Cineraria, often referred to in horticultural circles as Pericallis, represents a small yet striking genus of flowering plants in the Asteraceae family. Among the various species, Pericallis × hybrida stands out as a popular choice for gardeners due to its vibrant and colorful flowers.

This comprehensive guide aims to provide all the necessary information on caring for cineraria, helping you enjoy these delightful blooms in your own garden.

Varieties of Cineraria

Let’s first resolve a terminological dilemma. The term “cineraria” is somewhat broad, covering several species within the genus Pericallis. The most widely cultivated is Pericallis × hybrida, most commonly known as Florist’s Cineraria, or Common Ragwort. It’s a hybrid primarily derived from Pericallis cruenta among other species. The array of colors available in this hybrid species is vast, ranging from deep purples and blues to vibrant pinks, reds, and whites.

Aside from Pericallis × hybrida, other species like Pericallis senetti, known for its large flowers and cold tolerance, and Pericallis cruenta, enhance the diversity within this genus. Each species has unique horticultural traits, tailored to different gardening needs.

The origins of Pericallis trace back to the cool ocean cliffs of South Africa, with some species from the Canary Islands and Madeira. Over time, to manage the extensive variety within the original Cineraria genus, many plants were reclassified into new genera, including Pericallis.

Another interesting variety is Cineraria maritima, or Silver Ragwort. It’s a perennial plant featuring silvery-grey foliage and yellow daisy-like flowers, commonly used for its decorative, contrasting foliage in gardens. It also is a medicinal plant appreciated for its soothing, decongestant, and anti-inflammatory properties.

Caring For Florist’s Cineraria Plants

But let’s focus on Florist’s Cineraria and learn the most important things to know in order to successfully grow and care for it:

Light & Temperature

Cineraria plants thrive best in environments that simulate their natural habitat—cool and dimly lit. They favor daytime temperatures ranging between 60-70°F and cooler night temperatures from 55-65°F. These conditions help them maintain their vibrant colors and overall health. Although cineraria can tolerate brief periods of temperatures as low as 35°F, they are vulnerable to frost, which can damage or kill the plants.

When grown outdoors, it is crucial to position them in areas that receive partial to full shade to shield them from harsh direct sunlight, which can lead to scorching of the leaves and stress the plants, potentially reducing their lifespan and blooming capacity.

Water & Humidity

Maintaining consistent moisture levels is essential for the well-being of cineraria plants. The soil should always feel moist to the touch but never waterlogged, as overly saturated roots can lead to root rot and other fungal issues.

Cineraria also thrives in high humidity environments which mimic the moist, cool climates they originate from.

Achieving this indoors can be facilitated by placing a pebble tray filled with water beneath the planting container or using a room humidifier. This setup helps create a microenvironment of increased humidity around the plants, which supports their lush, healthy growth.

Soil

Cineraria plants need a rich, moist, slightly acidic soil that has good drainage. The ideal soil composition for cineraria should be well-draining yet capable of retaining enough moisture to keep the roots adequately hydrated. An ideal soil mix includes components like sphagnum peat moss, vermiculite, loamy soil, and perlite or coarse sand. This combination ensures good drainage while still holding moisture.

Additionally, the soil should have a slightly acidic pH, which helps cineraria plants absorb nutrients more efficiently. Regularly checking the soil condition and making adjustments, such as adding more organic matter or sand to improve its structure, can significantly benefit the plants’ overall health and flowering capabilities.

Fertilizing

Fertilization is another crucial aspect of caring for cineraria plants. A balanced, water-soluble fertilizer applied lightly before the onset of the blooming period can promote vigorous growth and prolific flowering. However, once the plants start developing flowers, it is advisable to cease fertilizing. Continued application of fertilizer during the flowering stage can lead to excessive foliage growth at the expense of blooms.

Additionally, over-fertilization can accumulate harmful salts in the soil, which may damage the roots and reduce the plant’s ability to absorb water, ultimately affecting its health and aesthetic appeal. Regularly flushing the soil with water can help mitigate salt buildup and keep your cineraria flourishing.

Propagating Florist’s Cineraria Plants

Cineraria can be propagated through seeds or stem cuttings.

Propagating Cineraria from Seeds

Starting cineraria plants from seeds is a common and relatively straightforward approach. To achieve a steady bloom throughout the season, it’s beneficial to sow new seeds every two to three weeks. This staggered sowing ensures that as one batch of plants begins to decline after blooming, another is just coming into flower.

When sowing cineraria seeds, use a light, well-draining seed starting mix and place the seeds on the surface, gently pressing them into the soil without covering them, as they need light to germinate. Keep the soil consistently moist and in a cool, well-lit area until germination, which typically occurs within two to three weeks.

Once the seedlings have developed their first set of true leaves, they can be transplanted into individual pots or spaced out in the garden.

Propagating Cineraria from Stem Cuttings

This method can be a quicker way to get flowering plants, as it skips the seed germination stage. Choose healthy, non-flowering stems for cuttings to ensure the best results. Cut a 4-6 inch piece from the tip of the stem, strip the lower leaves, and dip the cut end into a rooting hormone to promote root growth.

Plant the cutting in a pot filled with a mixture similar to that used for seeds—light and well-draining. The cuttings should be kept in a humid environment, which can be easily created by covering the pot with a plastic bag or placing it in a mini-greenhouse. Ensure the soil remains moist but not soggy, and keep the pot in a bright area without direct sunlight. Roots typically begin to form within a few weeks, and once established, the plants can be transferred to larger pots or their final location in the garden.

Keep in mind that both methods of propagation require attention to environmental conditions such as light, temperature, and humidity.

Pests and Diseases

Aphids, whiteflies, and thrips are common pests that may afflict cineraria plants. Insecticidal soap is effective for managing these pests. Additionally, spider mites and the chrysanthemum leaf miner might also pose threats, necessitating the use of neem oil or specific pesticides like Mite-X.

Among the most common diseases that Cineraria plants face, one can’t help mentioning Botrytis cinerea (gray mold) and powdery mildew. These two are the primary fungal issues for cineraria. These can be treated with neem oil or copper fungicides. Common rust and soil-dwelling fungi that cause root rot can also affect the health of the plant. Using sterile soil and ensuring good drainage can help prevent these problems.

Some Frequently Asked Questions

To finish with, here are our answers to the most common questions regarding this beautiful plant.

Is cineraria an annual or perennial?

Cineraria, particularly the florist’s cineraria (Pericallis × hybrida), is typically grown as an annual. In warmer climates (zones 9-10), it can behave as a tender perennial.

Is cineraria an indoor plant?

Cineraria can be grown as an indoor plant. It thrives when protected from direct sunlight and extreme heat. These plants need conditions where they can receive bright, indirect light and maintain cooler temperatures.

Is cineraria an evergreen?

Cineraria, specifically varieties like Cineraria maritima (Silver Ragwort), is typically evergreen in milder climates where frost is minimal. In colder regions, it may lose its leaves and behave more like a deciduous plant.

We hope you found this exploration into the secrets of this plant enlightening and enjoyable With the right care, cineraria can add a spectacular burst of color to your garden or home. It will certainly make it a rewarding addition to any plant collection.
