Artist Blue Flossflower

Artist® Blue is the vegetatively propagated ageratum ‘Agsantis’, grown as a compact annual for a sustained display of soft blue to violet-purple flower clusters. Its mounded habit suits containers, baskets and borders, where it continues flowering through warm weather ([Proven Winners](https://www.provenwinners.com/plants/ageratum/artist-blue-flossflower-ageratum)). ## Garden Use and Bloom The breeder describes ‘Agsantis’ as a uniform, weather-tolerant selection with a mound of deep violet-purple flowers. It grows about 8–12 inches tall and 6–10 inches wide, and blooms in spring, summer and fall until hard frost in its listed USDA zones. New flowers cover faded ones, so routine deadheading is unnecessary. Its flowers attract bees, butterflies, birds and hummingbirds ([Proven Winners professional profile](https://pros.provenwinners.com/plant-details/?ID=1047)). ## Growing Conditions Plant in part sun to full sun and average soil. Water regularly enough to support continuous flowering, especially in pots, and feed container plants during the growing season. The cultivar is listed for USDA zones 9a–10b; gardeners elsewhere can grow it as a warm-season annual after frost danger has passed. University of Wisconsin Extension describes the Artist series as compact and mounding, generally around 8–10 inches tall ([Ageratum](https://hort.extension.wisc.edu/articles/ageratum/)). ## Maintenance Remove damaged stems or trim a plant that has become untidy; routine deadheading is not needed. Add compost or fertilizer to support steady growth, with more regular feeding in containers, as the breeder recommends.
