Plant Name
Scaevola Whirlwind Blue
Scientific Name
Scaevola aemula
Overview
Scaevola Whirlwind Blue is a trailing ornamental plant commonly used in containers, hanging baskets, and garden borders. The plant produces spreading stems that carry small fan-shaped flowers along their length. Its consistent flowering and trailing habit make it useful in mixed seasonal plantings.
Scaevola Whirlwind Blue care focuses on providing full sun, moderate watering, and well-drained soil. When planted in suitable conditions, the plant forms dense trailing growth and maintains steady flower production.
Plant Description
Scaevola Whirlwind Blue forms a low mound of branching stems that spread outward and trail over edges. The plant maintains a compact base while producing long trailing stems. This growth habit allows it to fill containers and soften the edges of planting beds.
Plants grow steadily during warm weather and maintain a balanced shape.
Flower Description
The plant produces distinctive fan-shaped blue flowers that appear along the stems rather than in clusters. Each bloom resembles half of a typical flower shape, creating the characteristic fan form.
Flowers continue forming throughout the growing season without significant pauses.
Foliage Description
Leaves are small, green, and slightly fleshy. The foliage forms a dense base that supports the trailing stems.
Healthy foliage helps maintain the plant’s overall fullness.
Deciduous or Evergreen
Herbaceous perennial in frost-free climates. Typically grown as a warm-season annual in cooler regions.
USDA Grow Zones
Perennial in zones 10–11. Commonly grown as an annual in cooler climates.
Mature Height and Width
8–12 inches tall
18–24 inches wide
Growth Habit

Water Requirements
Provide moderate watering during the growing season. Soil should remain slightly moist but not waterlogged.
Allow the soil surface to dry slightly between watering cycles.
Fertilizing
Light fertilization during the growing season may support steady flowering. A balanced fertilizer applied periodically is typically sufficient.
Excess fertilizer may produce excessive foliage growth.
Pruning and Maintenance
Scaevola generally requires little pruning. Light trimming may encourage branching and fuller growth.
Removing damaged stems helps maintain plant appearance.
Pests and Problems
Scaevola typically experiences few pest problems. Aphids or spider mites may occasionally appear during warm weather.
Maintaining proper watering and airflow helps prevent issues.
Disease Resistance
