Cyclamen

What is Cyclamen (Persian Violet)?

Cyclamen, scientifically known as Cyclamen persicum, is a popular cool-season flowering perennial belonging to the Primulaceae family (formerly classified in Cyclamenaceae or Myrsinaceae). Native to the eastern Mediterranean region, from Turkey and Lebanon to Israel and parts of North Africa, they are widely cultivated as ornamental plants, especially for winter and spring color, prized for their uniquely shaped, nodding flowers, attractive heart-shaped, marbled foliage, preference for cool temperatures, and suitability for pots and indoor growing. Cyclamen plants are characterized by their rounded, often flattened corms (underground storage organs), heart-shaped to kidney-shaped leaves that are often beautifully patterned with silver or lighter green marbling, and distinctive, reflexed flowers held on slender stems above the foliage. Flowers have five petals that are swept back, resembling butterfly wings, and come in a range of colors, including white, pink, red, purple, and bi-colors, often with darker markings at the base of the petals. They exhibit a compact, mounding growth habit, typically reaching heights of 6-9 inches and spreading 9-12 inches wide, making them well-suited for pots and smaller spaces. They are known for their winter and spring blooms, preference for cool conditions, delicate beauty, and adaptability to container culture, making them a popular choice for homes, patios, balconies, and as gifts, especially for adding color during the colder months. In Chinese culture, it is known as 仙客来 (Xiānkèlái), meaning “cyclamen” or “heavenly guests flower,” often associated with winter and the Lunar New Year.

Is Cyclamen (Persian Violet) Good for Outdoor Pots?

Yes, Cyclamen is well-suited for outdoor pots and container gardening, especially in regions with mild winters or during cooler seasons. Growing Cyclamen in pots offers several advantages:

• Ideal for Cool Seasons: Cyclamen thrives in cool temperatures, making them perfect for adding color to patios and balconies during fall, winter, and spring when many other flowering plants are dormant.
• Portability: Potted Cyclamen can be easily moved to optimal locations for light and temperature, or to create seasonal displays. You can bring them to sheltered spots during heavy rain or strong winds.
• Controlled Environment: Container gardening allows you to provide the well-draining soil mix that Cyclamen prefers and control watering and fertilization precisely, which is important for their specific needs.
• Design Versatility: Cyclamen works beautifully as a standalone specimen plant in a decorative pot, or as part of mixed cool-season container arrangements, adding delicate and elegant blooms.
• Pest and Disease Management: Container growing can help reduce some soilborne pest and disease issues that can affect Cyclamen planted directly in the ground.
• Ideal for Patios and Balconies: Cyclamen in pots is perfect for adding a touch of winter and spring beauty to patios, balconies, and other outdoor living spaces, especially in shaded or partially shaded areas.
• Protection from Heat: In warmer climates like Singapore, growing Cyclamen in pots allows you to move them to cooler, shadier spots to extend their blooming period and protect them from excessive heat, although they are generally challenging to grow long-term in Singapore’s consistently warm climate.

Ideal Growing Conditions for Cyclamen (Persian Violet) in Pots:

• Light: Cyclamen prefers bright, indirect light and partial shade. When grown outdoors, they appreciate a location that receives filtered sunlight or morning sun and afternoon shade. Avoid direct, harsh sunlight, especially during the warmer parts of the day, as this can scorch their delicate leaves and flowers. A location with dappled shade or bright shade is ideal. North-facing patios or balconies, or spots under trees that provide filtered light, are often excellent locations. Too much shade, however, can result in weak growth and reduced flowering.

• Soil: Cyclamen needs well-draining soil that is rich in organic matter and slightly acidic. Use a high-quality potting mix specifically formulated for indoor plants or flowering plants. Amend potting mix with peat moss, perlite, or composted bark to improve drainage and aeration while retaining some moisture. Good drainage is essential to prevent corm rot, which Cyclamen are susceptible to. Avoid heavy, waterlogged soil. A slightly acidic to neutral pH (around 6.0-6.5) is ideal.

• Watering: Cyclamen prefers consistently moist soil during its active growing and blooming season, but dislikes soggy conditions. Water thoroughly when the top inch of soil feels slightly dry. Water deeply until water drains out of the drainage holes. Then, allow the topsoil to slightly dry before watering again. Avoid overwatering and consistently soggy soil, which can lead to corm rot. Also, avoid letting the soil dry out completely, especially when plants are actively growing and blooming. Cyclamen prefers a “moist but not waterlogged” soil environment. Watering frequency will depend on weather conditions, light levels, and pot size. Water more frequently during warmer, drier periods and less frequently during cooler, cloudier periods. Water from below if possible to avoid wetting the crown of the plant and foliage, which can encourage rot. You can set the pot in a shallow saucer of water and allow it to absorb moisture from the bottom for about 15-20 minutes, then remove and allow excess water to drain.

• Temperature: Cyclamen thrives in cool temperatures, ideally between 50-65°F (10-18°C). They are cool-season plants and perform best in cooler weather. Avoid high temperatures, especially above 70°F (21°C), as heat stress can cause them to go dormant prematurely and shorten their bloom time. In warmer climates like Singapore, maintaining cool temperatures for Cyclamen outdoors is challenging. However, you can try to grow them during the cooler months (e.g., December to February in Singapore) and place them in the shadiest and coolest spot possible, such as a north-facing patio, and ensure good air circulation. Consider bringing them indoors to air-conditioned environments during the hottest parts of the day or during prolonged warm spells to extend their bloom time in warmer climates. Consistent cool temperatures are crucial for their longevity and bloom duration.

