Salvia darcyi, a hardy, heat resistant desert Garden Flower in a container!

RedSalvia darcyi,  survived well through the desert winter months that hit in the mid 30’s and does superb in the high heat as long as it is watered everyday! It is a thirsty plant during these temperatures of 100 degrees or more.  I recommend larger pots than the ones I used.

This is by far the MOST hardy, successful flower in my Arizona Garden! This perennial Salvia will generally grow from between eighteen inches and thirty-six inches, yet there are some that are much smaller. Mine is averaging about 20 -22 inches. The red salvia in the picture is a young plant that actually started from a fallen seed. The photo above is just after I pruned the finished red flowers. From having Salvia (red and blue) for over 2 years now I have learned it is best to trim them quite far down the stem to gain a thicker shrub.  Best of all this flowering plant is critter proof.  Last year the desert rats, squirrels, and rabbits ate most of our flowers except the Salvia. Since then, we are determined to have a rat-proof, squirrel-proof, rabbit-proof thriving Garden.  Quick note: Hummingbirds love the flowers and will visit your garden often!

To keep your Salvia looking vibrant and encourage better flowering, deadhead the plant. You can do this by pinching or cutting off the flower spikes with spent blooms, I like to use small pruning shears.

Honeysuckles made # 5 – in the top Ten Heat Resistant plants for Arizona

Honeysuckles love the Arizona heat and the hummingbirds love the honeysuckle.  Now that is a desert garden delight!

As long as I water this thirsty honeysuckle shrub it will produce abundant blooms most of the year.  The narrow, orange, tubular flowers give enthusiasm to the garden with their bright colors.

heat-resistant orange honeysuckle

Our orange honeysuckles are fast growing perennial plants that are low maintenance.  Care for your honeysuckle with regular watering and pruning to keep the growth under control. With 180 species of honeysuckles, genus Lonicera, you can pick from pink, yellow, white, orange, red, etc., flowers.  Honeysuckles belong to the Caprifoliacea family which includes all types of woody shrubs and fragrant vines.

When choosing a honeysuckle to grow, be sure to check the label as some varieties are hardier than others and can cope with frost.  Also, there exists a few species of honeysuckle that are considered invasive such as Japanese honeysuckle.

In the photo above is Lonicera arizonica which is a native Arizona Honeysuckle.  It is a perennial vine or shrub that you find in the open at elevations of 6,000 – 9,000 feet.  According to Northern Arizona University, this native honeysuckle was used by Native Americans to cleanse the bowels.  Navajo tribes used the leaves of the Lonicera arizonica  to induce vomiting.  Can I eat the red berries from the Arizona honeysuckle?  Yes you can eat the berries but it will have a purgative effect.

Growing Sunflowers in Pots – facts about sunflowers

The sunflower has a tall, thick stem crowned by what seems like a single giant flower. Interestingly, this flower is no flower at all;  but a constellation made up of hundreds of small flowers called the sunflower head!

Although the sunflower head resembles a huge flower with yellow petals and a brown center, it is actually the brown that is the constellation of flowers, with the yellow leaves acting more as a protectant to the sunflowers during the flowering and seed development phases.

The sunflower’s cheery facade plus its sheer height make it a wonderful plant that everybody will enjoy, either in the vegetable garden or at the back of a flower bed.

Sunflower in pots
Arizona Sunflower in a container

A sunflower can grow to become well over 10 feet (3 meters) tall and the head can become quite wide. Once open,  the sunflower head will start to follow the sun while it is moving across the sky.

species of sunflowers
Large Sunflower Head of “LEMON QUEEN” variety

The flowers in the center of the sunflower will then start to grow fruits, sunflower seeds, and after a while these seeds will loosen and scatter across the ground.

Once that is done, the life cycle is complete and it will eventually wilt and die so that the new seeds can grow to become sunflowers in the next growing season.

When growing sunflowers it is important to consider where you want to plant them because they will need full sun to mature successfully. Many people grow sunflowers close to walls since the sunflower can be quite sensitive to the wind;  but, planting close to a wall will unfortunately come at a loss.

sunflower with multiple buds, blooms

Sunflowers are sensitive to the amount of sunlight they obtain, and how much water required to optimize their growth.  Too much water may result in the soil loosening and becoming far too unstable to support the weight of the sunflower head as it sways in the wind.

