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.
All petunias considered Wave petunias?
Petunia plants come in four primary varieties: Grandiflora, Multiflora, Milliflora, and Spreading (Wave). All four can be found in series, which are collections of plants with similar sizes and flowering schedules. The spectrum of hues of various petunia blooms within each series is the sole characteristic that varies.
Varieties of Petunias
Grandiflora petunias, which were created in the 1950s, are the earliest varieties. Grandiflora petunia variants have bouquet-shaped plants with blooms up to 5 inches (12.5 cm) across. Even while the flowers are magnificent, by midsummer they start to look worn out and spindly. Grandiflora petunias thrive in mild summers with little to no excess moisture or humidity.

- Ultra
- Dream
- Storm
- Daddy
- Supermagic
- Supercascade
Petunias with many florets have smaller, more abundant blooms. Multiflora petunia cultivars are good for windy climates because of their sturdy stems. Particularly in wet weather, the blooms last a little while longer than Grandiflora petunia kinds. There are single and double kinds of multiflora petunias.
Among the preferred Multiflora petunias are:
- Primetime
- Celebrity
- Carpet
- Horizon
- Mirage
Petunia variants known as milliflora produce masses of 1- to 1-1/2-inch (2.5-4 cm) flowers on tiny plants. The plants are typically around 8 inches (20.5 cm) tall and wide when they are fully grown. Early blooming milliflora petunias are frequently grown in hanging baskets or containers. They are easy-to-care-for plants that don’t require deadheading.
A more modern kind, spreading, or wave petunias, have flowers that are normally around 2 inches (5 cm) across. The plants look fantastic in pots and make excellent ground covers, generally spreading 2 to 4 feet (0.5 to 1 m) by the end of the season. They normally don’t need deadheading and can handle heat and drought fairly well.
Can you grow Wave petunias alongside common petunias?
In hanging baskets, spreading petunias thrive! Their sprawling vines will drapingly hang over the side of your basket, giving it a lovely appearance.
You should plant anywhere between 1 and 3 plants for your hanging basket, depending on the spreading petunia species and hanging basket size.
Make sure not to overfill the hanging basket while planting your spreading petunias with other plants. Spreading can engulf other plants if they are overcrowded, so be sure to give each plant plenty of room to grow!
Are Supertunias and Wave Petunias the same thing?
Supertunias can be planted with other flowers more easily than Wave petunias since they have a smaller root system. They don’t grow as quickly or aggressively as others. They are available in several sizes and varieties, just like Wave petunias. Variables include bloom size and growth trends.
The best 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.
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.
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.
Wave petunias: Should I deadhead them?
Wave Deadheading Wave plants naturally do not need deadheading because of their abundant flowering, but doing it sometimes will increase flower production even more. Remove the blossom and the tiny stem holding it to the plant when it starts to fade.
How are Wave petunias kept in bloom all summer long?
It all boils down to how healthy your plant is. A Wave petunia can reach its full potential if it is given the right care. This denotes abundant and robust blooming.
The opposite is also accurate. Your Wave petunia plant might require a little more care if you discover that it didn’t get off to the ideal start or didn’t get the early attention it required.
Your Wave petunias might be able to recover, though, if you concentrate on some of the locations listed below.
Make sure they are getting plenty of sunlight
Petunias in general, including wave petunias, adore the sun. They will require at least six hours of sunlight, with a full day of sunlight being ideal.
Lack of exposure to sunshine may be the cause if you planted your Wave petunias in a shaded area and the plants aren’t flowering as you’d like them to.
Begonias are a common choice if you’re seeking for a plant that will still bloom even with less sunshine.
Wave petunias are frequently planted in hanging baskets by growers. One of the most often used plant species by gardeners for hanging plant arrangements. Simply relocate the container to a location where it will receive more sunlight if you are growing them in a hanging basket or pot.
Keep them wateredbut don’t overwater them
On the other hand, you might notice that your Wave petunias don’t bloom as much if they receive too much sunlight and insufficient water.
Make sure the plant is adequately watered because it needs sunlight and water to survive.
Checking the soil’s moisture in the top inch or so is a smart technique to make sure. It’s probably fine if the soil near the surface is at least slightly damp.
