Eremogone congesta, commonly known as ballhead sandwort, is a perennial herb native to a variety of habitats including alpine meadows, dry slopes, and rocky outcrops in western North America, ranging from central Canada to the American Southwest. It typically forms a compact tuft of slender, upright stems reaching up to 16 inches tall, with needlelike to thready leaves that are adapted to its dry environment. The plant produces an inflorescence that is a cyme of showy white flowers, blooming from late spring to early summer. The fruit is a toothed capsule that releases reddish seeds when mature.

Ballhead sandwort is appreciated for its drought tolerance and ability to thrive in poor, rocky soils, making it a suitable choice for rock gardens, xeriscaping, and restoration projects. It requires minimal maintenance and is valued for its delicate appearance and resilience to challenging growing conditions. While it is not commonly used in large-scale landscaping, it can provide textural contrast and interest in specialized plantings. It prefers full sun to partial shade and well-drained soils. There are no significant disease or pest issues, but overwatering can lead to root rot.CC BY-SA 4.0
