Pomegranate is #1 in our TOP 10 Heat Resistant Plants!

The bountiful pomegranate tree is native to the Mediterranean region which has similar growing conditions as the Arizona Sonoran Desert.  Pomegranates thrive in the drier climates of California and Arizona.  As a matter of fact, in 2009 the first commercial pomegranate farm started in Arizona. This fruit tree seems satisfied with our alkaline soil and experiences no deficiencies!

Although the pomegranate originated in Iran, ancient records show it is one of the oldest known cultivated fruits.  Biblical Archaeologists discovered fruit such as the pomegranate,  was much more than a food; it had symbolic significance for the Ancient Israelites.  The antiquated Greeks believed pomegranate juice was the “symbol of love”.  The botanical name for pomegranate is Punica granatum belonging to the family Lythraceae. P. granatum has more than 500 cultivars.  In 1769, the pomegranate was introduced into California by Spanish Settlers.

In the sizzling, sunniest area of our yard we now have five pomegranate trees, shrubs ranging from six months to six years old.  “Wonderful” is our cultivar and is also the most common cultivar for Arizona.  Recently,  we had record temperatures of 113 degrees F; with higher temps forecasted for next week.  There was some vexing over the younger plants, but it proved to be unnecessary.  We are delighted to report our Punica granatum flourished in the extreme desert heat!

The adamant pomegranate is drought tolerant and does best with well-drained soil, semi-arid climates and plant hardiness zones 8 to 10.  The fruit is adversely affected in wetter climates along with the plant becoming prone to root decay.  Tolerant to frost down to 20 degrees F.  Easy to grow, this deciduous tree can mature to 30 feet; but it is more common to see pomegranates at 12 – 15 feet.

The leaves of Punica granatum are glossy, narrow, lance-shaped and deer resistant.  The lavish flowers are bright orange-red with a fleshy tubular calyx.  Some cultivars are grown for their flowers alone and used as ornamental trees.

Pomegranate fruit is a berry filled with seeds numbering 200 to 1,400.  The seeds are in a white, spongy, acidic membrane.  The outer skin is a tough , leathery texture.

HARVEST:

The fruit is ripe when it reaches its distinctive color and it makes a metallic sound when tapped.  Overripe fruit will begin to crack and the seeds will become harder.

EATING:

The easiest way to eat a p. granatum is to use a bowl of water to separate the seeds.  The seeds sink and the white membrane floats.

Slice the fruit in half and then hold it upside down and beat gently with a wooden spoon so the seeds drop down in the water.

Purple, Yellow, and Red Lantana are some of the best drought resistant plants

Lantana is the best heat resistant plant that can add a punch of color to any flower bed. Lantana flowers come in a variety of orange, white, pink, yellow, purple, red and bi-color options.

These hardy plants are native to tropical regions of Africa and here in the Americas.  Lantana is a genus of about 150 species of perennial flowering plants in the VERBENA family, Verbenaceae.

Depending on where you live and the type grown, Lantana plants can be treated as annuals or perennials.

Verbena, Lantana, requires heat to do well, so plant them where they will get plenty of sunWell-drained soil is a must, as Lantana won’t tolerate wet roots.

When should I water my Lantana, Verbena plants?  On average the ground Lantana need a good soaking twice a week. A good indicator is the leaves.

Lantana growing in containers may need to be watered more depending on the temperature.

Very hardy Gold Lantana is great for borders

If your Lantana is wilting, then water it but try not to get water on the leaves.  The sun can burn Lantana leaves that have water on them.

The stems of your Lantana are HOLLOW so overwatering will cause your Lantana roots to rot.

Mandevilla on a Trellis – Arizona Desert Garden

The MANDEVILLA vine is growing well.  This Mandevilla plant is native to Central and South America – named after Henry Mandeville (1773-1861), a British diplomat and gardener.

Mandevilla, also known as Brazilian jasmineDipladenia,  is a flowering tropical plant that originated in the hills above Rio de Janeiro.

Mandevillas develop spectacular flowers in warm climates. They are perfect here in the hot desert Arizona garden. One of our secrets for cultivating this luscious pink variety (they come in white, red and yellow) is the part shade design.

**We purchased the 4 trellises from Home Depot, bent them slightly to fit the arch and then screwed them together.

An important part of Mandevilla care is the light it receives. The Mandevilla vines need some shade. We used 4 large plastic garden trellises by the front door as you can see in the photo. Mandevilla plants love bright indirect or filtered sunlight, but will get burned in full sun especially this Arizona sun.

Mandevillas are a vine and will need some type of support, we used garden ties and tape to help train it along the trellis.

Some say the Mandevilla Vine is not a Perennial plant because it will NOT survive if temperatures reach below 50 degrees.  BUT this past winter Southern Arizona reached down to the 30’s and as you can see this beautiful plant is thriving and full of pink flowers. Mandevillas have brought tropical flair to our Arizona front yard and desert garden.

LANTANA made #2 for the top 10 heat resistant plants in Arizona

Lantana plants and shrubs are one of our favorites for our desert garden and front yard.  I recommend this flowering plant to people who want color in their landscaping. Not only is our Arizona Lantana perennial but it is also a low maintenance plant and easy to grow.

In some cooler locations Lantana plants are annual; but places that do NOT get freezing weather will have new colorful blooms every spring.

Lantana seems to have no problems surviving on little moisture and soaking up unyielding sun.  When watering your lantana try NOT to get the leaves wet but water at the base of the plant.  This will prevent the plant from being sun burned.

If I see the leaves wilting I water immediately, soaking the Lantana well to promote deeper, stronger roots.

Can you grow Lantana in pots and containers? Absolutely and lantana loves it!

