The Gorgeous Flower You'll Want To Grow With Petunias In The Garden

Petunias are a popular choice for many gardens due to their size, numerous blooms, and multi-colored petals that bloom throughout the seasons. These colorful petals stand out in any garden. Planting petunias alongside flower varieties that complement their hues and size can elevate your garden’s appearance even further.

Snapdragons, for instance, with their tall stems and various-colored petals, can produce a flush of color when planted alongside vibrant petunias. Snapdragons grow thin and tall, with their petals blooming on the upper half of the stem, exposing their green bottoms. This creates the perfect place for petunias to blossom. The varying heights of the two plants allow them to bloom perfectly side by side without overlapping each other.

Petunias thrive in warmer climates and bloom in the spring, summer, and fall. This makes snapdragons the ideal companion since they require similar weather conditions that allow them to bloom for multiple seasons. Pairing these two plants in your garden can significantly enhance its beauty.

Although they don’t grow to the same height, both petunias and snapdragons enjoy full sun and the same soil. This allows them to thrive when planted together. Even if you don’t have the greenest thumb, both of these varieties are easy to grow, and even the worst gardeners can handle them. While they bloom differently, they have similar nutrient preferences, making it seem like you’re growing only one type of plant.

The contrasting sizes create a fuller-looking garden

The key difference between the petunias and the snapdragons centers around their height. Snapdragons grow immensely tall, up to 36 inches, while the petunias stay closer to the ground when they bloom, growing up to 18 inches tall. Because the petunias grow shorter, they have more of an advantage in covering the snapdragon’s stems, making them look fuller. Instead of leaving pockets of space between the snapdragon’s stems, the petunias will grow between them to fill the space. As they grow, the snapdragon’s stems will hide behind the petunias. Once the petunias grow to full height, they’ll stop right before the snapdragon’s petals, adding a lush layer of flowers and beauty.

Further, the multiple colors of the petunias’ bloom will add more color to your garden and surrounding snapdragons. You can plant various hues from both flowers to have a rainbow of colors or pick two complementing tones for a contrasting look. You can plant multiple bundles of petunias and snapdragons around your home for a pop of color. For instance, grow vibrant flowers along your walkway or front side of the house for an eye-catching appeal. However, if you’re worried about too much color overwhelming your space, the petunias grow additional green stems with leaves that will help balance the many vivacious hues.

Planting companion flowers together makes the process extremely easy when they require the same nutrients. Petunias and snapdragons thrive in the same soil and climate. They both need moist, well-draining soil that’s acidic to neutral-based. It’ll allow them to grow and bloom adequately, making them the perfect pair of flowers to plant together.

While both plants can thrive in acidic soil, they prefer a more neutral soil with a pH level of 6 to 7 filled with rich nutrients. They’re not heavy feeders, so they don’t need too many nutrients or water. They’ll grow stunningly as long as their soil stays moist and covered with slight organic matter. When choosing where to plant petunias and snapdragons, always pick a sunny location. They don’t do well in shady areas, causing few petals to bloom, so opt for a full-sun area. Since they’re in bright spaces, keep an eye on their soil to ensure it stays moist. You don’t have to water them frequently when they’re established; once every other week should be enough unless you notice their soil drying out or an extreme summer heat is occurring.

On the other hand, when both of your plants are starting to grow, you can pinch off the tip of their stems to encourage good branching that will help them appear thicker and bushier. Deadheading them will improve their appearance and extend their blooming season so you can enjoy your lively flowers for many seasons.
