Maccart’s Sundrops

Calylophus hartwegii ssp. maccartii, commonly known as Maccart’s Sundrops, is a perennial herb native to the southwestern United States and northern Mexico, particularly thriving in arid regions. This species typically grows to a height of 12 to 24 inches, forming a clumping habit with upright stems that bear bright green, linear leaves. The striking yellow flowers, which bloom from late spring to early summer, are cup-shaped and attract various pollinators, including bees and butterflies. The plant produces small, elongated seed capsules that release seeds upon drying, aiding in its propagation in suitable habitats.

Maccart’s Sundrops plays a vital ecological role in its native habitat, providing nectar for pollinators and serving as ground cover that helps prevent soil erosion. It is well-adapted to dry conditions, exhibiting drought tolerance once established, and can survive in nutrient-poor soils. This species has potential human uses in xeriscaping and as an ornamental plant due to its vibrant flowers and low maintenance requirements. Its ability to thrive in harsh environments makes it an excellent choice for sustainable landscaping in similar climates.
