Fan Flower

What are Scaevola (Fan Flowers)?

Scaevola aemula, commonly called Fan Flower or Fairy Fan Flower, is a species of flowering plant in the Goodeniaceae family (goodenia family). Native to Australia, specifically southern Australia, Scaevola aemula are popular annuals and tender perennials (depending on the climate) grown for their uniquely shaped, fan-like flowers and long blooming season. Scaevola flowers are famous for their distinctive, asymmetrical “fan” shape, where the petals are all arranged on one side of the flower, creating a half-circle or fan appearance. They come in a wide array of colors, including blue, purple, lavender, pink, rose, white, and bi-colors, often with a contrasting yellow or white throat. Scaevola aemula plants are characterized by their trailing or mounding growth habit, small, often slightly succulent leaves, and delicate stems. They exhibit a trailing, spreading, or mounding growth habit, typically reaching 6-12 inches in height and spreading 12-36 inches or more, depending on the cultivar and series. They are known for their unique flower shape, wide color range, long blooming season (spring to fall), sun-loving nature, and relative ease of care, making them an invaluable addition to gardens and containers, especially for adding a touch of whimsy, texture, and continuous color.

Are Scaevola Good for Outdoor Pots?

Yes, Scaevola aemula are exceptionally well-suited for outdoor pots and container gardening, and are in fact mostcommonly grown in containers, hanging baskets, and window boxes. Their trailing, spreading, or mounding growth habit, exceptionally long blooming season, tolerance of sunny locations and heat, and uniquely shaped, colorful flowers make them ideal for filling pots, patio containers, hanging baskets, and mixed container arrangements for sunny locations. Scaevola thrive in full sun and bloom profusely from spring until frost, providing an incredibly long-lasting and delightful display in containers. Their relatively easy-care nature and continuous, self-cleaning blooms make them a fantastic and rewarding choice for container gardens of all styles, especially for creating cascading displays, groundcover effects, or adding unique texture and form to patios, balconies, and decks. Growing Scaevola in pots also allows you to easily move them to optimal locations to enjoy their beauty, to follow the sun, and to control their growing conditions, especially soil drainage which they appreciate.

Ideal Growing Conditions for Scaevola in Pots:

• Types of Scaevola for Pots: Many Scaevola aemula varieties and series are excellent for pots, but consider your desired growth habit, flower color, and size when choosing:

  • Trailing Scaevola: Most Scaevola are naturally trailing or spreading, making them ideal for hanging baskets, window boxes, and spilling over the edges of pots. Look for series like ‘ Surdiva Series’, ‘ Whirlwind Series’, ‘ Sundance Series’, ‘ Topaz Series’, and ‘ Megaflora Series’ (some trailing types). These are best for baskets and containers where cascading growth is desired.
  • Mounding Scaevola: Some Scaevola varieties have a more mounding or semi-trailing habit, making them suitable for pots and mixed containers where a less aggressively trailing plant is preferred. Look for series like ‘ Bombay Series’, ‘ Scoop Series’, ‘ Fairy Wings’, ‘ New Blue’, and ‘ Purple Haze’. These work well in pots and combinations.
  • Large-Flowered Scaevola: Some newer Scaevola varieties boast larger flowers for a more dramatic display. Look for series like ‘ Megaflora Series’ (large flowers), ‘ Big Viola’, and some selections within the ‘ Bombay’ and ‘ Surdiva’ series.
  • Color Themes (for Pots): Choose varieties based on your desired color palette for your container garden. Scaevola offer a range of cool and warm colors.
    • Blues & Purples: ‘ Surdiva Blue Violet’, ‘ Bombay Dark Blue’, ‘ New Blue’, ‘ Purple Haze’, ‘ Whirlwind Blue’, ‘ Sundance Blue’.
    • Pinks & Roses: ‘ Surdiva Pink’, ‘ Bombay Pink’, ‘ Fairy Wings Pink’, ‘ Raspberry Ripple’, ‘ Rosea Compacta’, ‘ Pink Wonder’.
    • Whites & Creams: ‘ Surdiva White’, ‘ Bombay White’, ‘ Whirlwind White’, ‘ Sundance White’, ‘ White Sparkle’, ‘ Snow Maiden’.
    • Bi-colors & Patterns: ‘ Surdiva Goodness Gorgeous’, ‘ Bombay Trailing Blue’, ‘ Sundance Improved’, ‘ Whirlwind Improved’, ‘ Lavender Touch’, ‘ Blue Bayou’.

