Fanflower (Scaevola aemula) is a relatively new annual bedding plant choice. This Australian native thrives in tough environmental conditions, including the hot, humid summers in the Southern U.S.
Fanflower grows well in hanging baskets, containers or garden beds. It grows in average, moderately acidic, well-drained soil and prefers full or partial sunny areas in the garden.
Non-stop powder blue flowers arise in the leaf axils on trailing stems. Once established, tough hardy fanflowers are only stopped by a heavy frost in late fall in the Southern Appalachian region (USDA hardiness zones 6 and 7). The medium green, oval-shaped toothed leaves average 2-inches in length.
Exhibiting a trailing growth habit, fanflowers grow vigorously, 6 to 9 inches tall and spreading up to 24 inches wide along with adequate summer moisture and nutrition. Some taller forms are available. Fanflower has no serious insect or disease problems.
Typical blue fan-shaped summer flowers give the plant its name. The Surdiva® series features 3 colors: blue, light blue, and white. They make ideal edging plants in containers or garden beds mixed with other annuals and perennials. The Bombay® series includes a pink flowering form, ‘Bombay Pink’.
