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.

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.

Pruning tips for honeysuckle vines:  Prune your plant in later winter when it is dormant.  With pruning shears, remove dead blooms from your honeysuckle as soon as you see them.

Our garden has become a very busy place.  It is October in the Arizona desert and our honeysuckles are still blooming.  What a joy to sit quietly and watch the butterflies and hummingbirds feast on the bright tubular flowers.

These heat tolerant honeysuckle plants did well even in full desert sun as long as they received their daily water.

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.

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.

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.

There are over 100 species of Mandevilla plants.  The blooms start out as a lighter color and get darker as they age.