• Light: Scaevola thrive in full sun. They need at least 6-8 hours of direct sunlight per day to bloom profusely and develop their best, most vibrant colors. Choose a sunny location for your Scaevola containers, such as a south-facing patio, balcony, or garden bed. In partial shade, Scaevola will produce fewer blooms, become leggy, and their flower colors may be less intense. Full sun is essential for optimal flowering, vibrant colors, and compact, floriferous growth.

• Soil: Scaevola need well-draining soil that is moderately fertile and slightly acidic to neutral. They are susceptible to root rot in soggy conditions. Use a high-quality potting mix specifically formulated for containers or flowers. Amend potting mix with perlite, vermiculite, or horticultural grit to improve drainage and aeration, which is crucial for Scaevola. Avoid heavy, compacted soil or garden soil in pots, as they can become waterlogged. A slightly acidic to neutral pH (around 6.0-7.0) is ideal for Scaevola.

• Watering: Scaevola need consistently moist soil, but they also need excellent drainage and dislike being waterlogged. Water thoroughly when the top inch of soil feels slightly dry. Water deeply until water drains out of the drainage holes. Allow the soil surface to dry out slightly between waterings, but do not let the soil dry out completely, especially during hot weather or when plants are in full bloom. Avoid overwatering and constantly soggy soil, which can lead to root rot. Scaevola prefer a “moist but not soggy” soil environment. Watering frequency will depend on weather conditions, light levels, pot size, and plant size. During hot summer months, you may need to water daily or even twice a day for hanging baskets and smaller pots in full sun or windy locations. Check soil moisture regularly and adjust watering accordingly. Water at the base of the plant or use overhead watering early in the day to allow foliage to dry before evening, which can help prevent fungal diseases.

• Temperature: Scaevola are warm-weather plants that thrive in warm temperatures. They perform best in temperatures between 65°F to 85°F (18°C to 29°C). They are heat-tolerant and bloom well through the summer, but extreme heat (above 90°F/32°C) can temporarily slow blooming. Scaevola are frost-tender and are not cold-hardy. They are typically grown as annuals in most climates (USDA zones below 9). In USDA zones 9-11, Scaevola can be tender perennials, often blooming year-round in mild coastal areas. In colder zones, they are typically grown as annuals and enjoyed for the warm season. Potted Scaevola are easy to move to optimal locations to enjoy their beauty and follow the sun. They do not tolerate frost or freezing temperatures.

• Fertilizer: Scaevola are moderate feeders and benefit from regular fertilization to support their long blooming season and healthy growth. Consistent fertilization encourages continuous flowering. Fertilize regularly during the growing season (spring to fall) with a balanced liquid fertilizer (e.g., 10-10-10 or 20-20-20) diluted to half strength, every 2-3 weeks, or according to product label instructions. For containers, more frequent feeding (e.g., every 3 weeks) may be beneficial due to leaching from watering. Alternatively, you can use a slow-release granular fertilizer incorporated into the potting mix at planting time, but supplement with liquid feed throughout the season, especially for heavy bloomers. Choose a fertilizer formulated for flowering plants, or a balanced fertilizer. Regular, consistent feeding is beneficial for Scaevola to fuel their continuous blooming.

Choosing the Right Pots for Scaevola:

• Suitable Pot Types: Scaevola are exceptionally versatile in pot types, thriving in hanging baskets, window boxes, terracotta pots, ceramic pots, plastic pots, and resin pots. Consider these factors when selecting pot types for Scaevola:

  • Hanging Baskets: Scaevola are a classic choice for hanging baskets, showcasing their cascading or trailing habit beautifully. Use coco coir, moss-lined, or plastic hanging baskets, ensuring good drainage and adequate size for the desired display. Hanging baskets are ideal for Scaevola’s trailing growth.
  • Window Boxes: Scaevola are also excellent for window boxes, creating a long, colorful spill of blooms. Use window boxes with good drainage and adequate depth for root growth. Mass plantings in window boxes are very effective.
  • Terracotta Pots: Porous, allow good aeration and drainage, and aesthetically classic and warm-toned, complementing Scaevola’s natural charm. Terracotta is a good choice for Scaevola as it provides good drainage and a classic look. However, terracotta pots also dry out more quickly, which may require more frequent watering, especially in sunny, warm locations. Monitor soil moisture closely.
  • Plastic Pots: Lightweight, inexpensive, retain moisture well, and are available in various colors and styles. Excellent choice for Scaevola, especially for moisture retention and for larger pots and hanging baskets that need to be moved. Choose good quality plastic pots with drainage holes. Plastic pots help retain moisture, which can be beneficial, especially in sunny locations and for busy gardeners.
  • Resin Pots: Lightweight, durable, available in various styles mimicking terracotta or ceramic, and offer a balance of drainage and moisture retention. A good alternative to heavy ceramic pots, and often more durable than terracotta or plastic. Resin pots also retain moisture well, similar to plastic.
  • Decorative Containers: Scaevola’s unique flower shape and vibrant colors work well in a variety of decorative containers. Choose pots that complement your outdoor décor and enhance the cheerful, whimsical nature of Fan Flowers.

