About Eriogonum elongatum Benth.
Eriogonum elongatum Benth. is a perennial herb that grows 0.6 to 1.2 meters (2.0 to 3.9 feet) tall. Its cauline leaves are roughly 1 to 3 centimeters (0.39 to 1.18 inches) long and 0.5 to 2 centimeters (0.20 to 0.79 inches) wide, and both its leaves and stem are typically covered in dense, woolly tomentose hairs. This species has a haploid chromosome number of n=34. It grows primarily in coastal sage scrub, foothill woodland, and chaparral ecosystems located in and around the Coast, Transverse, and Peninsular Ranges of California, at elevations between 60 and 1,900 metres (200 and 6,230 feet) above sea level. Like many other species in the Eriogonum genus, Eriogonum elongatum is a bodenvag species, meaning it tolerates a relatively wide soil pH range of 5 to 8.2. It can also grow in the serpentinite soils common across its native range, though it is not endemic to soils derived from serpentine. Eriogonum elongatum provides support for multiple organisms in its habitat, including native bees, parasitic and predatory insects, and butterflies. The butterfly species it hosts include Mormon metalmark (Apodemia mormo), Bramble Hairstreak Butterfly (Callophrys perplexa), Comstock's Hairstreak (Callophrys sheridanii comstocki), Bernardino Dotted-Blue (Euphilotes bernardino), Small Dotted-Blue (Philotiella speciosa), Acmon Blue (Plebejus acmon), and Lupine Blue (Plebejus lupini).
