Petunias: Hardy Outdoor Flowers

Petunias are one of the most popular annual flowers for sunny gardens. I live in a colder climate with four seasons, and the petunia is considered a summer annual in my region. They endure for the entire summer season, blooming continuously until well into the autumn.

These colorful flowers are an easy plant to look after. Petunias are not only a pretty and popular outdoor flower but they are also very hardy. I certainly found this out through first-hand experience one summer when I planted a few petunias among other varieties of annual flowers. The other varieties soon died off, but the petunia kept blooming throughout the summer and into the autumn without fail!

A Bed of Petunias

Planting a variety of petunias in all different colors is all you really need for an attractive bed. It is much easier to take care of one variety (especially a hardy one!) because your entire flower bed will have the same basic requirements and will flourish together under consistent care. A display of one color variety of petunia also creates a very striking display as we can see in the picture below.

The Unstoppable Petunia

The petunia is the ultimate survivor. This flower is originally from warm and sunny Argentina but it has made its way into colder climates.

The petunia soon became a favorite summer time annual because the blossoms come in a wide range of colors such as white, purple and pink. There are also varieties that are variegated or striped in color. The bloom sizes range from quite large to somewhat small.

The petunias we know today are hybrids that are mixtures between petunias and other flowering plants. These hybrids have been cultivated to provide certain desirable characteristics such as a low growing, mounding or heat tolerant.

1. "Kandy Kane"

Red and White Stripe

It looks like a little bit of Christmas in the summer thus this gorgeous petunia certainly earns its name. It has beautifully defined red and white stripes that make this outdoor flower a show stopper. This variety enjoys full sun but will tolerate some shade. It will grow 30 cm high and 15 cm wide or 12 inches high and 6 inches wide. Perfect for anywhere - beds, pots, hanging baskets - very versatile.

2. "Dreams Pink"

Pretty in Pink

This pink performer has a mounding, tight habit so you will get an abundance of blooms close together. The color is a very deep pink that is very striking to look at. It grows about 25 to 38 cm high and grows to a width of up to 30 cm. This variety prefers the sun similar to most petunias.

3. "Purple Vein Ray"

Purple People Pleaser

These purple and white petunias have large flowers with striking dark purple veins. This variety is quite tolerant of the heat and will look great even during the hottest days of summer. It will grow 15 to 25 cm or 6 - 10 inches high and 20 to 30 cm or 8 - 12 inches wide. This petunia is a real beauty.

4. "Purple Wave"

Low-Growing Wave of Beauty

This plant produces 3" flowers with a low growing habit that is perfect as a ground cover for the border of flower beds. These spreading plants are great for hanging baskets as well because they will drape quite elegantly over the sides. These petunias will reach a height of 10 - 15 cm (4 - 6 inches) and spread up to 150 cm (5 feet).

5. Classic White

White Blooms of Beauty

The classic look of an all white display or as a perfect accent to other colours - these petunias get the job done! They have a mounding habit and with 3 inch blooms they will create quite a show. They grow about 25 - 38 cm (10 - 15 inches) high and about 25 - 30 cm (10 - 12 inches) wide.

Fun Fact!

Did you know that Dixon, Illinois is the Petunia Capital of America. Each year they hold a Petunia Festival that lasts for a week in early July.

My Petunias

My decision for this summer is to plant a flower bed exclusively made up of petunia flowers. Why? Here is my petunia story...

Last Summer

The above picture was taken of my flower bed one summer. You can see several petunias in bloom and yes, I know they don't look too spectacular. In fact, they look quite the opposite and there is a reason for this so here is what happened.....

How to have Abundant Flowers

I was once an avid flower bed gardener. Those were the days when I was home raising my family and didn't have a job that took me away from home for eight or more hours per day.

Every year during that time I had a large display of a variety of flowers throughout the summer. I would plant flowers of all types and they flourished under my care. I was very diligent with watering and plucking off dead blooms and I fertilized them regularly. Needless to say I was very proud of my flower garden.

All this work created a very beautiful, abundant and colorful display year after year. Neighbors would ask me how I did it and I shared my "secrets" with them. However, they are not really secrets! You just pay attention to the garden with regular maintenance - water, deadhead, fertilize. It's as easy as that. I also made sure that the bed itself was dug up and new black soil was added each year before planting.

The Neglected Garden

Eventually, I went back to work outside the home and my flower garden suffered. I did not have the time and I found I lacked the motivation to keep the garden blooming. There were years I planted nothing and the bushes and perennials just filled in the blanks. Soon the perennials died off from neglect.

One year I was reminiscing about my garden of yesterday so I decided to buy a load of annuals from the garden center. I planted them around my front walkway. I soon found out, however, that bad habits die hard and I began once again to neglect the plants!

The Powerful Petunia

I must confess that I totally neglected them. They were left to fend for themselves and make do with just sun, rain and whatever nature provided. The plants slowly died off EXCEPT for the petunias! The petunias grew and blossomed. No, they were not full and abundant because I had only planted a small number of them but that few started to branch out and fill in the blanks.

So the picture tells the story. You can even see some of the "skeletal remains" of the other plant varieties.

I made a mental note to myself - buy only petunias next year!

        I used to have lots of petunias hanging from my balcony but then we decided to turn the balcony into the room and join it to the rest of the closed space so no more petunia for me. As if living in a flat is not boring as it is :) So I get a huge basket of petunias and hang it on my patio shade construction during the entire summer when I get to enjoy our summer house. Dark purple petunias are my favorite.
