Azure bluets (Houstonia caerulea) are native to much of eastern North America, including Wisconsin. But they are rare in Wisconsin. These perennials grow about six inches tall.Their flowers, ranging from 1/4 to 1/2 inch in diameter, display a gentle blue hue with a contrasting yellow center. The foliage of azure bluets is distinct. Their opposite leaves have smooth edges. The basal leaves—located at the base of the plant—are one to two inches long, while the two smaller leaves on the stem range from 1/2 to one inch in length.
These flowers thrive in well-drained soil with a slightly acidic to neutral pH, ideally between 6.0 and 7.0. While they prefer moderate sunlight, they can adapt to varying conditions, flourishing in both full sun and partial shade with at least six hours of light daily. This is why they can be found in meadows and woodlands. They grow best in regions with a temperate climate, particularly in USDA hardiness zones 3-8. Consistent moisture is important, and weekly watering supports their healthy development, especially during dry periods.
