Four-nerve Daisy (Tetraneuris scaposa), also known as Hymenoxys, Stemmy Four-nerve Daisy, or Bitterweed, is a hardy perennial wildflower native to dry plains and rocky hillsides. Thriving in well-drained, rocky, clay, or limestone-based soils, it is highly drought and heat tolerant. This low-growing plant features narrow, silvery-green leaves clustered near the base, with bright yellow, daisy-like flowers held on tall, leafless stalks. Each flower has three-toothed petal tips and four distinct dark purple veins, giving it its characteristic look. Blooming primarily from March to June, it may flower year-round in mild climates. Four-nerve Daisy is an excellent choice for rock gardens, borders, and xeriscapes, providing consistent color and nectar for pollinators.
