Red Salvia is # 3 – in the top Ten Heat Resistant plants for the Arizona garden

Multitudes of people love Salvia.  These Salvia plants, better known as Sage or SCARLET sage, are indigenous to nearly all continents.

Most varieties of Salvia are heat resistant and drought tolerant along with providing colorful flowers that bloom lavishly.

This plant is easy to grow and Salvias furnish over 900 species; offering amazing potential for your garden!  The lush green leaves of the Salvia plant are so attractive that this Sage looks handsome even when not in bloom.

Salvia is a member of the Lamiaceae or Labiatae family; the MINT family.  Hot temperatures are a considerable concern for our Arizona gardens and Red Salvia loves the heat!

Salvia splendens, Salvia coccinea, Salvia darcyi, Red Salvia, or commonly referred to as Scarlet Sage are hardy, impressive plants and our favorite choice because of their lovely red blooms.   These Red Salvia are not edible like the sage in your kitchen.

Like most Salvia, the fragrant foliage is deer and small critter-resistant.  One of our Scarlet Sage, RED SALVIA, gardens is growing in the open desert and available to all wildlife.  In the past several years, we can report that our desert sage was devoured 1 time by JAVELINA but has been left alone ever since.  Most likely the Salvia made them ill.

A location with full sun is the best choice for most salvia varieties but some are shade tolerant.  Our Salvia located in part shade did not make it through the winter; on the other hand, the salvia plants in sunny locations come back year after year.

When the flowers are spent the Salvia will self-sow its seeds! Take a look at the photo below. No worries about Salvia being intrusive:  you can easily transplant the seedlings or share them with friends.  Simply pull up your unwanted plants.

Sometimes called Autumn Sage, Red Salvia blooms continually from spring through fall. A garden plant “must have” that is perennial and hardy in Tucson and Phoenix.

Can you grow Salvia in pots and containers?  Absolutely! We have several different pots with gorgeous Scarlet Sage blooming throughout the yard.  Our favorite color of Salvia for our garden is red but many cultivars offer pastel blooms such as pinks and blues.

The main difference with growing Salvia in containers is:  1)  the plants need to be watered more often      2)  several of the small shrubs needed replaced after winter

The abundant showy flowers produce a good amount of nectar making them attractive to hummingbirds and some people have named salvia: HUMMINGBIRD SAGE.

Goldfinches and other birds visit the Salvia plant to pick out the tiny brown seeds hidden in the calyces.

Deadheading Salvia encourages more blooms and more birds!  It can be so fun watching the Goldfinches pick out the seeds.  Salvia plants can get pretty tall and unshapely.  Prune the salvia stalks back for fresh growth and new blooms!  We trim often to keep a fuller shrub and nice shape.

Hardy Salvia has been a jewel in our garden and definitely worth a try. 🙂

Philodendron made # 6 in my top Ten Heat Resistant plants for Arizona

Philodendrons are native to the tropical Americas and are a rain forest plant.  With close to 1,000 species of philodendrons you have many choices of the best foliage plants available today.  Heat resistant, oh yes!  Philodendrons do amazing in southern Arizona even with temperatures reaching over 110 degrees.

One of the best houseplants that adds a delight to any room is the philodendron.  You can choose from a climbing or non-climbing variety.  Our Elephant Ear, philodendron bipinnatifidums, are growing in pots and containers but in the spring I will be planting several in soil next to trees that have regular irrigation.  Philodendrons like water because they are a species of the rain forest.

The genus Philodendron is in the family Araceae with each species having its own leaf size, color or shape that gives it a unique personality.

Propagating from climbing philodendrons is quite easy.  Simply gather a stem cutting and place it in a glass of water.

In the rain forest, most Philodendron species live on the trunks or branches of trees and do not need soil to survive.  Those tree-dwelling species are known as epiphytes or hemiepiphytes and are plants that live upon another plant.

What is an epiphyte?  This type of plant begins as a seed placed on branches by a rain forest animal and grows attached to the host tree.  A hemi-epiphyte is a seed that was dropped on the ground, begins to grow and then finds a host tree to climb.  A simple example would be if the seed came from a bird’s droppings…

The Tree Philodendrons are found largely in Brazil, Argentina, Bolivia and Paraguay.

Try not to plant your philodendrons in too large of a container.  They actually grow better when their roots are slightly cramped.  Re-pot your philodendron when the roots begin to compact into a ball.

Philodendron bipinnatifidum, Elephant Ear philodendron, does produce flowers but it can take more than 10 years…  Flowers are rarely produced on philodendrons that are grown indoors.

To keep your philodendron clean; mist the leaves every few days.  Misting is another way to make this tropical plant feel like it is in the jungle.

The leaves on my philodendron bipinnatifidum started turning yellow and brown.  Originally, I placed this plant in too much direct sunlight.  After trimming the yellowing leaves the philodendron was moved to a partly shaded area where it could not be burned by our Arizona sun.

I can safely say this philodendron plant has no insect problems.  If you are looking for a low maintenance plant that has large green leaves and gives a tropical feel to your garden… Elephant Ear philodendrons may be the right choice for you.

Red Geraniums made # 7 in my top Ten Heat Resistant plants for southern Arizona

Zonal geraniums can last for years with the right growing conditions.  The red geraniums pictured in this article are the first plant my husband and I acquired when we were married.    They are very unique and add a velvety, radiant color to our desert garden even with the record-breaking 2012 temperatures.

This red flower is called a zonal geranium.  What is a zonal geranium?  Zonal geraniums are the genus Pelargoniums, and are NOT true geraniums. This species of flowering plants work well in Arizona and Texas because they are drought resistant, perennial and heat tolerant.  Zonal geraniums originated from South Africa and have become very popular as bedding and container plants.

Important fact:  Geraniums, Pelargoniums, are poisonous to dogs and cats.  If your pet eats a geranium contact your local veterinarian right away.

I’m always on the lookout for a plant that adds a softness to a thorny, spiky desert garden.  Amazingly, a red geranium can thrive almost as well as a cactus.  We have several throughout our Arizona yard that are either in full sun or sparse shade.  All of our zonal geraniums are doing well; but, the ones with semi shade have larger leaves and more flowers.

Caring for geraniums is easy:

  • They love the sun but do well in sparse shade especially with high temperatures
  • Plant Pelargoniums when there is no danger of frost, they do not like the cold
  • In the fall plants may be dug up and brought indoors by a sunny window away from your dogs and cats
  • Water geraniums when the top 2 inches of the soil feels dry
  • Zonal geraniums are critter proof and virtually insect free 🙂

Pelargoniums are low-maintenance and a great choice for xeriscape yards.  Grow your geraniums from seed or plant cuttings.

If your geranium has yellow or red leaves it is experiencing stress in some way.  The most common causes of red or yellow leaves are:

  1. your geranium – pelargonium is over-watered
  2. phosphorus deficiencies, are you fertilizing?  If it has gotten cooler at night and the temperature drops below 55 your geranium will not be able to absorb trace minerals.
  3. another possibility is too much sun
  4. or planted too close together

Too diagnose the problem simply look at the exact conditions your plant is growing in.

Pelargonium is a zonal geranium

Even with the best of care a few leaves will inevitably turn yellow; simply remove them along with spent flowers.

In the fall temperatures drop and red leaves on pelargoniums are a sign that it is time to move indoors or to take cuttings from annual cultivars.

October is barely here and I’m already daydreaming about plans for a colorful, lush spring heat-resistant garden.
