Copper Canyon Daisy is highly aromatic, releasing a strong fragrance when its foliage is rubbed or brushed against, which is likely the reason that rabbits and deer leave this plant alone. Yellow-orange, daisy-like flowers develop in fall, and provide intense color through late fall, winter, and into early spring, if not damaged by frost. Lacy, dark green foliage is tipped with fragrant oil glands, which release a scent reminiscent of typical marigolds. Cut plant back hard in late winter or spring after blooming subsides to remove any frost-damaged foliage, to promote dense growth, and to keep it a nice shape. This drought-tolerant plant appreciates a little irrigation, but too much water or too little light can produce leggy plants with sparse flowers. Plant Copper Canyon Daisy back from high traffic areas, due to its brittle stems. While not long-lived, this fast-growing plant works well in the background to set off shorter plants in front.
