Interesting Notes:

Petchoa is a semi-trailing to trailing, annual and tender perennial. This revolutionary hybrid is a fairly new genus; a result of the genetic cross between a petunia and calibrachoa. The Petchoa plant features the best characteristics of two top selling species. They inherit strong roots, providing good pH tolerance and foliage health under stressful conditions, excellent plant vigor, large flowers, and ease of growing from their Petunia parent. The Calibrachoa side contributes the genes for an intense and vibrant flower that holds up under severe weather, and lush but non-sticky foliage that maintains a fresh clean look not requiring additional maintenance.

Supercal, a series developed by Sakata, includes eleven different varieties, each conveying a uniquely colored blossom. This vigorous plant will grow two-inch bell shaped flowers on rich green foliage. It is commonly used in hanging baskets, container combinations, and for mass planting in the landscape. Taller and fuller varieties go nicely as mixed fillers in the garden. Supercal grows best in moist, fertile, well-drained soil, and is a full to partial sun exposure flower. A unique feature of Supercal is its ability to maintain color while tolerating the early cooler temperatures in the 20’s, remaining unharmed by frost, and the higher temperatures, without being scorched by the heat. Petchoa will continuously bloom all season long. Key features of this variety include heat, frost, and drought tolerance, and no deadheading required.

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 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. Petchoa Supercal is a full to partial sun annual that thrives in the heat. The best time for planting your flower is mid-spring or early summer, after the threat of frost has passed. Be careful not to take your plant outside too early in the spring. If there is still a chance of frost in your area, keep your plant safe indoors, maintaining care in the container. Supercal 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, and are sure to provide a color canopy all season long.

Supercal is a low maintenance plant that is heat tolerant. While it has a high tolerance level, water application a few times a week is still recommended, and fertilizer or compost application will ensure optimal plant performance. 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. Supercal requires a good moisture level to properly grow 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.

These beauties will continuously bloom all season. While the plant does not require deadheading, if your plants start to look messy, feel free to trim them back to keep them tight and well shaped. After pinching back, your plant should begin to bloom again within 1–2 weeks. Unlike Petunia blossoms, Petchoa flowers are not sticky and messy, even after rainfall, and will release old flowers so that new blooms can form.

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. Supercal are vulnerable to many of the same pests that threaten its parent plant, Calibrachoa. Aphids, thrips, and leaf miners are the main pests to be looked for and treated.

The earliest prevention against disease and pest threat is careful examination during the purchasing process. Observe plant health as a whole as well as flower health. It is important to know the difference between harmful pests and beneficial insects. Do not panic if you notice a few insects around your flowers. Simply follow these steps: place a sticky trap above the plant of interest, secure a few insect samples, make a diagnosis as to the threat level, and treat accordingly. Supercal flowers attract hummingbirds and butterflies, adding a touch of beauty to your garden while promoting pollination and plant growth.
