What are Wave Petunias?

Wave petunias are a type of petunia that was first introduced in the 1990s. They were developed by PanAmerican Seed Company in collaboration with a Japanese company named Kirin Brewery.

Wave petunias are known for their cascading growth habit, which makes them perfect for hanging baskets, window boxes, and other containers.

One of the most notable features of wave petunias is their ability to spread out and cover a large area. They can grow up to 4 feet wide and 2 feet tall, making them an excellent choice for ground cover in a garden bed.

They are also known for their durability and ability to thrive in a variety of growing conditions.

Different Types of Wave Petunias

There are several types of wave petunias available, each with its unique characteristics. Here are some of the most popular varieties:

Easy Wave

Easy wave petunias are a low-maintenance variety that is perfect for beginners. They are the most versatile, and their growth habit makes them perfect for in the ground, containers, and hanging baskets.

They tolerate heat and cooler night conditions and grow a bit more mounded than the original.

Easy wave petunias come in a variety of colors, including pink, purple, white, and red. There are also some bi-colors.

Tidal Wave

Tidal wave petunias are known for their large blooms and fast growth rate. They can grow up to 3 feet tall and 4 feet wide, making them perfect for filling in large spaces.

They’re the biggest and most vigorous in the Wave Petunia family with fantastic recovery from rain. 

How far they spread and how high they get is determined by how closely plants are spaced – the closer the spacing, the taller the plants.

I grew Tidal Wave Silver and it grew up and over other plants like some tall daisies, a rose, and more. These things are great for growing over a wall you wish to disguise!

Shock Wave

Shock wave petunias are a variety that features petite flowers and a more subdued nature.

They spill over the sides of container groupings without overpowering the other plants.

They are smaller than other wave petunias, making them an excellent choice for borders or edging.

Shock wave petunias are perfect for gardeners with a smaller space and come in several decorator color combinations.

How to Grow Wave Petunias

Growing these petunias is easy, even for beginners. Here are some tips to help you get started:

  1. Choose the right location: Wave petunias do best in full sun, but they can also tolerate partial shade. Make sure the location you choose receives at least six hours of sunlight per day.
  2. Prepare the soil: Wave petunias prefer well-draining soil that is rich in organic matter. If your soil is heavy or clay-like, you may want to add compost or other organic material to improve drainage and fertility.
  3. Plant your petunias: If you’re growing wave petunias in containers or hanging baskets, choose a high-quality potting mix that is designed for container gardening.

    Use only two or three plants per 12 inch pot. Don’t overcrowd them!

    If you’re planting them directly in the ground, space them about 12 inches apart and plant them at the same depth as their nursery pots.
  4. Water regularly: Petunias need regular watering, especially during hot, dry weather. Water them deeply at least once a week.

    If they are in containers it will need to be done more often. Actually, timing will depend on the weather and how fast they dry out.

    I like to use a moisture meter, they are inexpensive and can give you an idea of how wet the soil is deeper into the pot.
  5. Fertilize weekly: Wave petunias do require a lot of feeding, they need it as they are pushing out blooms like crazy.

    When you plant them in containers using a high-quality potting soil it usually has enough good stuff in it to act as a slow-release feed but you will need to add a liquid feed weekly during the height of the growing season.

    This is my favorite organic liquid plant food. It feeds not only the plant but also the soil!

    If you are using a more economical type potting soil and are not sure of its nutrient value then adding a cup of worm castings per gallon of soil is recommended.

    There are other granular organic feeds you could use also, Espoma Plant Tone, EB Stone Organics, or any good quality you can find at your local nursery.

Some ask if Wave Petunias are better than Proven Winners Supertunias. That is a valid question and opinions vary.

In my experience the Wave Petunias do better in my conditions, the Supertunias I have grown don’t do well until late August and I want petunias blooming all summer long.

I believe it may be because of our cool summer nights. My friend, who lives in an area that has warmer nighttime temperatures do great with Supertunias.

Another thing I love about Wave Petunias is I can grow them from seed and thus save money in the long run.
