Gregg’s Blue Mistflower is a Texas native perennial that brings a soft, airy touch to the landscape with its clusters of fuzzy, lavender-blue flowers. Blooming from late summer into fall, it’s a magnet for pollinators, especially butterflies like Monarchs and Queens, making it an excellent choice for wildlife-friendly gardens. Its ability to spread by rhizomes allows it to form low, dense colonies that work well as a groundcover in informal beds or naturalized areas.
This plant thrives in full sun to partial shade and prefers well-drained soils. It tolerates a range of soil types, including clay and those with alkaline pH, which makes it well-suited for much of Texas. Drought-tolerant once established, it benefits from occasional irrigation during extended dry periods.
Gregg’s Blue Mistflower grows to about 1–2 feet tall and can spread 3 feet or more, so give it room to naturalize or plan to thin clumps as needed. It pairs beautifully with ornamental grasses, salvias, and other native perennials for a layered, pollinator-friendly border.
In colder parts of Texas, the plant may die back to the ground after a hard freeze. Cut back the dead foliage in late winter or early spring to encourage fresh growth as temperatures warm.
