Which Petunias Don’t Need Deadheading

For example, the Supertunia and Wave series of petunias have grown to be so well-liked that they have their own class of their own.


The Proven Winners plant line’s Supertunia series of petunias are incredibly active bloomers with the benefit of not needing deadheading because they are self-cleaning. Flowers come in a wide variety of hues, such as pastels, vivid neons, and mixes. Depending on the cultivar, growth patterns might range from somewhat mounded to trailing.

  • The fantastic landscape plant known as Supertunia Vista petunias has medium-sized flowers that mound up to 24 inches and spread three to five feet. They can dangle down up to four feet in huge containers.
  • Petunias known as Supertunia Charm make excellent thickly branching container plants with tiny flowers. They also make excellent landscape plants in areas with poor drainage.
  • Supertunia Strongly trailing petunias with medium-sized flowers are available. They can be cultivated at the front of flower gardens and make good spillers in pots, hanging baskets, or window boxes.
  • Supertunia Large, totally doubled flowers on double petunias make them ideal for pots or the front of garden beds.

What varieties of petunias don’t require deadheading?

When it was initially released, the wave series caused quite a sensation, and the flowers kept getting better. Wave petunias only reach a height of six inches but can stretch out to four feet. Wave petunias do not require deadheading, which is another quality that makes them worthwhile to grow. The negative is that they do break down during the hottest summer months. Long-term heat reduces wave petunias’ blossoming, but a little pruning typically makes them bloom again. Wave petunias are excellent groundcovers and container trailers. Additionally, there is a “Tidal Wave” series that tends to stand more upright.

Does deadheading apply to all petunia varieties?

Not all petunia varieties require deadheading. These days, there are novel hybrids that clean themselves and require little to no upkeep.

Check the information on the plant tag or inquire at your neighborhood garden center if any types of self-cleaning petunias are available.

A great approach to keep petunias flowering and healthy throughout the entire gardening season is to deadhead them. By the middle of the summer, if you’re sick of your petunias appearing overgrown and scraggly, pinch away!

What occurs if petunias aren’t deadheaded?

Comparatively speaking, petunias planted in containers typically need more frequent deadheading. A single bloom may be produced by the plant if deadheading is not done. The petunia has slender stems and no flowers for the remainder of the growing season.

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.


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.
