Billy Buttons are curious Australian native flowers, especially well-suited for fresh cut and dried arrangements. Silvery tufts of narrow, grass-like foliage produce perfectly round, bright yellow 1 in. spheres that sit on top of 2-2.5 ft. long, stiff stems. Include Billy Buttons in sunny borders and mixed container plantings for unusual charm. Plants tolerate heat and heavy soil. Can be grown as a tender perennial in zones 8-11.