If you’re growing Wave petunias in a hanging basket, you can lift the basket to feel how much water it needs by doing so. If it is adequately watered, it should feel noticeably heavy, and if it is dehydrated, visibly light.
If overwatered, wave petunias are susceptible to root rot and other illnesses, so take careful to water them just enough to keep them healthy. Your Wave petunias will recover in this way and produce an abundance of blooms.
Fertilize the plants when needed
A water-soluble fertilizer should be added when necessary while watering. Wave petunias require nutrients, just like other plants, thus it’s critical to maintain a healthy fertilization level.
Follow the directions on any fertilizers you use, and consider the season. During the summer, when you might be watering every day, you might only need to water once or twice a week, but this frequency will probably change in the spring and fall.
If you neglect to fertilize the plants, Wave petunias are less understanding than Supertunias. You may tell they need more nutrients if you notice the vines starting to turn yellow.
Give them space
Make sure you give the space that spreaders like wave petunias need! It is advised that you plant them at least a foot apart because their vines may get up to 4 feet long.
When wave petunias are grown in containers or hanging baskets with restricted root space, they might not be able to reach their full potential and produce as many blooms.
Trim the plant to promote growth
Last but not least, pruning back your Wave petunias is a fantastic strategy to encourage the development of new flowers. Cutting back a plant when you want it to grow more may seem counterintuitive, yet it is frequently necessary when dealing with a straggly plant.
Treat it for budworms
It’s likely that despite your best efforts, the Wave petunias are still in bloom. The budworm might be to blame.
Budworms are an insect pest that wreak havoc on a variety of garden plants, particularly petunias.
If your Wave petunia plant is being affected by budworms, you’ll probably notice holes in the blossoms. These seem to be a problem in Pennsylvania in the late summer.
Budworm can be handled in a variety of ways. Thurocide has proven to be efficient in eliminating budworms and reviving Wave petunia blooms.
Don’t overpack your basket
As previously indicated, Wave petunias grow quickly. When the plants are young, you don’t want to make the error of overstuffing your Wave petunia basket. Wave petunias can still outcompete other plants in a hanging basket even though they aren’t quite as vigorous as Supertunias.
You could get away with planting only one Wave petunia plant per hanging basket, but many people will plant three to really achieve a good show (stick with odd numbers). This will primarily depend on the size of your basket, but for a typical 12-basket arrangement, 3 plants should be more than plenty.
Be careful not to crowd any of the plants when planting Wave petunias in a hanging basket with another plant.
Plant the hanging basket early
Wave petunias are excellent growers, so even plantings made later will succeed. However, the earlier you can safely put them outside, the better—as with any annuals! You can do this to get out of the house and see some blossoms before everyone else.
Fertilize throughout the summer
Even though your hanging basket’s potting soil already contains slow-release fertilizer, we nevertheless advise fertilizing it all summer long.
Depending on how much fertilizer the potting soil contained, how the plants are doing, and how much sun the hanging basket is getting, some growers advise fertilizing hanging baskets every third watering.
Keep in the sun
Make sure your Wave petunia gets at least six hours of sunlight, while we’re on the subject. With the right care, wave petunias can withstand the sweltering afternoon sun. As a general, petunias enjoy the sun, so make sure they are receiving it.
The Wave petunia may not bloom as abundantly or develop stunted growth if not given adequate sun.
Cut back the Wave petunia for fresh growth
The fact that Wave petunias don’t require deadheading is a big advantage. However, we discover that pruning Wave petunias will increase growth and subsequent blooms.
If you see that the Wave petunia in your hanging basket is straggly or is displacing other plants in the basket, feel free to trim it back.
Keep the hanging basket watered but don’t overwater
While Wave petunias enjoy the sun, when grown in a hanging basket, they will be more dependent on you for water. Throughout the summer, be careful to keep the basket well-watered, especially on particularly hot days.
You might need to water the hanging basket once or more per day during the summer heat.
Check to see if the soil’s top inch or so is damp to determine whether it needs some water. Alternately, you can raise the basket from below to gauge its weight. If watering is required, a Wave petunia hanging basket will be substantially lighter.
