One of the most widely used flowers in Louisiana is the petunia. They can be planted in late winter or early spring for warm-season color or in the fall for cool-season color. In local garden centers, you can discover a variety of petunias, as you can with practically any bedding plants these days.
Plant petunias in late January through mid-March for greatest results, or from late September through early November. South Louisiana petunias perform well in the winter. The severity of our winter has a big impact on how well they perform.
Petunias are available in a variety of floral colors. Both single- and double-flowered petunias are available. In general, single-flower forms are more durable over time than double-flower forms.
The following are some “best management methods” to help you enjoy your petunias from now until late spring:
Make sure the garden bed is properly prepared to provide for adequate internal drainage and aeration.
How are petunias purchased?
Petunias should be purchased in compact, stocky plants. To encourage the plants to expand and take longer to mature into attractive plants, tall, spindly petunias will need to be clipped. Prior to planting petunias in the garden, harden them outside for a few days if you purchased plants from a greenhouse. Place the plants in a sheltered, shaded area at first, and gradually expose them to greater periods of direct sunlight.
Petunia ‘Phantom’
The petunia cultivar “Phantom” is particularly striking, with velvety black blossoms that mature to have yellow demarcations on each petal, giving them a starry look. The growth habit of this cultivar is erect and mounding.
Petunia ‘Rose Vein Velvet’
One of the greatest petunias to start from seed is reportedly “Rose Vein Velvet.” On trailing stems that can reach a length of 1m, multitudes of the pink, veined blooms are produced. An excellent cultivar for window boxes and hanging baskets.
Petunia ‘Black Satin’
The lavish petunia “Black Satin” has aubergine-colored flowers with a satiny finish. This small cultivar contrasts dramatically with light and vibrantly colored bedding plants.
Petunia ‘Bingo Red’
The Bingo line of compact, upright plants, which come in a variety of colors, includes the petunia variety known as “Bingo Red.” They are perfect for planting in little pots that may be scattered around because they are compact.
Petunia ‘Priscilla’
Petunia cultivars including “Priscilla” (shown), “Candy Floss,” and “Susanna” are part of the Tumbelina group. They feature larger, double, ruffled blooms than other trailing kinds.
Petunia ‘Cascadias Rim Magenta’
One of the Cascadia petunias, “Cascadias Rim Magenta,” is distinguished by its tendency to trail. They grow beautifully in window boxes and pots, or they can spill over the sides of hanging baskets. Other Cascadias petunias to grow include ‘Cascadias Indian Summer’ and ‘Cascadias Rim Violet’.
Colors available
Supertunias and Wave petunias come in a wide range of hues. Supertunias, the more varied of the two plant species, exhibit unusual flower color patterns.
While Supertunias may come in a hue called “raspberry blush,” which contains splotches of purple and scarlet in the same bloom, Wave petunia types mostly come in standard colors (red, white, blue, salmon, etc.).
Both Supertunias and Wave petunias provide excellent color possibilities overall. If you can’t locate a hue in one series of petunias, it’s frequently available in another.
Blooming
If you provide the right fertilizer and irrigation, Wave petunias and Supertunias will both grow for you all summer long.
Supertunias will typically bloom more aggressively, sometimes to the point where the plant’s green foliage is hardly noticeable. Wave petunias can also grow to produce a lot of blooms, but not as many.
Size of flowers
The blooms of the Wave petunia kind will be extremely similar to, if not exactly the same size as Supertunias.
While Tidal Wave and Easy Wave petunias have bigger blooms that are more equivalent to Supertunias’ blossoms, Shock Wave petunias will have smaller blooms.
Growing habits
The prolific spreaders known as wave petunias. For this reason, they are frequently utilized as a groundcover. Their long vines could become straggly if they aren’t routinely pruned back.
As far as 3–4 feet in some situations, some Supertunias, including those in the Supertunia Vista series, will spread similarly to how long a Wave petunia does. Supertunias will also significantly mound and can reach heights of 2 feet.
Fertilizer requirements
Supertunias and Wave petunias will both gain a lot from fertilization all summer long. Because of the quality of Supertunias, they might be a little more understanding if you neglect to fertilize or water them.
Do petunias reappear each year?
Garden petunias stop growing as soon as it gets below freezing (32 degrees Fahrenheit). Only the warmest regions of the United States can support them as perennials (USDA zones 10 and 11). Petunia x hybrida is an annual, thus most gardeners treat it as such and replace it every year.
Petunias in pots survive how long?
In response to your query, petunias can survive in warmer areas for two to three years. In frigid climes, petunias are actually annuals, despite popular belief. As a result, they might not be able to endure the bitterly cold winter weather.