We have potted lantana all over the yard.  It does take a little more effort to care for lantana in containers but it is worth it.

My potted Lantana seems to need more watering than my ground Lantana.

I do not let them dry out completely.  Some people do and it works fine for them but I choose not to.

When do I prune my Lantana?  Give your Lantana a good pruning in the spring to remove the old growth and prevent the extra woodiness.

Water and lightly fertilize newly trimmed Lantana plants and they will return to bloom quickly.  Lantana does not need much fertilizer.

a good pruning helps Lantana plants

When transplanting your Lantana, gently loosen the roots and shake off the excess dirt.  Old soil does not help your Lantana plants.

Place it in the hole you made and backfill with healthy topsoil.

Growing Lantana in pots is so easy.   Choose your size pot or container.  Then have a fun time deciding on your Lantana colors.  Stick to one or mix them up.

Remember to gently shake off the old dirt from the Lantana roots before you place it in its new home.    Potted plants need more watering especially in the hot sun.

Always water at the base of the plants and not the leaves.  An exception would be if the Lantana plant was not in direct sun.

Not only are Lantanas resistant to extreme temperatures but also drought tolerant.

Some of our Lantana shrubs are growing in unfenced areas and the desert animals leave the plants and Lantana flowers alone.

The woody stems on the Lantana plants are especially tough and durable and have been used for weaving.

What is the best way to propagate Lantana?   Dividing the roots in the winter when the Lantana plant is dormant is the easiest way to propagate.

Soaps, insecticides and common pest treatments can kill Lantana plants.  On the rare occasions that our Lantanas have pest problems, I give them a trim and all is well.

 

Canna Lily is my # 9 in the top Ten heat resistant plants

Our canna lilies were thriving during the intense heat that Tucson and southern Arizona experienced this summer.  Cannas are spectacular in our desert garden and I was thrilled it made the top 10 heat-resistant plants list.

We have several canna lilies that are growing in extra-large pots.  It is a joy to watch the leaves on this perennial plant shoot up and slowly unfurl into this tropical-looking foliage.

Canna lily heat resistant

Caring for a canna lily requires low maintenance and is quite easy.  Ours receives at least 6-8 hours of direct sunlight; which cannas prefer.  These lilies do well in large pots with good drainage.  When choosing a container, bigger is better!  This flowering plant does exceptional with some moisture so try not to let it dry out completely.

A canna lily is not actually a lily.  This exotic plant is related to the Ginger and Banana plants.  The flowers are beautiful but I have to admit my favorite part is the canna lily leaves.  The leaves are wide with a stripy pattern making cannas leaves the center of attention in our yard.

Order: Zingiberales, Family: Cannaceae, Genus: Canna

Infested cannas do not bloom, and generally look unhealthy.  Are bugs eating your canna lily leaves?  To address canna leaf rollers, cut off infested leaves or unroll leaves and destroy the caterpillar.  We spray bacillus thuringiensis, Bt, a few times a year when needed.  It is organic and easy to use if you follow the directions on the bottle.

To prune your canna lily simply cut the dead or damaged foliage at another leaf line to allow for new plant growth.

The rhizomes of Cannas are similar to potatoes but sweeter.  In South America they are grown for food.  Peel and cut the roots into chunks; place them in the oven and enjoy your delicious canna lilies.

If you live in climate, growing, zone 7 or warmer, your cannas can be grown outside year round.  In cooler climates the rhizome can be dug up and stored in a cool, damp environment.  Plant your canna lily in the spring by burying the rhizome 4-6 inches below the surface.

These over-sized gracious leaves and silky tall flowers make our front garden a tropical escape away from the arid Arizona desert.

BOUGAINVILLEA is #10 – in our TOP 10 Heat Resistant Plants

Bougainvillea are tropical plants that thrive in outdoor areas with low rainfall and intense heat.  The 100 degree temperatures do not faze our Bougainvillea.  This flowering jewel is number 10 on our list of the BEST heat-resistant plants in Arizona.

Bougainvillea
Bougainvillea magenta color

Bougainvilleas are native to South America; therefore, it is drought resistant (instead of “drought tolerant”) because it is not a desert native plant.  Caring for and growing a Bougainvillea takes more effort but it is worth it!

drought tolerant desert shrubs
Bougainvillea bushes and vines in Arizona

Bougainvilleas flourish in pots and containers.  To grow this striking ornamental vine choose a very sunny place. Be sure your pots have holes in the bottom; adequate drainage is a must! Bougainvillea growing tip: Fertilize with Hibiscus Food.  Hibiscus food has more potash than many other fertilizers. Be sure to measure exactly the amount of food according to the size of your pot.

The amount of watering for your Bougainvillea is directly related to your area and the local weather. There are some basics —- Bougainvillea is a drought resistant plant, and requires very little water once established.  Be sure to let the soil dry between waterings; if your Bougainvillea’s roots stay continuously wet it will promote a weak and shallow root system. Wilting is the best indicator that watering is needed.  Don’t let it dry out completely as this will cause bracts and foliage to drop.

When choosing an area to plant your bougainvillea, remember that higher ground is best – as this makes water drain AWAY from the roots. Avoid overwatering.

drought and heat resistant desert plant
Bougainvillea in full bloom

In Florida, landscape professionals commonly perform a hard cut at the first sign of summer, and keep on a regular trimming schedule all summer long to maintain size of the Bougainvillea.  Pinching is the method of removing the soft tips of young plant stems to encourage fuller growth.  Bougainvilleas will send out several new stems just below the pinched tip.

The more regularly you pinch, the more your bougainvillea will branch and bloom.  The best time to prune or pinch is after the flush of color or flowering cycle is completed.  Flowering cycles are typically four to six weeks. Lets get pinching!
