Flossflowers love well-draining soil, neutral-to-acidic. In containers, ideal growth can be achieved with monthly feeding with a balanced liquid fertilizer. Blooms seem to retain their flower color for an endless duration, so deadheading is typically not necessary. Just remember, plant this monarch "magnet" in full sun so that it can soak in six or more hours of bright light each day. For the pollinators' sake, avoid chemicals as you tend areas where this is grown.