Therefore, you must make sure they are out of the cold if you want your petunias to live for two to three years. The greatest strategy for accomplishing this is to keep them indoors.
All you need is a plan in order to accomplish this. You’ll need to put the petunias in a tiny container for this.
The ideal petunias for hanging baskets are which ones?
Two further popular varieties of petunias are Cascadia and Surfinia. These have a trailing habit, striking colors, and an abundance of flowers. Typically, they feature unusually colored broad flowers similar to regular petunias. These petunias have a lot of fascinating veining and shading. They spread or trail to a height of around 18 inches and are also simple to maintain. The window boxes and hanging baskets are the ideal places to plant these petunias.
What distinguishes a petunia from a wave petunia?
Wave petunias bloom extremely frequently and have a distinctive trailing growth habit. They are excellent summer performers and drape over the sides of containers and raised beds. A typical petunia grows erect or in a bush. While it might spread a little, it won’t fall as dramatically as a Wave petunia. An older hybrid than Waves, Cascade petunias are named after the Cascade mountain range rather than after how they grow. A shrub type petunia is called a cascade petunia.
What distinguishes petunias from Supertunias?
The Tidal WaveTM series of WaveTM petunias can grow up to 22 inches tall, however they were primarily developed to be used as ground covers when they were first launched in the early 1990s. They have the Tidal WaveTM, a large flower with higher plants, the Shock WaveTM, a little flower with vivid colors, and the Easy WaveTM, a spreading variant. The WaveTM Petunia is best utilized as a ground cover because it grows from seed and forms a large, dense root ball that could be difficult for baskets and containers. Long stemmed WaveTM petunias may become overgrown, have bare stems, delayed flowering, and need to be pruned back in the middle to end of the summer in order to promote new growth and flowers.
A more recent variety of petunias called Proven Winners Supertunias come in both single and double blooms with a vast array of colors. Cuttings rather than seeds are used to grow Petunia Supertunia. Supertunias do not produce seed because they do not originate from seeds. Because all of the energy is directed toward flower creation rather than seed production, the Proven Winners petunias are more floriferous. With the exception of Vistas petunias, which have a mounding habit and can grow to be 24 inches tall and 24-36 inches wide, Petunia Supertunia typically stand around 6- 10 inches tall and can spread/trail up to 24-36 inches. Supertunias have shorter stems than WaveTM Petunias, more leaves and flowers, and higher heat and humidity tolerance throughout the sweltering summer months. In comparison to WavesTM, Supertunia petunias are more suited for containers and hanging baskets since they do not produce a root ball that is as large and dense and will remain longer in the container. Additionally, Proven Winners petunias spill less in pots and baskets, making for a more attractive flower arrangement.
We offer a few watering and fertilizer suggestions to ensure that your flowers perform at their peak and endure far into the fall. We advise providing the appropriate amount of feed in addition to daily watering as needed for all annuals and potted plants. We advise feeding with a water-soluble fertilizer once a week while watering often during the hot summer months. Your plants could require a minor “haircut” to maintain their finest appearance during the summer. You could discover that hanging baskets only only a little trimming at the bottom of the pot. You could discover that shaving off a few inches from combination planters can give them a new look. I can’t stress this enough: treat your plants with the same respect you would do a living thing. A plant requires frequent feeding and watering much like a human being does to stay healthy.
The number of petunias in a 12 inch basket
You must strike a fine balance between wanting a stunning presentation and not crowding your plants. One plant per inch of basket diameter, or 12 plants, would fit in a 12-inch basket due to the restricted room for roots and supplies.
You might find that as few as 5–6 plants are plenty to fill the basket well if you opt for a larger trailing plant, like Surfinia Petunias, or decide to use a Grandiflora as the basket’s centerpiece.
Are all petunias contagious?
In conclusion, not every petunia is a “spreading” or ground-covering kind. Even though spreading or “Wave” petunias are only six inches tall, they can spread out swiftly and cover a sizable garden space in a single growing season. The blossoms will grow even larger with regular watering and fertilizer. As a result, it’s crucial to prune your plants properly and frequently to keep them healthy.
What hues of petunias match each other?
Sometimes a flowerbed does best with only one hue of bloom. It is possible to utilize a never-ending wave of petunia flowers and a monochromatic color scheme to assist produce an aesthetically pleasing result. All of the blooms don’t need to be the same shade of hue. Purple petunias, one of the most popular and plentiful hybrid petunia flower colors, can be used to achieve an eye-catching impact without taking away from the other plants in the garden. Plant petunias, for instance, with violet, vivid purple, and lavender-purple blossoms. To avoid being an eyesore, the color you choose should complement the rest of your landscape and blend in with it.
