Estimated Native Range
Summary
Hypericum gentianoides, commonly known as Orangegrass or Pineweed, is an annual herb native to dry, open woodlands and sandy fields in the Eastern United States, particularly thriving in the coastal plains. It typically grows to a height of 0.5-1 feet (0.2-0.3 meters) and a width of 0.5-0.8 feet (0.2-0.2 meters). This plant forms a low, tufted mound with slender, wiry stems and small, linear leaves. The bright yellow flowers, which bloom in late summer to early fall, are small but numerous, creating a delicate, airy effect.
Orangegrass is valued for its drought tolerance and ability to thrive in poor, sandy soils, making it an excellent choice for xeriscaping and naturalistic plantings. It is often used in rock gardens, as a ground cover, or for erosion control on slopes. In cultivation, it requires minimal care, preferring full sun and well-drained soils. While it is not a heavy drinker, adequate water during prolonged dry spells will keep it looking its best. Orangegrass is not commonly affected by diseases or pests, but it can self-seed prolifically, which may be considered undesirable in some garden settings.CC BY-SA 4.0
