The lavish petunia “Black Satin” has aubergine-colored flowers with a satiny finish.
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. “Cascadias Indian Summer” and “Cascadias Rim Violet” are two other Cascadia petunias to grow.
What distinguishes wave petunias from trailing petunias?
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.
Which petunia kind grows best in hanging baskets?
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.
How far apart should trailing petunias be planted?
All petunias require average, slightly acidic to neutral soil with a pH of 6.0 to 7.0 at a location with at least six hours of direct sunlight each day and more, if possible. Peat moss, aged manure, or compost should be added to the soil at a depth of 2 to 3 inches and then thoroughly worked into the soil until it reaches a depth of 8 to 10 inches.
According to the Old Farmer’s Almanac, the area should also have good drainage because petunias thrive badly in too-wet soil. While multifloras only require a spacing of 4 to 6 inches, grandifloras and multifloras both require planting at a distance of 12 inches. Petunias that spread or trail should be planted at least 1 1/2 feet apart, even if they only reach a height of 6 inches.
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 all petunias trail behind them?
Due of its vibrant color and durable blossoms, petunias are a fixture in gardens. 600 to 1,000 new kinds are created each year. Petunias come in two basic varieties: upright and trailing. The distinction is that upright petunias can grow as tall as 12 inches. Even though they only grow to a height of 4 to 6 inches, trailing petunias can extend 2 to 3 feet. Although spreading petunias, climbing petunias, and trailing petunias are all used interchangeably, respectively. Hybrids including Wave, Surfina, and Kirin have been known as trailing petunias thanks to marketing campaigns.

- The distinction is that upright petunias can grow as tall as 12 inches.
You can either start trailing petunias from seed or purchase them from a garden center. Ensure that the kind you choose will only mature to a height of 4 to 6 inches and a length of 2 to 3 feet. Take a look at the plant labels. The color and elegance of the flowers might easily cause one to become sidetracked.
Choose a spot for your petunias where they will get at least 4 to 6 hours of direct sunlight per day. Best is direct sunshine. Trailing petunias bring color and elegance to a hillside or retaining wall, while being frequently utilized in containers or hanging pots. The majority of trailing petunias produce 2 inch-diameter flowers. Their green leaves are barely perceptible at their height.

Develop the soil. If you are planting petunias in the ground, turn the soil over and add peat moss, well-rotted leaf compost, or manure. Mix potting soil, peat moss, and perlite to create a well-draining substrate for hanging baskets and other containers. Petunias require regular watering. Most hanging baskets and containers need to be watered every day.
The petunias should be planted at the suggested spacing. If the plants are placed too closely together, they may get root-bound, which may decrease their flowering season and harm their health. Eliminate any flowers that are dead or wilted. Petunias should be pruned after planting in order for them to expand and develop their root systems more quickly, according to some growers.

Use a well-balanced 8-8-8, 10-10-10, or 20-20-20 fertilizer once a week. A rate of 2 pounds per 100 square feet is advised by the University of Minnesota Extension. The best fertilizer for hanging plants and containers is liquid fertilizer.
Leave the double blossoms alone. Single flowers don’t need to be deadheaded because they clean themselves. An angle of 45 degrees should be used when planting trailing petunias in hanging baskets or containers to promote cascading.
Spreading trailing petunias:
Stunning petunias are among the most well-liked flowers due to their amazing blossoms and protracted blossoming time. By summertime, they become lanky like most annuals do, so you should cut the shoots back to about half their original length. See how to grow petunias and care for them to keep them in bloom.
About Petunias
In most regions, petunias are cultivated as annuals, however in zones 9 to 11, they can be grown as sensitive perennials. The blooms bloom from spring till frost and come in a variety of hues and patterns.
These vibrant annuals are frequently used in borders, pots, hanging baskets, and even as temporary groundcover because of how well they can brighten up a front yard. Some even have a faint scent. Their spread along the ground can be anywhere between 18 inches and 4 feet, and their height can range from 6 inches to 18 inches.
