Is Scaevola a perennial or annual?
Scaevola is typically grown as an annual in most regions, including the SC Upstate. However, it is a perennial plant in its native habitat, Australia, and other warm climates. In areas with mild winters, such as USDA hardiness zones 9-11, Scaevola may behave as a perennial, returning year after year. Scaevola thrives in full sun, requiring 6-8 hours of direct sunlight daily. This exposure not only promotes robust growth but also enhances the plant’s vibrant colors and overall health. In areas with partial shade, Scaevola can still flourish with 3-6 hours of direct sunlight or filtered light.Scaevola can tolerate windy conditions as well, but the more abusive the location, the more frequent you should water. Water daily — and twice daily in very hot weather. Fertilize with a water-soluble fertilizer every week. Avoid frequent wilt-downs as this can make the plant look sparse and ropey.

Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowers. Regular deadheading encourages continuous blooming. Prune your Scaevola back after the first flush of flowers to promote bushier growth and additional blooms. The No-Deadhead Dream: Scaevola is 100% self-cleaning. The old flowers simply dry up and fall off, replaced immediately by new ones.
