Petunias tend to be low growing and bushy tender perennials that are usually grown as annuals. Their petals come in a few different styles: trumpet-shaped, doubled, ruffled and fringed. Their colors range from light pink through dark red, and pale blue through deep purple. They can also be found in white, cream, and even a new bright yellow. Many petunias have veins of alternating stripes or accent colors.
In this post we'll focus on yellow petunias, focusing on the different types and care tips, ending with a lovely photo gallery of yellow petunias.
What Are Yellow Petunias?
Most modern petunias descend from the Petunia axillaris, also known as the large white petunia, and the Petunia integrifolia, the violet petunia. These initial hybrids were produced in Germany and England in the early 1800s, and their hybridization proved so stable and popular that botanists refer to them as P. hybrida.
Petunia is the genus of 20 species of flowering plants of South American origin in the family Solanaceae and the subfamily Petunioideae. Petchoa is a hybrid genus that is derived from crossing Calibrachoa and Petunia.
There are a few basic petunia hybrids, like the Grandiflora, multiflora, milliflora, doubles, waves, surfinias, supertunias, cascadias, and petitunias. Each hybrid has its own characteristics that are unique to them, and some have been introduced somewhat recently.

Yellow Petunia Care Tips
Petunias offer long term color in the summer and have the ability to brighten any garden. They aren't difficult to grow; on the contrary, proper petunia care is simple and easy. The needs of yellow petunias aren't much different from those of other petunias.
Here are a few care tips –
1. Petunias require regular watering, at least weekly, and as much sunlight as possible to be at peak performance.
2. Petunias can tolerate cooler weather but are not frost tolerant. Wait until the earth stops frosting over to plant them.
3. Some varieties of petunias require frequent deadheading, such as floribundas and older Grandiflora varieties like the Aladdin series.
4. Monthly feeding will give petunias the energy they need to stay in bloom.
5. Petunias enjoy a slightly acidic soil pH.
6. Some varieties of petunias can be pummeled and destroyed by rain. Choose weather-resistant varieties.
7. Pests often flock to weeds and decaying plant material, so keep the planting area weeded and rake up fallen plant debris to keep harmful insects away from your petunias.

The name "petunia" originates from the word "petun" which stands for "tobacco" in Brazil. These two types of plants are genetically related and can be crossbred.
Petunias that are commonly found are edible. Their flowers have a sweet and spicy taste.
Petunias have green leaves that are covered with hairs and can be heart-shaped or ovate. They are usually alternately arranged on the stem.
Petunias come in red, yellow, pink, purple and white, and are also available in a mixture of colors.
Though petunias attract helpful bugs like bees, they also attract caterpillars, leaf miners, and mites that can be harmful to their health.
Petunias can often be identified by their trumpet shape. The center of each flower contains the stamen and a darker spot, with the color becoming lighter toward the edges.
Petunia flowers can have flowers as large as 4 inches in diameter, and they have five-lobed petals, with varieties including double flowers and ruffled petals.
