Westhoff’s [Scalora catalog](https://www.westflowers.de/wp-content/uploads/2025/06/Flippingpage_Westhoff_2025_2026.pdf) lists Suntastic with the WESSCAESUN selection code, and the [Japanese plant-variety registration record](https://www.hinshu2.maff.go.jp/gazette/touroku/contents/315gaiyou.pdf) records WESSCAESUN under *S. aemula*. The catalog identifies yellow as part of the series’ flower-color range, while the exact selection’s yellow flowers are also described by [Greenhouse Grower](https://www.greenhousegrower.com/crops/scaevola-suntastic-2010-medal-of-excellence-and-editors-choice-nominee/). ## Siting and use Give it full sun or partial shade in well-drained loam. The [North Carolina Extension profile](https://plants.ces.ncsu.edu/plants/scaevola-aemula/) describes *S. aemula* as heat- and drought-tolerant, recommends regular water during active growth, and lists USDA zones 10a–11b. Outside those zones it is generally grown as a warm-season annual or protected from frost. Its fan-shaped flowers suit containers, hanging baskets, or a sunny bed. ## Maintenance Water container plants when the mix begins to dry and keep drainage open. Remove stems only as needed to shape the plant, and protect it from frost where it is not hardy.