SONJA sunflower variety

Planting a larger grouping of sunflowers has the benefit of helping to stabilize the immediate area of soil and helps to create some barrier to wind damage. I put stakes into the ground close to the sunflower stem making sure it stands strong and stable on its own. Next, you can tie small pieces of thick string,  florist ties or velcro around the stake and the sunflower, thus helping them to support each other.

sunflower in container
sunflowers in pots

Currently we have several sunflowers growing in large pots.  Sunflowers do not do well if they sit in water so it is important that your pot or garden container drains well. You can use a layer of sand or rocks in your container. The garden soil you choose needs to be full of nutrients.

When placing your sunflower seeds in a pot, do not put them close together. Depending on the size of your container, space them at the minimum of 3 inches apart.

Typically, sunflowers, Helianthius annuus, require absolutely no pruning at all.

sunflower seeds to harvest
sunflower seeds to harvest

To enjoy the seeds of your sunflowers here are simple harvesting tips:

  • When the backside of the sunflower head turns yellow be sure to protect them from birds, squirrels and other animals that eat sunflower seeds!
  • Once the back of the sunflower head is brown it means time to harvest!  Cut the head off about 12 inches down the stem
  • Then rub the head using your hand and the sunflower seeds will fall off

extra tidbit:  If pressed, sunflower seeds will give you sunflower oil. This oil can be used for many purposes and ongoing research is mapping new and improved uses every day. First of all, sunflower oil is great in cooking and will give food a very mild but distinct taste, similar to mild olive oils. Sunflower oil can also be transformed into lubricants for engine parts and can even work as a fuel for engines.

PROPAGATION:

Peat Pots are great and make growing and transplanting your Desert Bird of Paradise seedlings easy. Start your seeds indoors and when you are ready to plant simply put the entire pot in the ground. Roots will penetrate the peat pot and the pot disintegrates enriching the soil.

germinating seeds
dissolving pots for Bird of Paradise seeds

To germinate Bird of Paradise seeds,  soak the seeds from the bean pods (pods need to be brown) in water for 48-72 hours.  Next plant them in peat pots, barely cover the seeds.  You may prefer to use the paper towel method to germinate your seeds; if so, when a white shoot (root) appears, plant it with the white root DOWN. Cover the seeds lightly with damp soil.

The best time to see the Saguaro cactus bloom

The saguaro, Carnegiea gigantea, is the largest cactus in the United States and native to Arizona. In 1931 the opulent white blossom of the Saguaro Cactus was designated as Arizona’s state flower. The best time of year to see these cactus bloom is April through June.

large white flowers on the saguaro cactus

The Saguaro cacti mainly grow in the Sonoran Desert of Arizona.  When a Saguaro cactus reaches 35 years of age it begins to produce blossoms.  Amassed near the ends of the branches, the green buds bloom into milky-white flowers. The Saguaro flower blooms after sunset and last only one day.

At the top of the flower tube is a compact group of yellow stamens. The saguaro cactus has more stamen on its flower than any other cactus.  If conditions have been favorable for the Saguaro you could see hundreds of blossoms on a cactus.

Can I cut my yucca plant? Trimming your Yucca

Yucca is an evergreen, perennial plant with spine-tipped leaves that grow in a rosette around a thick central stem.  More than 25 species of Yucca live in the arid regions of the southwest.  One of the finest aspects of this desert plant is that it is low maintenance.

Tidbits:  The Apache Indians preferred the flowers of Yucca elata, a thin-leaf yucca, to those of the thick-leaf banana yucca. We know that  these flowers were eaten thousands of years ago because unusually large amounts of yucca pollen have been found in some dried human feces collected from Hinds Cave.

What is a Century Plant? Maguey – aka Agave Americana Plant

Maguey or Agave americana is a native plant from Mexico, but is now cultivated in many parts of the world. This drought tolerant plant, also known by the name century plant or American aloe, is neither an aloe nor a cactus, but pertains to the Agavaceae family.  The unique architectural Agave is one of the best xeriscape plants for your garden.

several species of Agave

poisonous Yellow Bird of Paradise shrub

Caesalpinia is a genus of flowering plants in the legume family, FABACEAE.  The fruit of these Bird of Paradise desert bushes is a long, flat seed pod.

The seed pods are toxic!  Watch small children and pets around these shrubs.

The level of toxicity for the bird of paradise plants is low.   The leaves contain hydrocyanic acid.  The toxins in the bean pods are tannins. The role of tannins in many species of plants is to protect it from predators.

Ingesting any part of  bird of paradise plants can cause gastrointestinal irritation. Nausea, diarrhea and vomiting are symptoms of bird of paradise poisoning.

