Interesting Notes:

Petunia is a semi-trailing to trailing annual and tender perennial. Classic petunias are a garden standby. These sunny, heat-loving flowers, originating in North, Central, and South America, were one of the first ornamentals to be hybridized. Petunia flowers all have a similar form and come in a wide array of colors. Their blooms are normally funnel-shaped with either radial or bi-lateral symmetry. Bi-colored flowers, either striped or edged in contrasting colors, are also common in Petunias. All Petunias have medium to fine, green leaves and stems that are sticky to the touch and strongly scented. Some plants have broad, spreading habits while others have a more mounding nature. Petunias are beautiful and easy to grow.

Varieties with a trailing habit are especially beautiful spilling over in hanging baskets and window boxes. Mounding varieties work well as the centerpiece of large potted combinations on the patio. Feature them with a trailing vine or ornamental grass for a more dynamic combo. Taller and fuller varieties go nicely as mixed fillers in the garden. Petunias grow best in moist, fertile, well-drained soil, and are a full to partial sun exposure flower. A unique feature of petunias is that they have sticky stems and have are strongly scented. Petunias will continuously bloom all season long. Key features of this variety are heat, frost, and drought tolerance, no deadheading required, and pleasant fragrance.

Growing Tips for Homeowners:

As with every plant purchase, it is important to look for quality at the start! During the purchasing process, be sure to avoid plants that look exhausted. Finding a fresh young plant, without dying foliage or wilting flowers is very important. Look for rich green foliage as indication of the plant's care thus far. This will ensure an easy start for you, and a long life for your plant.

After locating and purchasing a quality plant at the store, it is important to find the perfect place for it at your home. Petunia is a full to partial sun annual that thrives in the heat. The best time for planting your plant is mid-spring or early summer. Petunias are frost tolerant, in that they will endure an occasional frost during the spring, but be careful not to take your plant outside too early in the spring. If there is consistent nightly frost in your area, it may be best to keep your plant safe indoors, maintaining care in the container and ensuring optimal sun exposure, until it warms up just a bit. Petunias will last from late spring, through the summer, until the finish of fall. They are good pioneer plants in the garden, until other plants become more established.

While the petunia has a high tolerance level and is low maintenance, water application a few times a week is still necessary, and fertilizer or compost application is recommended to ensure optimal plant performance. Petunia blossoms can be damaged by violent rains and improper watering methods. Be sure to apply low to the ground, near the plant’s main stem, avoiding wetting the plant’s foliage, for quick absorption and utilization. While the blossoms can recover after water damage, if you need them to bounce back faster, feel free to remove old flowers to encourage new bloom production. Petunias require a good moisture level but must be well drained. It is important to ensure good drainage in both containers and landscaping, to prevent diseases like root rot. Drainage holes, elevated flower gardens, and proper soil composition are three great ways to prevent root rot and help your plants maintain a healthy moisture level.

Preparing the ground for your plants is always an important key to maintaining healthy plants. Pests like slugs and snails are attracted to the environment created in flower gardens and landscaping. Prevention of these types of pests includes clearing the area of holes where such pests can live. Aphids and thrips may also pose a threat to your Petunia, but are usually taken care of by predator insects. These tiny pests usually hide on the underside of leaves and are difficult to see because of their small size.
Petunia flowers attract hummingbirds and butterflies because of their rich floral scent, adding a touch of beauty to your garden while promoting pollination and plant growth.
