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 these petunia flowers stand up to rain, wind and heat better than most.
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.
This is a perennial petunia (because of its Ruellia humilis parentage) that is usually grown as an annual.
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.