• Drainage: Excellent drainage is absolutely essential for Scaevola to prevent root rot. They are highly susceptible to root rot in soggy conditions. Ensure your chosen pot has drainage holes at the bottom. Avoid pots without drainage holes. Adding a generous layer of perlite or pot shards at the base of the pot is highly recommended to further improve drainage, especially in heavier pots or if you tend to overwater. Elevating pots slightly on pot feet or bricks can further improve drainage and air circulation around the base.

• Pot Size: Choose pot sizes appropriate for the mature size and growth habit (trailing vs. mounding) of the Scaevola you are planting, and the desired visual impact. Scaevola have moderately sized root systems, but their spreading or trailing growth benefits from adequate root space and stability.

  • Small Pots (Individual Plants, Compact Types): For individual, compact Scaevola plants in small pots, use pots that are at least 6-8 inches in diameter and at least 6 inches deep. These are suitable for very dwarf or upright varieties, or for starting individual plants.
  • Medium Pots (Patio Containers, Combinations, Mounding Types): For patio containers, mixed arrangements, or mounding varieties, use pots that are 10-14 inches in diameter or larger and at least 8-10 inches deep. These provide more root space and moisture retention.
  • Hanging Baskets & Window Boxes (Trailing Types): For hanging baskets and window boxes, choose sizes that are at least 10-12 inches in diameter or larger and at least 8 inches deep for smaller displays, and larger for more dramatic, overflowing baskets. Window boxes should be at least 8-10 inches deep and as long as desired, allowing about 10-14 inches of spacing per plant for good coverage.

• Color and Style: Choose pot colors and styles that complement your Scaevola blooms and your outdoor décor, and enhance their cheerful, whimsical nature. Brightly colored pots can enhance the vibrant colors of Scaevola blooms. White, cream, or pastel pots can create a more classic, elegant look, allowing the flower colors to pop. Terra cotta or natural-look pots can provide a more earthy, garden-style feel. Whimsical, patterned, or modern pot styles can all work well with Scaevola, depending on your personal taste and garden style. Consider the overall style of your patio or garden and choose pots that harmonize with the surroundings, and enhance the bright, colorful, and playful ambiance you wish to create.

Essential Care Tips for Thriving Scaevola in Outdoor Pots:

• Watering: “Keep Soil Consistently Moist, Allow Surface to Dry Slightly, Avoid Soggy Soil”. Water thoroughly and regularly to maintain consistently moist soil, especially during hot weather and active blooming. Water deeply when the top inch of soil feels slightly dry. Allow the soil surface to dry slightly between waterings. Avoid overwatering and constantly soggy soil. Consistent moisture is key, but drainage is equally important.
• Sunlight: Provide Full Sun (6-8+ Hours Daily). Place Scaevola pots in a location that receives full sun for optimal growth, blooming, and vibrant colors.
• Fertilizing: Fertilize Regularly, Every 2-3 Weeks During Growing Season. Fertilize every 2-3 weeks with a dilute balanced liquid fertilizer, or use slow-release fertilizer supplemented with liquid feed. Regular, consistent feeding is beneficial for prolific blooming.
• Self-Cleaning: No Deadheading Needed. Scaevola are self-cleaning, meaning they naturally drop their spent flowers, so deadheading is not necessary. This is a major advantage, saving time and effort.
• Pruning/Trimming (Optional, for Shaping or Rejuvenation): While not required for blooming, you can lightly trim back Scaevola if they become overly leggy or straggly mid-season, or to encourage bushier growth. Use scissors or pruners to trim back stems by about 1/3, if desired. They will quickly regrow and bloom again.
• Heat Tolerance: Very Heat Tolerant, but Protect from Frost. Scaevola are very heat-tolerant and bloom well through hot summers. However, they are frost-tender and must be protected from freezing temperatures.
• Pest and Disease Control: Scaevola are generally relatively pest and disease-resistant, but monitor for occasional pests like aphids, spider mites, and whiteflies, especially in hot, dry conditions. Fungal diseases like root rot can occur if soil is kept too soggy or drainage is poor. Ensure good air circulation by spacing plants adequately, avoid overcrowding, provide excellent drainage, and avoid overwatering. Treat any pest or disease issues promptly with insecticidal soap, horticultural oil, neem oil, or appropriate fungicides if necessary.
