Trailing Petunia surfinia

The Best Cascading Supertunias for Hanging Baskets

Petunia surfinia is a cross between the wild petunia, Ruellia humilis and Petunia x hybrida. It was bred to flower more heavily than other petunias and its cascading flowers stand up to rain, wind and heat better than most.

Pinching Petunias:

The Supertunias offered on this page are self-cleaning and don’t need pinching back to keep them blooming.

Surfinia petunias are widely used in window boxes across Europe where their trailing growth habit can be exploited. Plants grow quickly to 6 inches tall by 4-5 feet wide. They are one of the best cascading petunias for hanging baskets as they drape beautifully and can trail to 4 feet in a single growing season.

This petunia is unique also in that it flowers all over and not just on top. This is an asset when growing hanging baskets. This plant blooms non-stop throughout the growing season in a wide variety of hues from baby pink to deep purple to fire engine red.

There are more than 15 different named cultivars. Some bear the traditional funnel-shaped petunia flowers while others sport ruffled double blooms.

Planting Petunias in Hanging Baskets

  1. Use a fast draining mix with watering crystals. This will keep the plant from wilting so quickly.
  2. Add a large scoop of organic compost to the potting mix prior to placing the plant into it.
  3. Petunias are heavy feeders so mix in a little slow release fertilizer.
  4. Place a single plant into the center of a 12 inch basket. It will quickly fill the container and begin to trail down the sides.
  5. Suspend the pot from a sturdy support.
  6. Water often enough to keep the soil from ever completely drying out.
  7. Add a water soluble fertilizer to the water every week or two.

This is a tender perennial petunia in zones 9-11 (because of its Ruellia humilis parentage) that is usually grown as an annual in zones 3-8.

Once you try this tough cascading petunia you will certainly want to grow more of them. Propagate plants by cuttings instead of seeds as petunia hybrids will not come true from seed.

Growing petunias can be very rewarding as long as you chose the right variety for your location. For instance, the grandifloras perform poorly in the rain and are best grown indoors.

The multifloras and floribundas are better used outdoors.
