Eriogonum elongatum, commonly known as Longstem Buckwheat, is a perennial herb that thrives in the coastal sage scrub, foothill woodlands, and chaparral ecosystems of coastal southern California and Baja California. This species typically grows 2 to 4 feet tall and is recognized for its slender, erect stems and clusters of small, creamy yellow flowers that bloom from June to September, attracting a variety of pollinators.

Longstem Buckwheat is valued for its drought tolerance and ability to adapt to a wide pH range, including the challenging serpentinite soils. It is often used in native plant gardens, restoration projects, and xeriscaping due to its low water requirements and ability to provide habitat for beneficial insects and pollinators. In cultivation, it prefers full sun to light shade and requires well-drained soils. While generally low-maintenance, it can be susceptible to root rot in poorly drained conditions.CC BY-SA 4.0
