During spring, summer, and fall, the plant produces delightfully fragrant, white flower clusters. Flowering is followed by fruit is a cypsela (pl. cypselae). though technically incorrect, the fruit is often referred to as an achene that add vibrant visual contrast and seasonal interest. It plays a vital ecological role as a larval host plant for Central Texas butterflies, including Rawson's Metalmark and Bordered Patch. Attracts hummingbirds, moths & butterflies. Butterflies and moths love the upright, fuzzy blooms. Thriving in clay, dry, gravelly, limestone, loam, sand, and well drained, White Mistflower demonstrates outstanding hardiness once established. It requires minimal supplemental water and adapts seamlessly to drought conditions. It features moderate deer resistance.
