What is Pericallis?

The term pericallis refers to a genus of flowering plants. Some of these plants are regularly cultivated in gardens, while others, like the common ragwort, grow wild in temperate North America. Scientists consider the genus pericallis to contain about 14 species, related to herbaceous plants that are native to Madeira and the Canary Islands. Some species of pericallis, notably Pericallis cruenta, Pericallis hybrida, and Pericallis senetti, are commonly cultivated as ornamentals. These perennials often bloom profusely and can be self-propagating.

The flowering plants of the pericallis family may produce blooms in many colors. Even within a single species, flowers may be blue, pink, red, purple and even white. Blooms may appear singular in shade, though some varieties produce bi-colored or tri-colored blooms.

These herbaceous plants may reach heights of 12 to 36 inches (30 to 90 cm). They mostly prefer partial to full shade, well-drained and moist soil, and temperate climates. These plants are usually best grown in climates where the average minimum temperature does not fall below 25 degrees Fahrenheit (-3.8 C). Because these plants do not typically respond well to either hot or cold temperature extremes, they should ideally be grown at temperatures between 55 and 72 degrees Fahrenheit (12.7 to 22.2 C).

Though pericallis plants may die back during the colder months in harsher climates, they are considered perennials. These self-sowing plants spread easily and are considered by some to be an invasive in damp, cool climates. Gardeners are typically advised to remove seed heads before they mature to prevent self-sowing and the spread of plants with the return of warm weather.

Most cultivated pericallis species produce blooms that resemble the common daisy. Their leaves are often triangular in shape and usually dark green in hue. Foliage may have a fuzzy surface texture. Blooms may appear in early spring and last through early summer. In cool, moist climates, blooms may last from early spring to early autumn.

These plants may be propagated by seed. For outdoor beds, seeds should be sowed in the autumn. Pericallis species can also be propagated by taking plant cuttings.

Though often sold as potted plants, pericallis species typically do not thrive well in a potted environment. In temperate climates where frost is not an issue, potted pericallis plants may be transplanted to outdoor garden beds. Some varieties, such as the pericallis senetti, are considered slightly more resistant to temperature extremes than others.

Pericallis is a genus of flowering plants within the daisy family, Asteraceae, known for its vibrant blooms. It originates from the Macaronesian Islands, particularly the Canary Islands, where it thrives in the cool, moist conditions of the region's woodlands and shaded areas.

There are about 14 recognized species of Pericallis, each with its own unique characteristics. These species vary in size, shape, and color, offering a diverse range of options for gardeners and plant enthusiasts to enjoy.

Pericallis prefers a cool, temperate climate with partial shade. It thrives in well-drained soil that is rich in organic matter. Consistent moisture is key, but the plant does not tolerate waterlogged roots. Mild temperatures and protection from strong winds will help ensure healthy growth and vibrant blooms.

Yes, Pericallis can be grown indoors with proper care. It requires a bright location with indirect sunlight and consistent temperatures between 60-70°F (15-21°C). Indoor gardeners should ensure high humidity and good air circulation around the plant. Regular watering, when the soil's surface begins to dry, will keep it flourishing.

Pericallis species can be either perennial or annual, depending on the specific type and growing conditions. In their native habitat, many are perennials, but in colder climates, they are often grown as annuals because they cannot survive freezing temperatures.

Pericallis is popular for its colorful, daisy-like flowers, making it a favorite for adding splashes of color to gardens. It's commonly used in borders, container gardens, and as bedding plants. Their ability to bloom in cooler temperatures also makes them ideal for spring and fall displays.