Giant Saguaro desert cactus – facts and photos

Within Arizona’s Tucson Basin is The Saguaro National Park.  This park provides the ideal conditions for sustaining dense stands of the famous saguaro cactus.

**The most important factors for growth are water and temperature. If the elevation is too high, the cold weather and frost can kill the saguaro. Although the Sonoran Desert experiences both winter and summer rains, studies show that the Saguaro cactus obtains most of its moisture during the summer monsoon season.

Saguaro National Park
saguaro cactus in Arizona

There are dozens of varieties of cacti;  short, tall, stout, delicate but none quite as magnificent as the Giant Saguaro cactus.

Quick Saguaro Facts:

  1. Saguaros have one deep tap-root but most of this cactus’ roots are 4-6 inches deep and span out as far as the desert plant is tall.
  2. The saguaro is the largest cactus in the US.
  3. After the saguaro dies its woody ribs can be used to build roofs, fences, and parts of furniture.
  4. The Giant Saguaro can live to be 200 years old.

In the Sonoran desert the saguaro cactus has a boundless variety of towering and many armed shapes.

the saguaro cactus species in AZ

Water makes up 75 to 95 percent of the saguaro cactus’ weight.  During periods of drought the pleats of the saguaro cactus contract.  During Arizona rains the saguaro expands as it soaks up moisture.

saguaro cactus with fruit

Saguaros, like many desert cacti, grow excruciatingly slow.  Arizona cactus experts estimate that a forty-foot tall saguaro is about 150 years old.  Arm buds begin to appear when the saguaro is 75 years old.

Many saguaros now standing in cactus forests germinated in the mid-1800s.

saguaro cacti over 100 years old

To survive their early years, saguaro seedlings must be sheltered from the elements, whether it be under the canopy of other plants or in the crevices of rocky outcrops. Saguaro seeds can be deposited in droppings of birds roosting on branches of shrubs and trees.

nurse tree

Lightning, powerful winds, harsh winter freezes and the rotting of dead tissue kill saguaros.  The saguaro’s woody ribs stay on the desert floor until they are consumed by termites or decay and return to the soil.

The saguaro is not currently listed as threatened or endangered. Arizona has strict regulations about the harvesting, collection or destruction of the saguaro cactus.

Saguaro cactus can be found in southern Arizona and western Sonora, Mexico.

 

The Saguaro National Park

While traveling Arizona we stopped at Saguaro National Park, in Tucson.  The park is located in the Sonoran Desert.

The giant cacti, called Saguaros, are protected and preserved within the park.

The saguaro cactus in the Sonoran Desert

In 1931, The Saguaro’s Blossom became the Arizona State Flower.

The Saguaro Cactus blooms April through June. Its flowers are creamy white and numerous. Up to a hundred flowers can bloom on one Saguaro Cactus!

Saguaro Cactus Flowers
Saguaro Cactus fruits and blooms

The saguaro blossom opens after sunset and by the next afternoon the flower is wilted. The white cactus flower repeats itself night after night.   During the few hours the saguaro flower is open birds, bats, and  honeybees pollinate them.

saguaro red fruit

The Saguaro often begins life with a nurse tree or shrub which can provide shade and moisture for the germination of life. This Saguaro grows slowly — only about an inch a year — eventually becoming very tall;  reaching heights of 50 feet.  The largest saguaro cacti, with more than 5 arms, are approximately 200 years old.

 

The difference between drought tolerant and drought resistant plants?

Define drought tolerant.  What is a drought resistant plant? Here is the difference between drought tolerant (true desert plant) and drought resistant (originated in semi-arid places).

A flower or plant that has naturally evolved to survive periods of drought with little water and has the ability to tolerate substantial dehydration of their tissues and organs is drought tolerant.  Xerophytes are the BEST drought tolerant plants, shrubs, trees, and cacti.

cactus plants use little water are heat tolerant
Drought tolerant Saguaro Cactus and Prickly Pear Cactus

Cacti and many plants survive on little water and make Xeriscape not only essential but pleasing to the eye. Derived from the Greek word “xeros”, meaning “dry” and combined with landscape, xeriscape means gardening with less than average water.

drought resistant landscape yard
flowering, hairy cactus with drought tolerant agave plants

