for her young—a happy symbiosis.
This is the second post in a semi-regular series of interesting, colorful, and unique moths of Arizona and New Mexico. Today’s inspiration comes from a brief encounter last Friday. I was at an orchard and a White-lined sphinx moth (Hyles lineata), was getting nectar from plum flowers mid-afternoon.
These strong fliers are members of Family Sphingidae – the sphinx, hawk, and hummingbird moths. They are active at dusk (occasionally daytime) and can hover like hummingbirds instead of landing on flowers.
This insect has a wide host range. Some of the plants utilized as host plants in the Midwest include apple, evening primrose (Oenothera spp.), four-o’clocks (the common annual Mirabilis jalapa and wild four-o’clock, M. nyctaginea), fuchsia, Gaura lindheimeri, grape, pentas, purslane, tomato, and willow-weed (Epilobium). Other native plants are used elsewhere, such as sand verbena (Abronia umbellate), wishbone plant (Mirabilis californica and other species of Mirabilis), and brown-eyed evening primrose (Camissonia claviformis ssp. piersonii) in the desert Southwest and toothed spurge (Euphorbia dentate) in Texas.
This is the first post in a new, semi-regular series of interesting, colorful, and unique moths of Arizona and New Mexico. The first post is inspired by Ronald Parry’s talk I saw on Zoom last week (recording here on Youtube). In the USA, the label “moths” represent over 90% of all Lepidoptera species, but butterflies get most of the attention. We can save the Monarchs and appreciate/support their overlooked “cousins” too!
Dalcerides ingenita (no common name yet) is the only species in the moth family Dalceridae that makes it north of the USA-Mexico border. The caterpillars are covered in a gelatinous material to deter parasites and predators. The larval host plants are manzanita and native Emory’s and Blue oaks.
March 13, 2022. New Mexico’s state insect, the Sandia Hairstreak butterfly, is flying again in the foothills of the Sandia Mountains in Albuquerque.
Range. Callophrys mcfarlandi was discovered in New Mexico, a state that still encompasses nearly all of its US range. It also occurs in West Texas and south into Mexico.
Life History. Larvae have a very restricted diet, eating only flowers and developing seeds of Texas and Woodland beargrass (Nolina texana and Nolina greenei). The similar Nolina microcarpa is widespread in New Mexico and Arizona, but it blooms in late in summer, which apparently is a deal-killer.
Left: old flower stalk of Nolina greenei; Right: hillside teeming with Beargrass
The host Beargrass species are not easy to find at nurseries, but this plant grows easily from seed. I bought seed from alplains.com and they germinated indoors before I transplanted outside in very sunny spots. Another option is to sustainably collect a small number of seeds from wild plants you encounter. They are ripe by mid-summer when the color is coppery. (Warning, they grow slowly, like related Agaves and Yuccas.)
