Eriogonum parvifolium
Also called Seacliff Wild Buckwheat
Eriogonum parvifolium is a species in the family Polygonaceae that occurs on dune formations in the coastal area of Central and Southern California. This evergreen shrub grows to a height of 30 to 100 centimeters with a spread of approximately the same dimension. This plant is an important host for a number of pollinating insects including certain endangered species. E. parvifolium occurs both on bluffs along the Pacific Ocean coast as well as Coastal Strand dunes formations, but is restricted to altitudes below 700 meters. In at least one instance within the Carbonera Creek watershed, it occurs farther inland in a Maritime Coast Range Ponderosa Pine forest. This shrub is also known by the common names dune buckwheat, coast buckwheat, cliff buckwheat, seacliff buckwheat, or seacliff wild buckwheat.
E. parvifolium grows in sandy soils with pH ranging from five to eight (e.g. tolerates mildly acidic to mildly alkaline soils). In cultivation this species will actually tolerate clay soils. While this shrub grows in part to full sun, it may tolerate shade in cultivation. It is not subject to herbivory by deer, although many smaller fauna will consume its flowers, fruits and leaves. This species thrives in rainfall regimes of 39 to 78 centimeters per annum.
