Botanical Name: Scaevola aemula Sun Exposure: Full sun, part shade Soil Type: Well-drained Soil pH: Acidic, neutral (6.0-7.0) Many hanging baskets struggle in dry heat, but fan flower is not one of them. This Australian native produces pretty fan-shaped blossoms in blue, purple, pink, or white. Water fan flower when the soil dries out, but don't stress if you occasionally miss a watering.