• Humidity: Cyclamen prefers moderate humidity. Singapore’s humidity is generally acceptable, but ensure good air circulation around the plants to prevent fungal diseases, especially in humid conditions. Avoid overly humid, stagnant air.

• Fertilizer: Cyclamen benefits from light fertilization during the active growing and blooming season. Fertilize every 4-6 weeks during the blooming period. Use a balanced liquid fertilizer (e.g., 10-10-10 or 20-20-20) diluted to half strength, or a fertilizer specifically formulated for flowering plants. Follow product label instructions for application rates. Avoid over-fertilizing, as this can promote leafy growth at the expense of flowers. Reduce or stop fertilizing when flowering declines and the plant enters dormancy (typically as temperatures warm up).

Choosing the Right Pots for Cyclamen (Persian Violet):

• Suitable Pot Types: Cyclamen can be grown in various pot types, but good drainage and appropriate size are important. Suitable pot types include:

  • Terracotta Pots: Terracotta is a good choice as it is porous, allowing for good aeration and drainage, which is beneficial for Cyclamen and helps prevent overwatering.
  • Ceramic Pots: Unglazed or glazed ceramic pots can be used. Ensure they have drainage holes. Choose based on your desired aesthetic and pot size needs.
  • Plastic Pots: Plastic pots are lightweight and inexpensive and retain moisture well, which can be helpful in drier climates, but be extra careful not to overwater in plastic pots as they retain more moisture than terracotta. Choose good quality plastic pots with drainage.
  • Resin Pots: Lightweight, durable, available in styles mimicking terracotta or ceramic, and offer a balance of drainage and moisture retention. Resin pots are a good alternative to heavy ceramic or terracotta.

• Drainage: Good drainage is essential for Cyclamen to prevent corm rot. Ensure your chosen pot has drainage holes at the bottom. Avoid pots without drainage holes. Adding a layer of drainage material at the base of the pot (e.g., a layer of gravel, pot shards, or clay pebbles) is recommended to further improve drainage. Elevating pots slightly on pot feet or bricks can also improve drainage and air circulation.

• Pot Size: Choose pot sizes that are appropriate for the size of the Cyclamen corm and the desired display. Cyclamen do not need very large pots.

  • Small to Medium Pots (Most Common): For individual Cyclamen plants, pots that are 5-7 inches in diameter and about 6 inches deep are generally suitable. The pot should be just slightly larger than the corm. Overpotting can increase the risk of root rot.
  • Group Plantings: For planting multiple Cyclamen plants together in a larger display, use wider pots or bowls that are 8-12 inches in diameter or larger, depending on the number of plants.
  • Depth: Pots should be at least 6 inches deep to accommodate the corm and root system.

• Stability: Cyclamen are relatively small and lightweight plants and do not typically require exceptionally heavy or wide pots for stability. Standard pots are generally stable enough.

• Color and Style: Choose pot colors and styles that complement the delicate flower colors and marbled foliage of your Cyclamen and your outdoor décor, and enhance their elegant, cool-season appearance. Cool-toned pots in blues, greens, purples, white, silver, or gray can create a harmonious and sophisticated display, highlighting the cool-toned flowers and foliage. Terracotta pots can provide a warmer contrast. Consider the overall style of your patio or balcony and choose pots that harmonize with the surroundings and enhance the desired elegant, winter garden ambiance.

Essential Care Tips for Thriving Cyclamen (Persian Violet) in Outdoor Pots:

• Watering: “Keep Soil Moist, Avoid Soggy Soil and Overwatering”. Water thoroughly when the top inch of soil is slightly dry. Water deeply and ensure good drainage. Avoid overwatering and soggy soil. Water from below if possible.
• Light: Provide Bright, Indirect Light or Partial Shade. Avoid Harsh Direct Sun. Place Cyclamen pots in a location with bright, indirect light or partial shade outdoors. Protect from direct, intense sunlight.
• Temperature: Keep Cool (50-65°F/10-18°C) for Best Blooms. Provide cool temperatures. Protect from heat, especially above 70°F (21°C). Move to cooler, shadier spots or indoors if temperatures become too warm, especially in climates like Singapore.
• Fertilizing: Fertilize Lightly Every 4-6 Weeks During Blooming Season. Fertilize sparingly during the blooming season with a balanced liquid fertilizer. Avoid over-fertilizing.
• Deadheading (Encourage More Blooms): Deadhead spent flowers and yellowing leaves regularly to encourage more blooms and maintain a tidy appearance. Gently twist and pull spent flower stems from the base of the plant.
• Dormancy (Natural Summer Dormancy): Cyclamen naturally goes dormant in warmer weather (typically in summer). After blooming, foliage will start to yellow and die back. Reduce watering gradually as foliage fades. In warmer climates, allow the plant to go dormant in a cool, dry, and shaded location during the summer months. You can leave the corm in the pot or remove it and store it in a cool, dry place until fall.
• Re-starting After Dormancy (Cooler Weather): In fall, as temperatures cool down, you can repot the corm in fresh potting mix (if removed) or resume watering the potted corm that has been dormant. Place in a bright, cool location and gradually increase watering as new growth emerges.

Popular Cyclamen Cultivars (and Flower Colors & Forms):

Cyclamen cultivars are available in a wide range of flower colors, sizes, and forms.

• Flower Colors: White, Pink (light to dark shades), Red, Purple, Magenta, Lavender, Salmon, Bi-colors (often with contrasting eyes or petal edges).
