Greenthread is a native Texas wildflower prized for its resilience and extended bloom season. This warm-season annual or short-lived perennial reaches 1–3 feet tall, producing vibrant yellow flowers with distinctive brown-to-reddish centers throughout spring, summer, and fall. Its threadlike foliage gives the plant its memorable name and adds textural interest to any landscape. Exceptionally drought-tolerant, greenthread thrives on dry, rocky soils over limestone—making it ideal for water-conscious gardeners and naturalized plantings across the Texas Hill Country and beyond. It's a powerhouse pollinator attractant, drawing bees and butterflies throughout its long blooming window (February–November). Plant in fall for best establishment and germination rates of 60% or better. Our Non-GMO, heirloom seeds are sustainably grown and packaged in environmentally responsible, reusable, and recyclable materials. David's Garden Seeds, a Veteran-owned company since 2009, stands behind every packet with a commitment to quality and ecological stewardship.
