Petunias and surfinias or hanging petunias can be confused due to their great similarity, but we are talking about two different plants. What happens is that surfinia is a hybrid of petunia, and hence their similarities.

In both cases we are dealing with varieties that stand out for their abundant flowering between spring and summer, especially in warm areas. They have small green leaves, with small hairs and a somewhat sticky feel.

As for the flowers, they show a shape similar to a trumpet and we can see them in a great variety of colors. There are even varieties that combine two colors. The flowers are, without a doubt, the most attractive part of this plant, and they are of a size that makes the small leaves go completely unnoticed.

If they are so similar, then how can we tell hanging petunias from regular petunias? Paying attention to the following points:

  • Flowers. The flowering of surfinia is more abundant, but in exchange, its flowers are a little smaller.
  • Growth. Petunias are creeping plants, that is, they grow at ground level, although some can acquire certain hanging characteristics depending on how they are planted. On the contrary, surfinias meet all the traits to be hanging plants.
  • Reproduction. Surfinias are hybrids of petunias and their stamens are sterile. Since they do not produce seeds, they can only be reproduced through cuttings. On the contrary, we can reproduce classic petunias both through cuttings and through their seeds.