Types of Petunias
Petunias are categorized into several categories, primarily according to flower size:
- The most resilient and productive petunias are multiflora varieties. They are perfect for summer bedding or in a mixed border because they have smaller but more numerous flowers (because they are more tolerant to wet weather).
- Grandiflora petunias grow well in hanging baskets or pots since they have very enormous flowers (because they are more susceptible to rain damage). Due of their susceptibility to rot during humid, hot summers, these huge petunias frequently do not thrive as well in the south.
- Between the grandiflora and the multiflora groupings, floribundas constitute a middle ground. Similar to multiflora types, they are free-flowering and have medium-sized blooms.
- Compared to other petunias on the market, milliflora petunias are significantly smaller. Despite just being 1 to 1 1/2 inches across, the flowers are abundant and bloom the entire season.
- Low-growing, spreading or trailing petunias can spread as much as three to four feet. The flowers develop throughout the whole length of each stem, forming a stunning, vibrant groundcover. They can be utilized in hanging baskets or window boxes.
Petunias require full sun to avoid becoming spindly. In the shadow, they don’t typically flower well.
Particularly in containers, the soil should be able to drain effectively and not become too damp. In order to encourage the best growth, it should also be relatively fertile. Before planting, amend poor soil with finished compost.
When to Plant Petunias
- It is simplest to get young plants from a nursery that offers flats of petunias. Be on the lookout for short, compact plants. Leggy petunias with an abundance of flowers won’t establish themselves as quickly.
- Petunias should be started indoors 8 to 10 weeks prior to your final spring frost date if you wish to grow them from seed. (View the frost dates in your area.)
- After your last spring frost date, plant young petunias outdoors, but keep a close watch on the weather forecast and shield young plants from late frosts.
How to Plant Petunias
- Petunia seeds need a lot of light to grow because they are so tiny (like dust!).
- Plant the baby seedlings outside as soon as they have three leaves.
- Plants should be placed about a foot apart.
- Use a potting mix for pots that will drain effectively if you’re growing petunias in them.
- You shouldn’t have to worry about watering petunias frequently because they can withstand heat well. Once a week, thorough watering should be enough (unless there are prolonged periods of drought in your area). Avoid shallow irrigation since it promotes shallow roots.
- Petunias that spread and those grown in containers will need more frequent watering than ones that are rooted in the ground.
- To stimulate their quick development and profuse blooming, treat petunias once a month with a balanced fertilizer. Double-flowered cultivars benefit from fertilizer applied every two weeks.
What to Do With Leggy Petunias
- After pruning, give the plants plenty of fertilizer and water to encourage flowering and new development. At first, the plants may appear ragged, but they will recover with more color and blossoms.
- In milder areas, older garden petunia plants can benefit from rigorous pruning (within a few inches of the base) to re-encourage vitality. However, the remaining leaves should be left on the plant.
- Deadheading is the process of removing faded, old, or dead blossoms from plants in order to increase blooming and aesthetic appeal, especially for petunias with larger flowers. Seed pods are kept from competing with blossoms for the plant’s food sources by deadheading. Clippings can be recycled by being placed to a compost pile.
- The “Carpet Series” is particularly well-liked. They are perfect for ground cover since they are compact, early bloomers, with flowers that range in size from 11/2 to 2 inches, and have a variety of colors.
- The flowers of the “Primetime” series are uniformly and compactly spaced every 21/4 inches.
- Early, compact, double, deep lavender blue ‘Heavenly Lavender’ has 3-inch blooms on 12- to 14-inch bushes.
Petunias that trail are they perennial?
One of the most popular summer bedding plants in our region is the petunia, which blooms from mid-summer until the first hard frosts of autumn. Their profusion of flowers fills gardens with wonderful color.
The trailing kinds liven up hanging baskets and flow down the edges of containers, while the compact, bushy varieties are ideal for planting in beds and borders.
Petunia flowers come in a vast array of colors, single and double blooms, smooth or ruffled petals, solid single, striped, veined, or picotee-edged colors, and even fragrance. The issue of ancient petunia types turning to mush in a wet summer has also been eradicated by recent breeding.
