Different Types of Petunias
Petunias are easy to grow, can adjust to most types of soils and offer an unparalleled range of colors and blooming patterns. When choosing petunias for your garden, know the basic petunia types and their defining features.
1. Grandiflora Petunias
Grandifloras are counted among the oldest of petunia varieties. They grow nearly 12 inches high in shades of purple and fucshia. They have the biggest flowers among all petunias, and are particularly famous for their large, seasonal blooms. The most popular varieties include:
- Prism Sunshine
- Supertunia Silver
2. Multiflora Petunias
Flowers are a bit smaller than the Grandiflora variety due to their compact formation. The vary from light pink to dark red, with centers of yellow or white or even white stripes on the petals. Stems are stronger, making them better suited for windy areas. Multiflora petunias are common in household gardens, as they are resistant to slight temperature and moistures changes.
Hybrid Multiflora petunias have been introduced that are particularly suited for gardens exposed to extreme winter conditions. They are often called double petunias, as the double-flowering Multiflora varieties are more common than the single-flowering Multifloras. The Floribundas is a member of the Petunia Primetime Series.
3. Wave Petunias
The name comes from the wavy shape of the flower petals, and the entire flowering cluster that has a ribbon-like outer form. They grow about 6 inches tall and 4 inches wide in white, pink and lavender. Their smaller size makes them ideal for indoor potting. They react well to shaded areas and don't need deadheading. Varieties include:
- Double wave petunias
- Easy wave petunias
- Tidal wave petunias
4. Cascadia/Surfinia Petunias
Surfinia and Cascadia are 2 different types of petunias, but are usually clubbed as one single type. They are famous for their abundant flowering. Most Cascadias can easily grow to about 18-inches tall with flowers that range from pale yellow to bold purple.
- Blue Spark
- Pink Vein Petunias
5. Superbell Petunias (Calibrachoa)
With bell-shaped blooms, they are also called Million Bells and Superbells. They are among the smallest of petunias but may look bigger due to the clustered appearance of the seasonal blooms in shades of gold, peach, coral and magenta. Calibrachoa hybrids are the most sturdy and affordable modern-day petunia hybrids. They need little or no deadheading. The most popular type is the Dreamsickle petunia.
6. Supertunia Petunias
Supertunia is not a very common petunia, found most in professionally-maintained gardens. These hybrids are grown from cuttings of branch and root tips and not the seed. They need frequent doses of plant food. A regular supply of nitrogen-rich fertilizers is recommended. Supertunia is known for being highly weather tolerant and can survive the most demanding of winters. Common hybrids include the Red Supertunia and Blue Veined Supertunia.
