Surfinia is actually a kind of hanging petunia that bears hundreds of small bell-shaped flowers. It is often used as a cascading flower to cover balconies and deck overhangs.

Planting, sowing surfinia
How to plant surfinia
It is recommended to plant this petunia in spring, after any risk of freezing is over, because it doesn’t survive freezing well.
- Surfinia in flower beds
Blend garden soil to soil mix.
- Surfinia for pots, garden boxes, containers
If you’ve purchased your plants in nursery pots, mix together garden earth and soil mix.
It’s also possible to use only soil mix, since this would further boost plant growth and blooming.
- Surfinia as a hanging plant
Choose hanging plant soil mix which tends to be lighter, otherwise you’ll have problems with this type of planting.
Sowing seeds from a surfinia
Surfinia plants may produce seeds, though less than regular petunia. These seeds might also be sterile, since the plant is a hybrid (see the surfinia origin story below). However, experience shows that surviving seeds will also be very beautiful! Simply, they’re a new kind of petunia and not the actual “Surfinia Petunia ®” anymore.
- For these seeds, practice sowing in a tray indoors, in your home, starting in February/March.
- Simply press the seeds down to ensure they stick to the special “seedling soil mix”, without covering them over.
- Water regularly to retain moisture, but not too much.
- When the first leaves pop out, transplant to nursery pots and wait for the last frost to have passed before planting them outdoors.
Whether the plant is in a container or in the ground, select a sun-filled spot for maximum blooming.
Pruning and caring for surfinia
To enhance flower-bearing, you can remove wilted flowers regularly.
During spells of high temperatures, feel free to water in the evening to avoid having your petunia dry out.
- It is preferable to let the ground dry up somewhat before watering again to avoid excess moisture.
Learn more about surfinia
It shares with us the gift of bearing beautiful flowers for a long time.
It is a kind of weeping, cascading petunia that produces rolling swaths of flowers.
Since it is easy to grow, it will develop well in garden boxes, suspensions and also directly in the ground.
The blooming spreads from the beginning of spring until fall. It loves sun and well-drained fertile ground.
Where does surfinia come from?
The origin of the surfinia plant dates back to 1987. Surfinia was bred in Japan by Suntory Flowers. Initially, it started as a vigorous wild petunia discovered in Brazil. Dr. Sagazaki hybridized it with other petunias so that the many colors we see today could arise.
In short, the surfina is a petunia that gained a trailing habit and an excellent resistance to disease and other hardships. Even today, new patented varieties are developed and propagated through cuttings by growers across the world.
The word “Surfinia” is a trade name, and it refers specifically to plants multiplied through cuttings. Any seeds from these flowers that grow into flowers won’t be exactly the same because of cross-pollination, so they can’t be called “surfinia” anymore. They are, however, petunia!