Petunias are perennial, despite the fact that the majority of bedding kinds are produced from seed annually as annuals. The perennial trailing varieties, like Surfinias, are cultivated from cuttings or young plants.
Cultivation
Although they will tolerate a little moderate shade during the hot, sunny summers, petunias like to be cultivated in full sun. They thrive on soil that is rich in nutrients, moist but well-drained. To keep moisture in sandy soils that drain very well, add lots of organic matter to the soil, such as garden compost, well-rotted manure, or other soil-improving materials.
Petunia varieties
Grandifloras, which have larger flowers, or multifloras, which have smaller flowers and are more resilient to rain, are the two varieties used as bedding.
The Surfinia, Wave, Tumbelina, Supertunia, and Cascadia series of petunias spread or trail.
Sowing petunias
Petunias can be grown from seeds inside with warmth in cell trays, seed trays, or tiny pots at a temperature of 18 to 24C as an annual or bedding plant (65-75F).
When plants are big enough to handle, prick them out into cell trays or tiny pots and let them continue to grow at a temperature of 50 to 65 degrees Fahrenheit (10 to 15 degrees Celsius) in good light.
Before planting the seedlings outdoors once all danger of frost has passed, gradually acclimate them to outdoor circumstances for 7 to 10 days.
Young petunia seedlings are available from garden centers and mail-order suppliers in the late winter/early spring if you don’t have the resources to grow them from seed.
Planting petunias
Make a good-sized planting hole that can readily fit the rootball. Fork in a layer of organic material, such as compost or planting compost, at the bottom of the hole.
Place the rootball in the planting hole, adjusting the planting depth (except for hardy fuchsias) until the top of the roots is level with the soil surface and the rootball is planted at the same depth as it was growing. Fill the planting hole with the excavated soil after adding more organic matter to it. Put some granular general feed on the soil and thoroughly wet it in. The soil can be kept moist and weeds can be controlled by adding a 5-7.5cm (2-3in) deep mulch of well-rotted garden compost or something similar over the soil. If you have a warm greenhouse, you can plant baskets and containers in the spring, let the plants mature, and then move them outside in late May or early June. You’ll have flowers earlier in the summer if you do this.
How to care for petunias
When there are protracted dry spells in the summer, water the soil frequently to keep it moist. Plants in containers will require routine, possibly daily watering with the intention of maintaining evenly moist compost. But be careful not to overwater, as this may make the plants leggy and produce few blossoms.
To ensure a steady supply of blossoms throughout the summer, feed your plants with a liquid plant food on a regular basis. Up to the first autumnal frosts, a high potash liquid plant feeding will promote more, better blooms.
The show will last longer if faded blooms and any sprouting seed pods are removed. Cut back straggly plants severely before feeding them with a liquid plant food to encourage fresh new growth and an abundance of blossoms.
Fall is the greatest time to dig up and compost bedding petunias that have been harmed by frost.
Overwintering petunias
Trailing perennial kinds can be pruned back severely in the fall, cleaned up by removing any dead or broken growth, and then gently lifted. They should be overwintered in a bright, frost-free location, preferably a greenhouse or cool conservatory, in pots just large enough to hold the rootball and with some fresh potting compost around the sides.
Propagating perennial petunias
Cuttings taken in March or April from plants that overwintered or in August or early September from perennial, trailing kinds can be used to create new plants.
Select young, robust, vigorous stems that aren’t in bloom. Cut back one or two stems at the back of the plants severely to promote vigorous regeneration if you are unable to locate adequate growth. collect clippings 7.5–10 cm (3–4 in) long and positioned immediately below the node or junction of a leaf. In pots of gritted cuttings compost, place five or six cuttings at the base of the lowest leaves after removing the leaves from the lower two-thirds of the stem. Put the pots in a propagator or a plastic bag and set them somewhere with good light—but not in the sun—to root.
In two to three weeks, the cuttings should have taken, at which point they can be potted up separately and continued to grow.