Many xerophyte plants have specialized tissues for storing water, as in the stems of cacti and the leaves of succulents. Others have thin, narrow leaves, or even spines, for minimizing water loss.  Xerophyte leaves often have abundant stomata to maximize gas exchange during periods in which water is available, and the stomata are recessed in depressions, which are covered with fine hairs to help trap moisture in the air.

drought resistant tolerant bushes in yard design
xeriscape yard with XEROMORPHIC plants like cactus, yucca, ocotillo

Drought tolerant plants have adapted by making use of either C4 Carbon Fixation or CAM (crassulacean acid metabolism) a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions.

xerophyte plants best drought resistant
A drought tolerant Joshua Tree and Yucca Cactus in this photo

In a plant using full CAM, the stomata, in the leaves, remain shut during the day to reduce the loss of water as vapor, but open at night to collect carbon dioxide (CO2). The CO2 is stored and then used during photosynthesis, which is the process of capturing the suns energy.

what is drought tolerant and resistant plants
Saguaro cactus and Palo Verde Tree are well – adapted drought tolerant plants.

CAM is particularly good for arid conditions because CO2 can be absorbed at night, allowing the pores on the leaves to stay closed during the day and thus reducing water loss. A easy way to explain it is drought tolerant plants can slow down metabolism.

Lovely Agave titanota BLUE variety

High elasticity of the cytoplasm and the capacity to withstand compression of the cells during dehydration are characteristic of drought-tolerant plants. What is cytoplasm? An easy definition of cytoplasm is a gel-like casing, covering – containing all the contents of the cell’s organisms, except the nucleus. Most metabolic (chemical reactions) pathways occur in the cytoplasm.

Ocotillo Cactus plant in the desert

Not to be confused with drought-tolerant plants, Drought Resistant plants are not true desert plants. Many have originated in semi-arid regions, the area around the Mediterranean, Latin America and sub-Sahara.

Here are pictures of drought resistant plants that are not native desert plants.

Plant your Bird of Paradise in full sun locations.  These bushes do fine in any well-drained soil including rocky, native soils.

In the Spring, prune to remove dead or damaged stems.  In the summer water your Yellow Bird of Paradise every week.  Water it deeply to stimulate a long taproot.  Once established the Yellow Bird of Paradise will need less water.

Asparagus Fern is my # 8 in the top Ten heat resistant plants

Introducing the dramatic Asparagus densiflorus.  Even when southern Arizona reaches temperatures above 100 degrees the asparagus fern thrives!  Our desert garden has a subtropical ambience thanks to the ornate asparagus fern. This customary name is somewhat deceiving because the asparagus fern is not a fern at all; but a member of the Liliaceae, or Lily family.

Growing these ferns in containers is easy and low maintenance.  This plant develops large tuberous roots and can become potbound in a relatively short period of time.  Asparagus Ferns are vigorous, fast growing plants that can take extreme heat as long as it receives regular watering.

To encourage new growth I give our asparagus ferns a trim every so often.  In the photo above you will notice several green berries that will turn red by winter.  Since these plants are dioecious, not all of your asparagus ferns will grow berries.

What does dioecious mean? Plants that are dioecious have their male and female parts on separate plants. Both male and female plants must be present for pollination to occur. Asparagus Ferns are toxic to cats and dogs.  Contact with the skin may cause dermatitis so I recommend wearing gloves.

From a distance, the asparagus fern, Asparagus densiflorus, looks very soft and delicate. This can be attributed to its fine, needle-like leaves.  Make no mistake, putting your hands into an asparagus fern will give you little scratches.

Asparagus Fern is native to South Africa and is an evergreen perennial that is commonly used as a groundcover or in hanging baskets for its showy foliage.

An easy way to propagate new Asparagus Ferns is by division.  Using a large serrated knife, you can easily divide up the root ball into half or quarter sections for more new plants.

The photo above is one of our potted asparagus ferns that is located in the full Arizona sun.  Other containers are nestled in part shade.  All of the plants are growing well with my only complaint being I need to plant more!

Yellow needles develop on asparagus ferns for different reasons such as rapid temperature change, under watering, over watering, spider mites and possibly a change in light.  Your asparagus fern will need less watering during winter and in low light conditions.

Asparagus ferns can be trained to grow as a vine or cascade down a hanging planter. Note:  Sprenger’s Asparagus has been declared a noxious weed in Florida, Hawaii and New Zealand.   Listed as a Class One Invasive by the Florida Exotic Pest Plant Council’s Pest Plant List (FLEPPC).

We love Asparagus Ferns and have grown them in hot, hot Arizona for years with no behavior problems.
