Attracting a multitude of butterflies, Conoclinium greggii (Palm-leaf Mistflower) is a spreading perennial boasting an abundance of small, fuzzy, lavender-blue flowers held in 2 in. clusters (5 cm). Depending on the geographic area, Palm-leaf Mistflower blooms as early as spring or from midsummer until frost, with peaks in early fall. The ageratum-like blossoms are carried by short stems and attract impressive numbers of butterflies, including monarchs and queens. They grow above the dense foliage of palmate leaves, which is deeply divided into three green lobes. Native to the southwestern United States, Palm-leaf Mistflower adds color to the late season garden when many other plants are starting to fade. Easy to grow, carefree, and adored by butterflies, it can be used as a ground cover or in the rock garden.

  • Grows up to 12-18 in. tall (30-45 cm) and 12-24 in. wide (30-60 cm). Can spread aggressively by rhizomes.
  • Performs best in medium moisture, well-drained loams in full sun to part shade. Drought tolerant once established.
  • No significant pest or disease issues.
  • Propagate by seed or softwood or semi-hardwood cuttings. Sow seeds directly after final frost. Softwood or semi-hardwood cuttings in summer or fall.
  • Native to Texas, New Mexico, Arizona and northern Mexico.
