About

Eriogonum elongatum, commonly known as longstem buckwheat or wand buckwheat, is a species of wild buckwheat native to coastal southern and Baja California.

Where it grows

Eriogonum elongatum primarily grows in coastal sage scrub, foothill woodland, and chaparral ecosystems in and around the Coast, Transverse, and Peninsular Ranges of California from 60–1,900 metres (200–6,230 feet) above sea level. As with many other Eriogonum species, Eriogonum elongatum is a bodenvag species, tolerant of a relatively wide pH range of 5–8.2, and is tolerant of serpentinite soils that are common throughout its range, though it is not endemic to serpentine-derived soils.
