Blue-eyed Mary is a charming spring wildflower native to American woodlands, prized for its delicate bi-colored blooms in shades of blue and white that appear from April through May. This winter annual thrives in hardiness zones 2-11, growing 12-24 inches tall with a spread of 9-18 inches on weak, slender stems. In its native habitat across Iowa, Wisconsin, and the eastern United States, it's known for carpeting entire acres in sprawling drifts, and it brings that same generous, naturalized charm to home gardens. The plant self-seeds readily, returning year after year once established, and requires only moderate water and low maintenance to flourish.

Blue-eyed Mary's most captivating feature is its two-lipped flowers in striking blue and white, which bloom abundantly in spring on opposite-leafed stems in rich woodland soil. The plant's natural habit of self-seeding means once you introduce it to a garden, it often becomes a persistent, welcome volunteer. Its preference for dappled light and moist, well-drained loam makes it particularly valuable for partially shaded areas where many annuals struggle.
Blue-eyed Mary is grown as an annual ornamental flower, valued for its spring display in woodland gardens, shade borders, and naturalized settings. Gardeners cultivate it specifically for creating drifts of color in areas too shaded or moist for conventional annuals, and its self-seeding habit makes it a low-maintenance choice for gardeners seeking spontaneous, seasonal color.
No timeline data available yet for this variety.
Sow seed directly outdoors in summer to early fall. Seeds germinate in fall, and the tiny seedlings overwinter, emerging to bloom the following spring. This winter annual cycle means timing is critical: sowing too late may not allow adequate root establishment before winter, while sowing too early may lead to blooming before frost.
