What Are Grandiflora Petunias?
Grandiflora Petunias are known for producing some of the largest flowers found on any petunia. The word "Grandiflora" literally means "large flower."
These petunias typically feature:
- Large blooms often 4 to 5 inches across
- Show-stopping flower displays
- Excellent container performance
- Dramatic flower colors
- Classic petunia appearance
Because of their huge flowers, Grandiflora Petunias are often chosen when gardeners want maximum visual impact.
One beautiful example is:

Its striking veined blooms create eye-catching displays in containers, flower beds, and patio planters.
What Are Multiflora Petunias?
Multiflora Petunias produce smaller flowers than Grandiflora types, but they make up for it by producing a much larger number of blooms.
Characteristics include:
- Smaller flowers
- Heavy flowering
- Better weather resistance
- Excellent garden performance
- Continuous bloom production
Many modern spreading petunias and Wave Petunias share characteristics that make them excellent performers in landscapes and larger plantings.

Flower Size Comparison
The most obvious difference between these petunia types is flower size.
Grandiflora Petunias
Grandiflora varieties produce:
- Larger flowers
- More dramatic blooms
- Greater individual flower impact
- Show-quality appearance
Many gardeners grow Grandiflora varieties specifically because they love the oversized flowers.
Multiflora Petunias
Multiflora varieties produce:
- Smaller blooms
- More flowers per plant
- Better flower coverage
- Consistent color displays
While each bloom is smaller, the overall plant can appear completely covered in flowers.
Weather Resistance
Weather tolerance is one area where Multiflora Petunias often excel.
Grandiflora Petunias
Because of their large flowers:
- Rain can damage blooms
- Wind may affect appearance
- Flowers may require more maintenance
Multiflora Petunias
Smaller blooms generally:
- Recover faster after rain
- Handle wind better
- Maintain appearance longer
- Require less maintenance
For gardeners in rainy climates, this can be a significant advantage.
Choose a Petunia Seed Pack for Your Space
Which one should I choose? For big flowers on compact plants, start with Limbo Mix Picotee or Mambo Blue Picotee. For a veined mounding display, try Hurrah Blue Vein. For upright bedding and patio color, compare Madness Blue Star and Tritunia Mix. For a spreading basket or window box, choose Shock Wave Violet.
Modern petunia series do not all fit neatly into just two categories: Madness is a floribunda series and Shock Wave is a spreading series. Use each listing's flower size and growth habit to choose the right plant, rather than assuming every variety below is strictly grandiflora or multiflora. These are 25- or 50-seed packs, not live plants.

Many gardeners actually combine both types in different containers throughout their landscape.
